How do I position one image on top of another in HTML?

Ok, after some time, here's what I landed on:

.parent { position: relative; top: 0; left: 0; } .image1 { position: relative; top: 0; left: 0; border: 1px red solid; } .image2 { position: absolute; top: 30px; left: 30px; border: 1px green solid; }

As the simplest solution. That is:

Create a relative div that is placed in the flow of the page; place the base image first as relative so that the div knows how big it should be; place the overlays as absolutes relative to the upper left of the first image. The trick is to get the relatives and absolutes correct.

This is a barebones look at what I've done to float one image over another.

img { position: absolute; top: 25px; left: 25px; } .imgA1 { z-index: 1; } .imgB1 { z-index: 3; }

Here's code that may give you ideas:

<style>
.containerdiv { float: left; position: relative; } 
.cornerimage { position: absolute; top: 0; right: 0; } 
</style>

<div class="containerdiv">
    <img border="0" src="https://www.google.com/images/branding/googlelogo/2x/googlelogo_color_272x92dp.png" alt=""">
    <img class="cornerimage" border="0" src="http://www.gravatar.com/avatar/" alt="">
<div>

JSFiddle

I suspect that Espo's solution may be inconvenient because it requires you to position both images absolutely. You may want the first one to position itself in the flow.

Usually, there is a natural way to do that is CSS. You put position: relative on the container element, and then absolutely position children inside it. Unfortunately, you cannot put one image inside another. That's why I needed container div. Notice that I made it a float to make it autofit to its contents. Making it display: inline-block should theoretically work as well, but browser support is poor there.

EDIT: I deleted size attributes from the images to illustrate my point better. If you want the container image to have its default sizes and you don't know the size beforehand, you cannot use the background trick. If you do, it is a better way to go.

One issue I noticed that could cause errors is that in rrichter's answer, the code below:

<img src="b.jpg" style="position: absolute; top: 30; left: 70;"/>

should include the px units within the style eg.

<img src="b.jpg" style="position: absolute; top: 30px; left: 70px;"/>

Other than that, the answer worked fine. Thanks.

You can absolutely position pseudo elements relative to their parent element.

This gives you two extra layers to play with for every element - so positioning one image on top of another becomes easy - with minimal and semantic markup (no empty divs etc).

markup:

<div class="overlap"></div>

css:

.overlap
{
    width: 100px;
    height: 100px;
    position: relative;
    background-color: blue;
}
.overlap:after
{
    content: '';
    position: absolute;
    width: 20px;
    height: 20px;
    top: 5px;
    left: 5px;
    background-color: red;
}

Here's a LIVE DEMO

It may be a little late but for this you can do:

HTML

<!-- html -->
<div class="images-wrapper">
  <img src="images/1" alt="image 1" />
  <img src="images/2" alt="image 2" />
  <img src="images/3" alt="image 3" />
  <img src="images/4" alt="image 4" />
</div>

SASS

// In _extra.scss
$maxImagesNumber: 5;

.images-wrapper {
  img {
    position: absolute;
    padding: 5px;
    border: solid black 1px;
  }

  @for $i from $maxImagesNumber through 1 {
    :nth-child(#{ $i }) {
      z-index: #{ $maxImagesNumber - ($i - 1) };
      left: #{ ($i - 1) * 30 }px;
    }
  }
}

Inline style only for clarity here. Use a real CSS stylesheet.

<!-- First, your background image is a DIV with a background 
     image style applied, not a IMG tag. -->
<div style="background-image:url(YourBackgroundImage);">
    <!-- Second, create a placeholder div to assist in positioning 
         the other images. This is relative to the background div. -->
    <div style="position: relative; left: 0; top: 0;">
        <!-- Now you can place your IMG tags, and position them relative 
             to the container we just made -->   
        <img src="YourForegroundImage" style="position: relative; top: 0; left: 0;"/>
    </div>
</div>

The easy way to do it is to use background-image then just put an in that element.

The other way to do is using css layers. There is a ton a resources available to help you with this, just search for css layers.

You could use CSS-Grid, which is a very convenient solution if you want to stack, overlap content. First you need to define your grid. Inside that grid, you "tell" your img-tags where to be places within that grid. If you define them to be at the same start of the grid, they will be overlapped. In the following example two images are overlapped, one is below them.

You can find a very good explanation of CSS-Grid here.

Set background-size cover. Then wrap your div with another div now set max-width on parent div.

<div style="max-width:100px">
  <div style="background-image:url('/image.png'); background-size: cover; height:100px; width:100px; "></div>
</div>

Here is a solution that worked for me. Assuming all the images to be stacked are inside a div container, all you need to do is to set the display property of the div to flex. Don't set any position for the first image but for every other image, set the position property to absolute. Finally, use z-index to control the layers. You can set the first image's z-index to 1, the second image's z-index to 2, and so on (In my own case, I set the z-index of every other image apart from the first image to 2). If you want to center the images, you can set the justify-content property of the div to center to align the images horizontally to the center and adjust the top property to align the images vertically to the center. The values you use for the justify-content and top properties depend on the size of your images and whether the sizes are responsive on different devices or not. Here's my example:

img { border: 2px solid red; } .img1n2 { display: flex; justify-content:center; } .img1 { z-index: 1; } .img2 { position: absolute; z-index: 2; top: 52.5%; }

You can actually stack a thousand or a million images with this method. You can play around with the CSS to suit your specific needs. Happy coding!

@buti-oxa: Not to be pedantic, but your code is invalid. The HTML width and height attributes do not allow for units; you're likely thinking of the CSS width: and height: properties. You should also provide a content-type (text/css; see Espo's code) with the <style> tag.

<style type="text/css"> 
.containerdiv { float: left; position: relative; } 
.cornerimage { position: absolute; top: 0; right: 0; } 
</style>

<div class="containerdiv">
    <img border="0" src="http://www.gravatar.com/avatar/" alt="" width="100" height="100">
    <img class="cornerimage" border="0" src="http://www.gravatar.com/avatar/" alt="" width="40" height="40">
<div>

Leaving px; in the width and height attributes might cause a rendering engine to balk.

Create a relative div that is placed in the flow of the page; place the base image first as relative so that the div knows how big it should be; place the overlays as absolutes relative to the upper left of the first image. The trick is to get the relatives and absolutes correct.
