Twitter Bootstrap - add top space between rows

Editing or overriding the row in Twitter bootstrap is a bad idea, because this is a core part of the page scaffolding and you will need rows without a top margin.

To solve this, instead create a new class "top-buffer" that adds the standard margin that you need.

.top-buffer { margin-top:20px; }

And then use it on the row divs where you need a top margin.

<div class="row top-buffer"> ...

Ok just to let you know what's happened then, i fixed using some new classes as Acyra says above:

.top5 { margin-top:5px; }
.top7 { margin-top:7px; }
.top10 { margin-top:10px; }
.top15 { margin-top:15px; }
.top17 { margin-top:17px; }
.top30 { margin-top:30px; }

whenever i want i do <div class="row top7"></div>

for better responsive you can add margin-top:7% instead of 5px for example :D

Bootstrap 3

If you need to separate rows in bootstrap, you can simply use .form-group. This adds 15px margin to the bottom of row.

In your case, to get margin top, you can add this class to previous .row element

<div class="row form-group">

/* From bootstrap.css */
.form-group {
        margin-bottom: 15px;
}

Bootstrap 4

You can use built-in spacing classes

<div class="row mt-3"></div>

The "t" in class name makes it apply only to "top" side, there are similar classes for bottom, left, right. The number defines space size.

---

For Bootstrap 4 spacing should be applied using

shorthand utility classes

in the following format:

{property}{sides}-{size}

Where property is one of:

m - for classes that set margin

p - for classes that set padding

Where sides is one of:

t - for classes that set margin-top or padding-top

b - for classes that set margin-bottom or padding-bottom

l - for classes that set margin-left or padding-left

r - for classes that set margin-right or padding-right

x - for classes that set both *-left and *-right

y - for classes that set both *-top and *-bottom

blank - for classes that set a margin or padding on all 4 sides of the element

Where size is one of:

0 - for classes that eliminate the margin or padding by setting it to 0

1 - (by default) for classes that set the margin or padding to $spacer * .25

2 - (by default) for classes that set the margin or padding to $spacer * .5

3 - (by default) for classes that set the margin or padding to $spacer

4 - (by default) for classes that set the margin or padding to $spacer * 1.5

5 - (by default) for classes that set the margin or padding to $spacer * 3

auto - for classes that set the margin to auto

So you should be doing any of these:

<div class="row mt-1">
<div class="row mt-2">
          ...
<div class="row mt-5">

Read the docs for more explanation. Try live examples over here.

Sometimes margin-top can causes design problems:

http://www.w3.org/TR/CSS2/box.html#collapsing-margins

So, i recommend create "margin-bottom classes" instead of "margin-top classes" and apply them to the previous item.

If you are using Bootstrap importing LESS Bootstrap files try to define the margin-bottom classes with proportional Bootstrap Theme spaces:

.margin-bottom-xs {margin-bottom: ceil(@line-height-computed / 4);}  
.margin-bottom-sm {margin-bottom: ceil(@line-height-computed / 2);} 
.margin-bottom-md {margin-bottom: @line-height-computed;}
.margin-bottom-lg {margin-bottom: ceil(@line-height-computed * 2);}  

---

I added these classes to my bootstrap stylesheet

.voffset  { margin-top: 2px; }
.voffset1 { margin-top: 5px; }
.voffset2 { margin-top: 10px; }
.voffset3 { margin-top: 15px; }
.voffset4 { margin-top: 30px; }
.voffset5 { margin-top: 40px; }
.voffset6 { margin-top: 60px; }
.voffset7 { margin-top: 80px; }
.voffset8 { margin-top: 100px; }
.voffset9 { margin-top: 150px; }

Example

<div class="container">
  <div class="row voffset2">
    <div class="col-lg-12">
      <p>
        Vertically offset text.
      </p>
    </div>
  </div>
</div>

I'm using these classes to alter top margin:

.margin-top-05 { margin-top: 0.5em; }
.margin-top-10 { margin-top: 1.0em; }
.margin-top-15 { margin-top: 1.5em; }
.margin-top-20 { margin-top: 2.0em; }
.margin-top-25 { margin-top: 2.5em; }
.margin-top-30 { margin-top: 3.0em; }

When I need an element to have 2em spacing from the element above I use it like this:

<div class="row margin-top-20">Something here</div>

If you prefere pixels so change the em to px to have it your way.

You can use the following class for bootstrap 4:

mt-0 mt-1 mt-2 mt-3 mt-4 ...

Ref: https://v4-alpha.getbootstrap.com/utilities/spacing/

---

Bootstrap 4 alpha, for margin-top: shorthand CSS class names mt-1, mt-2 ( mt-lg-5, mt-sm-2) same for the bottom, right, left, and you have also auto class ml-auto

    <div class="mt-lg-1" ...>

Units are from 1 to 5 : in the variables.scss which means if you set mt-1 it gives .25rem of margin top.

$spacers: (
  0: (
    x: 0,
    y: 0
  ),
  1: (
    x: ($spacer-x * .25),
    y: ($spacer-y * .25)
  ),
  2: (
    x: ($spacer-x * .5),
    y: ($spacer-y * .5)
  ),
  3: (
    x: $spacer-x,
    y: $spacer-y
  ),
  4: (
    x: ($spacer-x * 1.5),
    y: ($spacer-y * 1.5)
  ),
  5: (
    x: ($spacer-x * 3),
    y: ($spacer-y * 3)
  )
) !default;

Add to this class in the .css file:

.row {
    margin-left: -20px;
    *zoom: 1;
    margin-top: 50px;
}

or make a new class and add it to the element

.rowSpecificFormName td {
    margin-top: 50px;
}

---

If you want to change just on one page, add the following style rule:

 #myCustomDivID .row {
     margin-top:20px;
 }

---

In Bootstrap 4 alpha+ you can use this

class margin-bottom-5

The classes are named using the format: {property}-{sides}-{size}

---

just take a new class beside every row and apply css of margin-top: 20px;
here is the code below
<style>
  .small-top
   {
     margin-top: 25px;  
   }
</style>    
<div class="row small-top">
   <div class="col-md-12">
   </div>
 </div>

Bootstrap3

CSS (gutter only, without margins around):

.row.row-gutter {
  margin-bottom: -15px;
  overflow: hidden;
}
.row.row-gutter > *[class^="col"] {
  margin-bottom: 15px;
}

CSS (equal margins around, 15px/2):

.row.row-margins {
  padding-top: 7px; /* or margin-top: 7px; */
  padding-bottom: 7px; /* or margin-bottom: 7px; */
}
.row.row-margins > *[class^="col"] {
  margin-top: 8px;
  margin-bottom: 8px;
}

Usage:

<div class="row row-gutter">
    <div class="col col-sm-9">first</div>
    <div class="col col-sm-3">second</div>
    <div class="col col-sm-12">third</div>
</div>

(with SASS or LESS 15px could be a variable from bootstrap)

<div class="row row-padding">

simple code

There is a trick for adding margin automatically only for the 2nd+ row in the container.

.container-row-margin .row + .row {
    margin-top: 1rem;
}

Adding the .container-row-margin to the container, results in:

https://i.stack.imgur.com/Yfq1C.png

Complete HTML:

<div class="bg-secondary text-white">
    div outside of the container.
</div>
<div class="container container-row-margin">
    <div class="row">
        <div class="col col-4 bg-warning">
            Row without top margin
        </div>
    </div>
    <div class="row">
        <div class="col col-4 bg-primary text-white">
            Row with top margin
        </div>
    </div>
    <div class="row">
        <div class="col col-4 bg-primary text-white">
            Row with top margin
        </div>
    </div>
</div>
<div class="bg-secondary text-white">
    div outside of the container.
</div>

Taken from official samples.

you can add this code :

[class*="col-"] {
    padding-top: 1rem;
    padding-bottom: 1rem;
}

Just simply use this bs3-upgrade helper for spacings and text aligment...

https://github.com/studija/bs3-upgrade

If you're using BootStrap 3.3.7, you can use the open source library bootstrap-spacer via NPM

npm install bootstrap-spacer

or you can visit the github page:

https://github.com/chigozieorunta/bootstrap-spacer

Here's an example of how this works to space rows using the .row-spacer class:

<div class="row row-spacer">
    <div class="col-md-4">
    </div>
    <div class="col-md-4">
    </div>
    <div class="col-md-4">
    </div>
</div>

<div class="row row-spacer">
    <div class="col-md-4">
    </div>
    <div class="col-md-4">
    </div>
    <div class="col-md-4">
    </div>
</div>

If you'd require spaces between columns, you can also add the .row-col-spacer class:

<div class="row row-col-spacer">
    <div class="col-md-4">
    </div>
    <div class="col-md-4">
    </div>
    <div class="col-md-4">
    </div>
</div>

And you can also combine various the .row-spacer & .row-col-spacer classes together:

<div class="row row-spacer row-col-spacer">
    <div class="col-md-4">
    </div>
    <div class="col-md-4">
    </div>
    <div class="col-md-4">
    </div>
</div>

My trick. Not so clean, but works well for me
