Is there a CSS parent selector?

How do I select the <li> element that is a direct parent of the anchor element?

As an example, my CSS would be something like this:

li < a.active {
    property: value;
}

Obviously there are ways of doing this with JavaScript, but I'm hoping that there is some sort of workaround that exists native to CSS Level 2.

The menu that I am trying to style is being spewed out by a CMS, so I can't move the active element to the <li> element... (unless I theme the menu creation module which I'd rather not do).

Safari Tech Preview 137 today introduced the first implementation of the :has() selector.
coming soon: chrome!

There is currently no way to select the parent of an element in CSS, at least not a way that works across all browsers.

If there was a way to do it, it would be in either of the current CSS selectors specs:

Selectors Level 3 Spec

CSS 2.1 Selectors Spec

That said, the Selectors Level 4 Working Draft includes a :has() pseudo-class that will provide this capability. It will be similar to the jQuery implementation.

li:has(> a.active) { /* styles to apply to the li tag */ }

However, as of 2022, it is only supported by Safari.

In the meantime, you'll have to resort to JavaScript if you need to select a parent element.

Yes: :has()

Browser support: Safari by default; Chrome (behind a flag)


As @Rodolfo Jorge Nemer Nogueira pointed out, it is possible with sass (scss) by using the & sign. That then gets compiled to the desired css. It would be nice if the next css version supported &
Actually, I think there is experimental syntax equivalent to Andrew's statement: @supports selector(:has(a))
@TamusJRoyce ... and what does SASS compile the resultant CSS too? It has to use CSS at the end of the day.
@Yukulélé Edits should improve posts. Changing "Safari only" to "low" is making the answer less clear by requiring the user to click-through to the link to see what "low" means. Stating "Safari only" tells readers exactly what they need to know without having to click the link and leave the site to find out what the answer means.

I don’t think you can select the parent in CSS only.

But as you already seem to have an .active class, it would be easier to move that class to the li (instead of the a). That way you can access both the li and the a via CSS only.


You can't shift the pseudo selector to the list item, as it is not a focusable element. He's using the :active selector, so when the anchor is active he wants the list item to be affected. List items will never be in the active state. As an aside, it's unfortunate that such a selector doesn't exist. Getting a pure CSS menu to be fully keyboard accessible seems to be impossible without it (using sibling selectors you can make submenus created using nested lists to appear, but once the list gains focus it becomes hidden again). If there are any CSS-only solutions to this particular conun
@Dominic Aquilina Take a look at the question, the OP is using a class, not a pseudo selector.

You can use this script:

*! > input[type=text] { background: #000; }

This will select any parent of a text input. But wait, there's still much more. If you want, you can select a specified parent:

.input-wrap! > input[type=text] { background: #000; }

Or select it when it's active:

.input-wrap! > input[type=text]:focus { background: #000; }

Check out this HTML:

<div class="input-wrap">
    <input type="text" class="Name"/>
    <span class="help hide">Your name sir</span>
</div>

You can select that span.help when the input is active and show it:

.input-wrap! .help > input[type=text]:focus { display: block; }

There are many more capabilities; just check out the documentation of the plugin.

BTW, it works in Internet Explorer.


suppose using jquery patent() would be faster. This need testing, however
@Idered It fails when you have CSS declaration of a Selector Subject with no child selector (#a! alone throws an error, #a! p works), and so the others will not works either because of Uncaught TypeError: Cannot call method 'split' of undefined: see jsfiddle.net/HerrSerker/VkVPs
@HerrSerker I think #a! is an invalid selector, what should it select?
@Idered I don't know. The spec doesn't say it is illegal. #a! should select itself. At least their should be no error in the JavaScript
Per my comment on the accepted answer, it looks like the polyfill may be required even in the near future after all, because the subject indicator may never be implemented by browsers in CSS.

As mentioned by a couple of others, there isn't a way to style an element's parent/s using just CSS but the following works with jQuery:

$("a.active").parents('li').css("property", "value");

The < selector does not exist (verified using jQuery 1.7.1).
Perhaps that <-syntax worked in 2009 but I've updated it (for 2013).
Even better, use jQuery's built-in :has() selector: $("li:has(a.active)").css("property", "value");. It reads similarly to CSS 4's proposed ! selector. See also: :parent selector, .parents() method, .parent() method.
And rather than using .css("property", "value") to style the selected elements, you should usually .addClass("someClass") and have in your CSS .someClass { property: value } (via). That way, you can notate the style with the full power of CSS and any preprocessors you are using.

There is no parent selector; just the way there is no previous sibling selector. One good reason for not having these selectors is because the browser has to traverse through all children of an element to determine whether or not a class should be applied. For example, if you wrote:

body:contains-selector(a.active) { background: red; }

Then the browser will have to wait until it has loaded and parsed everything until the </body> to determine if the page should be red or not.

The article Why we don't have a parent selector explains it in detail.


so make the browser faster. the internet itself faster. this selector is definitely needed, and the reason for not implementing it is, sadly, because we live in a slow, primitive world.
actually, the selector would make a very fast browser look slow.
I trust that browser developers would come up with an implementation which is (at least) as fast as the javascript version, which is the one people end up using anyway.
@Marc.2377 If you try the above example in JS on your website, I'm never going to visit it. On the other side, I'd say that most of the time, you only care about immediate children, so if it was only limited to the immediate children, it'd be a good addition without too much impact.

Peter Mortensen

There isn't a way to do this in CSS 2. You could add the class to the li and reference the a:

li.active > a {
    property: value;
}

by making the a element display:block you can style it to fit the whole of the li area. if you can explain what style you are looking for perhaps I could help with a solution.

The pseudo element :focus-within allows a parent to be selected if a descendent has focus.

An element can be focused if it has a tabindex attribute.

Browser support for focus-within

Tabindex

Example

.parent:focus-within { background: hsl(199deg, 65%, 73%); } /* demo styles */ body { margin: 0; } .parent { background: hsl(0, 0%, 80%); min-height: 100vh; display: grid; place-content: center; } .child { background: hsl(0, 0%, 0%); color: white; padding: 3rem; outline: 0; cursor: pointer; font: 18px/1.25 sans-serif; width: 20ch; }

Click or Focus on me, my parent will change.


This works fine in my case, thanks! Just a not, the example would be more ilustrative if you change the color to the parent, not to the sibling, this is replace .color:focus-within .change with .color:focus-within. In my case i'm using bootstrap nav-bar that add the class to the children when active and I want to add a class to the parent .nav-bar. I think this is a pretty common scenario where I own the markup but the component css+js is bootstrap (or other) so I cannot change the behavior. Although I can add tabindex and use this css. Thanks!

Peter Mortensen

Try to switch a to block display, and then use any style you want. The a element will fill the li element, and you will be able to modify its look as you want. Don't forget to set li padding to 0.

li {
  padding: 0;
  overflow: hidden;
}
a {
  display: block;
  width: 100%;
  color: ..., background: ..., border-radius: ..., etc...
}
a.active {
  color: ..., background: ...
}

The CSS selector “General Sibling Combinator” could maybe used for what you want:

E ~ F {
    property: value;
}

This matches any F element that is preceded by an E element.


.component-one:visible ~ body{ background-color: red; } does not work.
@F-Natic I am not surprised that does not work. It is not valid CSS (there is no :visible pseudo-class in CSS). body is also a direct and only descendant of html.

Not in CSS 2 as far as I'm aware. CSS 3 has more robust selectors but is not consistently implemented across all browsers. Even with the improved selectors, I don't believe it will accomplish exactly what you've specified in your example.

I know the OP was looking for a CSS solution but it is simple to achieve using jQuery. In my case I needed to find the <ul> parent tag for a <span> tag contained in the child <li>. jQuery has the :has selector so it's possible to identify a parent by the children it contains:

$("ul:has(#someId)")

will select the ul element that has a child element with id someId. Or to answer the original question, something like the following should do the trick (untested):

$("li:has(.active)")

Or use $yourSpan.closest("ul") and you'll get the parent UL of your span element. Nevertheless your answer is completely offtopic imho. We can answer all of the CSS-taged questions with a jQuery solution.

This is the most discussed aspect of the Selectors Level 4 specification. With this, a selector will be able to style an element according to its child by using an exclamation mark after the given selector (!).

For example:

body! a:hover{
   background: red;
}

will set a red background-color if the user hovers over any anchor.

But we have to wait for browsers' implementation :(


The ("!") feature has been replaced with ':has()' drafts.csswg.org/selectors/#changes-2013

You might try to use hyperlink as the parent, and then change the inner elements on hover. Like this:

a.active h1 {color:red;}

a.active:hover h1 {color:green;}

a.active h2 {color:blue;}

a.active:hover h1 {color:yellow;}

This way you can change the style in multiple inner tags, based on the rollover of the parent element.


That is correct, but limits the markup code within the a tag to certain elements only, if you want to conform to XHTML standards. For instance, you cannot use a div within a, without getting a warning of violating the schema.
Totaly right Ivaylo! "a" is a non-block element, so can't use block elements inside it.
In HTML5 it is perfectly fine to put block elements inside links.
... if it was semantically wrong, they wouldn't have allowed it in HTML5 where it wasn't before.
@BoltClock replying from the distant future admittedly, but I suspect Matthew's comment about HTML5 was more to contrast "HTML" with "XHTML" (where it isn't allowed, according to Ivaylo/riverstorm), not to contrast HTML 5 with prior versions of HTML.

Currently there is no parent selector & it is not even being discussed in any of the talks of W3C. You need to understand how CSS is evaluated by the browser to actually understand if we need it or not.

There is a lot of technical explanation here.

Jonathan Snook explains how CSS is evaluated.

Chris Coyier on the talks of Parent selector.

Harry Roberts again on writing efficient CSS selectors.

But Nicole Sullivan has some interesting facts on positive trends.

These people are all top class in the field of front end development.


The need is defined by web developers' requirements, whether to have it in the spec is decided by other factors.

Just an idea for horizontal menu...

Part of HTML

<div class='list'>
  <div class='item'>
    <a>Link</a>
  </div>
  <div class='parent-background'></div>
  <!-- submenu takes this place -->
</div>

Part of CSS

/* Hide parent backgrounds... */
.parent-background {
  display: none; }

/* ... and show it when hover on children */
.item:hover + .parent-background {
  display: block;
  position: absolute;
  z-index: 10;
  top: 0;
  width: 100%; }

Updated demo and the rest of code

Another example how to use it with text-inputs - select parent fieldset


It's not at all clear to me how you mean to generalize this to some/many/most of the parent selector use cases, or even exactly which parts of this CSS are doing what. Can you add a thorough explanation?
I did not try to apply this to real world scenarios, that is why I say "Not for production". But I think It can be applied to 2-level menu only with fixed item width. "which parts of this CSS are doing what" - .test-sibling here is actually background of parent item (the last line of CSS).
Added explanation (css section of jsfiddle, starting from "MAIN PART")... And I was mistaken - there may be any number of sublevels.

There's a plugin that extends CSS to include some non-standard features that can really help when designing websites. It's called EQCSS.

One of the things EQCSS adds is a parent selector. It works in all browsers, Internet Explorer 8 and up. Here's the format:

@element 'a.active' {
  $parent {
    background: red;
  }
}

So here we've opened an element query on every element a.active, and for the styles inside that query, things like $parent make sense, because there's a reference point. The browser can find the parent, because it's very similar to parentNode in JavaScript.

Here's a demo of $parent and another $parent demo that works in Internet Explorer 8, as well as a screenshot in case you don't have Internet Explorer 8 around to test with.

EQCSS also includes meta-selectors: $prev for the element before a selected element and $this for only those elements that match an element query, and more.

It's now 2019, and the latest draft of the CSS Nesting Module actually has something like this. Introducing @nest at-rules.

3.2. The Nesting At-Rule: @nest While direct nesting looks nice, it is somewhat fragile. Some valid nesting selectors, like .foo &, are disallowed, and editing the selector in certain ways can make the rule invalid unexpectedly. As well, some people find the nesting challenging to distinguish visually from the surrounding declarations. To aid in all these issues, this specification defines the @nest rule, which imposes fewer restrictions on how to validly nest style rules. Its syntax is: @nest = @nest { } The @nest rule functions identically to a style rule: it starts with a selector, and contains declarations that apply to the elements the selector matches. The only difference is that the selector used in a @nest rule must be nest-containing, which means it contains a nesting selector in it somewhere. A list of selectors is nest-containing if all of its individual complex selectors are nest-containing.

(Copy and pasted from the URL above).

Example of valid selectors under this specification:

.foo {
  color: red;
  @nest & > .bar {
    color: blue;
  }
}
/* Equivalent to:
   .foo { color: red; }
   .foo > .bar { color: blue; }
 */

.foo {
  color: red;
  @nest .parent & {
    color: blue;
  }
}
/* Equivalent to:
   .foo { color: red; }
   .parent .foo { color: blue; }
 */

.foo {
  color: red;
  @nest :not(&) {
    color: blue;
  }
}
/* Equivalent to:
   .foo { color: red; }
   :not(.foo) { color: blue; }
 */

The W3C excluded such a selector because of the huge performance impact it would have on a browser.


false. because the DOM is a tree, they have to go to the parent before getting to the child, so the simply just go back one node. o.o
CSS selectors are a queue so selector order is evaluated rather than the document XPath or DOM hierarchy.
@rgb At least that's what they told us.

Peter Mortensen

Technically there is no direct way to do this. However, you can sort that out with either jQuery or JavaScript.

However, you can do something like this as well.

a.active h1 {color: blue;}
a.active p {color: green;}

jQuery

$("a.active").parents('li').css("property", "value");

If you want to achieve this using jQuery here is the reference for the jQuery parent selector.


P
Peter Mortensen

The short answer is NO; we don't have a parent selector at this stage in CSS, but if you don't have to swap the elements or classes anyway, the second option is using JavaScript. Something like this:

var activeATag = Array.prototype.slice.call(document.querySelectorAll('a.active'));

activeATag.map(function(x) {
  if(x.parentNode.tagName === 'LI') {
    x.parentNode.style.color = 'red'; // Your property: value;
  }
});

Or a shorter way if you use jQuery in your application:

$('a.active').parents('li').css('color', 'red'); // Your property: value;

or parentElement, sameshing - just document.getElementById().parentElement etc.

Although there is no parent selector in standard CSS at present, I am working on a (personal) project called axe (ie. Augmented CSS Selector Syntax / ACSSSS) which, among its 7 new selectors, includes both:

an immediate parent selector < (which enables the opposite selection to >) an any ancestor selector ^ (which enables the opposite selection to [SPACE])

axe is presently in a relatively early BETA stage of development.

See a demo here:

.parent { float: left; width: 180px; height: 180px; margin-right: 12px; background-color: rgb(191, 191, 191); } .child { width: 90px; height: 90px; margin: 45px; padding-top: 12px; font-family: sans-serif; text-align: center; font-size: 12px; background-color: rgb(255, 255, 0); } .child.using-axe < .parent { background-color: rgb(255, 0, 0); }

Here, the axe parent selector turns the outer square red.

In the example above < is the immediate parent selector, so

.child.using-axe < .parent

means:

any immediate parent of .child.using-axe which is .parent

You could alternatively use:

.child.using-axe < div

which would mean:

any immediate parent of .child.using-axe which is a div


The project is in an early Beta stage at present. You can (at least currently) activate axe selectors in your CSS styles by including <script src="https://rouninmedia.github.io/axe/axe.js"></script> at the very end of your html document, just before </body>.

The CSS parent selector (also know as the :has() selector) has finally landed in Safari TP 137. The feature is currently being implementated in Chrome as well. (MDN Documentation)

Parent selection is done via the pseudo-class :has(). For example, div:has(> .child) will select all <div> elements with a child having a child class.

Other examples:

Selecting direct parent of an element

<div>
  <p>Child Element</p>
</div>
div:has(> p)

Selecting all the parents of an element

<div id="grandparent">
      <div id="parent">
            <div id="child"></div>
      <div>
</div>

The following selector will select both grandparent and parent

div:has(.child)

You can also use it for nested selectors and even with other pseudo classes:

div:has(> :nth-child(10))

Other valid CSS operators can be used to customize the query.

Keep an eye on caniuse.com/css-has for browser compatibility.

Peter Mortensen

At least up to and including CSS 3 you cannot select like that. But it can be done pretty easily nowadays in JavaScript, you just need to add a bit of vanilla JavaScript, notice that the code is pretty short.

cells = document.querySelectorAll('div'); [].forEach.call(cells, function (el) { //console.log(el.nodeName) if (el.hasChildNodes() && el.firstChild.nodeName=="A") { console.log(el) }; });

Changing parent element based on child element can currently only happen when we have an <input> element inside the parent element. When an input gets focus, its corresponding parent element can get affected using CSS.

Following example will help you understand using :focus-within in CSS.

.outer-div { width: 400px; height: 400px; padding: 50px; float: left } .outer-div:focus-within { background: red; } .inner-div { width: 200px; height: 200px; float: left; background: yellow; padding: 50px; }

I want to change outer-div(Background color) class based on inner-div. Is it possible?


The :focus-within CSS pseudo-class matches an element if the element or any of its descendants are focused. It works with every element, not just input
P
Peter Mortensen

No, you cannot select the parent in CSS only.

But as you already seem to have an .active class, it would be easier to move that class to the li (instead of the a). That way you can access both the li and the a via CSS only.

Any ideas?

CSS4 will be fancy if it adds some hooks into walking backwards. Until then it is possible (though not advisable) to use checkbox and/or radio inputs to break the usual way that things are connected, and through that also allow CSS to operate outside of its normal scope...

/* Hide things that may be latter shown */ .menu__checkbox__selection, .menu__checkbox__style, .menu__hidden { display: none; visibility: hidden; opacity: 0; filter: alpha(opacity=0); /* Old Microsoft opacity */ } /* Base style for content and style menu */ .main__content { background-color: lightgray; color: black; } .menu__hidden { background-color: black; color: lightgray; /* Make list look not so _listy_ */ list-style: none; padding-left: 5px; } .menu__option { box-sizing: content-box; display: block; position: static; z-index: auto; } /* ▼ - \u2630 - Three Bars */ /* .menu__trigger__selection::before { content: '\2630'; display: inline-block; } */ /* ▼ - Down Arrow */ .menu__trigger__selection::after { content: "\25BC"; display: inline-block; transform: rotate(90deg); } /* Customize to look more `select` like if you like */ .menu__trigger__style:hover, .menu__trigger__style:active { cursor: pointer; background-color: darkgray; color: white; } /** * Things to do when checkboxes/radios are checked */ .menu__checkbox__selection:checked + .menu__trigger__selection::after, .menu__checkbox__selection[checked] + .menu__trigger__selection::after { transform: rotate(0deg); } /* This bit is something that you may see elsewhere */ .menu__checkbox__selection:checked ~ .menu__hidden, .menu__checkbox__selection[checked] ~ .menu__hidden { display: block; visibility: visible; opacity: 1; filter: alpha(opacity=100); /* Microsoft!? */ } /** * Hacky CSS only changes based off non-inline checkboxes * ... AKA the stuff you cannot unsee after this... */ .menu__checkbox__style[id="style-default"]:checked ~ .main__content { background-color: lightgray; color: black; } .menu__checkbox__style[id="style-default"]:checked ~ .main__content .menu__trigger__style[for="style-default"] { color: darkorange; } .menu__checkbox__style[id="style-one"]:checked ~ .main__content { background-color: black; color: lightgray; } .menu__checkbox__style[id="style-one"]:checked ~ .main__content .menu__trigger__style[for="style-one"] { color: darkorange; } .menu__checkbox__style[id="style-two"]:checked ~ .main__content { background-color: darkgreen; color: red; } .menu__checkbox__style[id="style-two"]:checked ~ .main__content .menu__trigger__style[for="style-two"] { color: darkorange; }

... pretty gross, but with just CSS and HTML it is possible to touch and re-touch anything but the body and :root from just about anywhere by linking the id and for properties of radio/checkbox inputs and label triggers; likely someone'll show how to re-touch those at some point.

One additional caveat is that only one input of a specific id maybe used, first checkbox/radio wins a toggled state in other words... But multiple labels can all point to the same input, though that would make both the HTML and CSS look even grosser.

... I'm hoping that there is some sort of workaround that exists native to CSS Level 2...

I am not sure about the other pseudo classes, but I :checked for pre-CSS 3. If I remember correctly, it was something like [checked] which is why you may find it in the above code, for example,

.menu__checkbox__selection:checked ~ .menu__hidden,
.menu__checkbox__selection[checked] ~ .menu__hidden {
 /* rules: and-stuff; */
}

... but for things like ::after and :hover, I'm not at all certain in which CSS version those first appeared.

That all stated, please don't ever use this in production, not even in anger. As a joke sure, or in other words just because something can be done does not always mean it should.


There has never been a "CSS4" planned, and even CSS3 had been merged into just "CSS" well before 2019.
Tyler CSS4 is being considered by those that maintain the spec. Announcement link → w3.org/community/css4 Discussion link → github.com/w3c/csswg-drafts/issues/4770
That's just the name of a discussion group. There will be no technology called CSS4. CSS Modules are versioned independently and have been for many years now. As the actual CSSWG contributors in that random user's GitHub request have already replied and wrote a response about, it's not a good idea. Plus that request has been dead for over a year (you can see the GH w3c account has been deleting recent advocacy comments trying to necro it).
That article is an opinion peace, and overall is a distraction from the spec discussion thread. A handful of off-topic marked comments and one deleted comment does not make intent to necro, and I'd expect the Issue to be marked as Closed if the working group where committed to killing CSS4 discussion. It's okay, and a good thing in large projects, that modules are versioned independently; module versions do not conflict with spec versioning.
It's an opinion piece by a contributing member of the CSSWG extrapolating on her "no" response in the GitHub request, which has languages inactive for over a year. It's safe to say it is not being moved forward with. Module versions would conflict massively with spec versioning, as several comments in the thread highlight. Listen, as badly as you want it to be a thing, it's not. It's important to accept that and not confuse readers by mentioning things that don't exist.

Try this...

This solution uses plain CSS2 rules with no Javascript and works in all browsers, old and new. When clicked, the child anchor tag activates its active pseudo-class event. It then simply hides itself, allowing the active event to bubble up to the parent li tag who then restyles himself and reveals his anchor child again with a new style. The child has styled the parent.

Using your example:

<ul>
    <li class="listitem">
        <a class="link" href="#">This is a Link</a>
    </li>
</ul>

Now apply these styles with the active pseudo-class on a to restyle the parent li tag when the link is clicked:

a.link {
    display: inline-block;
    color: white;
    background-color: green;
    text-decoration: none;
    padding: 5px;
}

li.listitem {
    display: inline-block;
    margin: 0;
    padding: 0;
    background-color: transparent;
}

/* When this 'active' pseudo-class event below fires on click, it hides itself,
triggering the active event again on its parent which applies new styles to itself and its child. */

a.link:active {
    display: none;
}

.listitem:active {
    background-color: blue;
}

.listitem:active a.link {
    display: inline-block;
    background-color: transparent;
}

You should see the link with a green background now change to the list item's blue background on click.

There no css (and therefore in css preprocessors) parent selector due to "The major reasons for the CSS Working Group previously rejecting proposals for parent selectors are related to browser performance and incremental rendering issues."
