Center a column using Twitter Bootstrap

How do I center a div of one column size within the container (12 columns) in Twitter Bootstrap 3?

.centered {
  background-color: red;
}
<!-- Latest compiled and minified CSS -->
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css" integrity="sha384-BVYiiSIFeK1dGmJRAkycuHAHRg32OmUcww7on3RYdg4Va+PmSTsz/K68vbdEjh4u" crossorigin="anonymous">

<body class="container">
  <div class="col-lg-1 col-offset-6 centered">
    <img data-src="holder.js/100x100" alt="" />
  </div>
</body>

I want a div, with a class .centered to be centered within the container. I may use a row if there are multiple divs, but for now I just want a div with the size of one column centered within the container (12 columns).

I am also not sure the above approach is good enough as the intention is not to offset the div by half. I do not need free spaces outside the div and the contents of the div shrink in proportion. I want to empty space outside the div to be evenly distributed (shrink till the container width is equal to one column).

Bootstrap 5 (update 2023)

Bootstrap 5 is also flexbox based so centering is similar to Bootstrap 4. Auto-margins can be used to push columns to the center...

<div class="row">
     <div class="col-3 mx-auto text-center border">
         <p>
            I'm centered (margin: auto)
         </p>
     </div>
</div>

-OR-

Use the flexbox utility classes (ie: justify-content-center) to center...

<div class="row justify-content-center">
        <div class="col-4 text-center border">
            <p>
                I'm centered
            </p>
        </div>
</div>

Bootstrap 4 (update 2020)

With flexbox based Bootstrap 4, the centering methods have changed..

  • text-center is still used for display:inline elements
  • mx-auto replaces center-block to center display:block elements
  • offset-* or mx-auto can be used to center grid columns

mx-auto (auto x-axis margins) will center display:block or display:flex elements that have a defined width, (%, vw, px, etc..). Flexbox is used by default on grid columns, so there are also various flexbox centering methods.

Demo Bootstrap 4 Horizontal Centering

For vertical centering in BS4 see https://stackoverflow.com/a/41464397/171456

Bootstrap 3 (original answer)

The preferred method of centering columns is to use "offsets" (ie: col-md-offset-3)

Bootstrap 3.x centering examples

For centering elements, there is a center-block helper class.

You can also use text-center to center text (and inline elements).

Responsive Demo: https://codeply.com/p/sRH9hSKup1

EDIT - As mentioned in the comments, center-block works on column contents and display:block elements, but won't work on the column itself (col-* divs) because Bootstrap uses float.

Another approach of offsetting is to have two empty columns, for example:

<div class="col-md-4"></div>
<div class="col-md-4">Centered Content</div>
<div class="col-md-4"></div>

With Bootstrap v3 and v4, this can be accomplished just by adding .justify-content-center to the .row <div>

<div class="row justify-content-center">
    <div class="col-1">centered 1 column</div>
</div>

With bootstrap 4 you can simply try justify-content-md-center as it is mentioned here

<div class="container">
    <div class="row justify-content-md-center">
        <div class="col col-lg-2">
              1 of 3
        </div>
        <div class="col-md-auto">
            Variable width content
        </div>
        <div class="col col-lg-2">
              3 of 3
        </div>
    </div>
    <div class="row">
        <div class="col">
             1 of 3
        </div>
        <div class="col-md-auto">
                Variable width content
        </div>
        <div class="col col-lg-2">
              3 of 3
        </div>
    </div>
</div>

Use mx-auto in your div class using Bootstrap 4.

<div class="container">
  <div class="row">
    <div class="mx-auto">
      You content here
    </div>
  </div>

Note if you are using Bootstrap 4, you can use .align-items-center in your row as Boostrap 4 now uses the flex system.

Try this code.

<body class="container">
    <div class="col-lg-1 col-lg-offset-10">
        <img data-src="holder.js/100x100" alt="" />
    </div>
</body>

Here I have used col-lg-1, and the offset should be 10 for properly centered the div on large devices. If you need it to center on medium-to-large devices then just change the lg to md and so on.

My approach to center columns is to use display: inline-block for columns and text-align: center for the container parent.

You just have to add the CSS class 'centered' to the row.

HTML:

<div class="container-fluid">
  <div class="row centered">
    <div class="col-sm-4 col-md-4">
        Col 1
    </div>
    <div class="col-sm-4 col-md-4">
        Col 2
    </div>
    <div class="col-sm-4 col-md-4">
        Col 3
    </div>
  </div>
</div>

CSS:

.centered {
   text-align: center;
   font-size: 0;
}
.centered > div {
   float: none;
   display: inline-block;
   text-align: left;
   font-size: 13px;
}

You can use text-center for the row and can make sure the internal divs have display:inline-block (with not float).

As:

<div class="container">
    <div class="row text-center" style="background-color : black;">
        <div class="redBlock">A red block</div>
        <div class="whiteBlock">A white block</div>
        <div class="yellowBlock">A yellow block</div>
    </div>
</div>

And CSS:

.redBlock {
    width: 100px;
    height: 100px;
    background-color: aqua;
    display: inline-block
}
.whiteBlock {
    width: 100px;
    height: 100px;
    background-color: white;
    display: inline-block
}
.yellowBlock {
    width: 100px;
    height: 100px;
    background-color: yellow;
    display: inline-block
}

Simply add the following to your custom CSS file. Editing Bootstrap CSS files directly is not recommended and cancels your ability to use a CDN.

.center-block {
    float: none !important
}

Why?

Bootstrap CSS (version 3.7 and lower) uses margin: 0 auto;, but it gets overridden by the float property of the size container.

PS:

After you add this class, don't forget to set classes by the right order.

<div class="col-md-6 center-block">Example</div>

There are two approaches to centering a column <div> in Bootstrap 3:

Approach 1 (offsets):

The first approach uses Bootstrap's own offset classes so it requires no change in markup and no extra CSS. The key is to set an offset equal to half of the remaining size of the row. So for example, a column of size 2 would be centered by adding an offset of 5, that's (12-2)/2.

In markup this would look like:

<div class="row">
    <div class="col-md-2 col-md-offset-5"></div>
</div>

Now, there's an obvious drawback for this method. It only works for even column sizes, so only .col-X-2, .col-X-4, col-X-6, col-X-8, and col-X-10 are supported.

Approach 2 (the old margin:auto)

You can center any column size by using the proven margin: 0 auto; technique. You just need to take care of the floating that is added by Bootstrap's grid system. I recommend defining a custom CSS class like the following:

.col-centered{
    float: none;
    margin: 0 auto;
}

Now you can add it to any column size at any screen size, and it will work seamlessly with Bootstrap's responsive layout:

<div class="row">
    <div class="col-lg-1 col-centered"></div>
</div>

Note: With both techniques you could skip the .row element and have the column centered inside a .container, but you would notice a minimal difference in the actual column size because of the padding in the container class.

Update:

Since v3.0.1 Bootstrap has a built-in class named center-block that uses margin: 0 auto, but is missing float:none, you can add that to your CSS to make it work with the grid system.

This is not my code, but it works perfectly (tested on Bootstrap 3) and I don't have to mess around with col-offset.

Demo:

/* centered columns styles */

.col-centered {
  display: inline-block;
  float: none;
  /* inline-block space fix */
  margin-right: -4px;
  background-color: #ccc;
  border: 1px solid #ddd;
}
<div class="container">
  <div class="row text-center">
    <div class="col-xs-6 col-centered">Column 6</div>
    <div class="col-xs-6 col-centered">Column 6</div>
    <div class="col-xs-3 col-centered">Column 3</div>
    <div class="col-xs-3 col-centered">Column 3</div>
    <div class="col-xs-3 col-centered">Column 3</div>
  </div>
</div>

We can achieve this by using the table layout mechanism:

The mechanism is:

  1. Wrap all columns in one div.
  2. Make that div as a table with a fixed layout.
  3. Make each column as a table cell.
  4. Use vertical-align property to control content position.

The sample demo is here

To be more precise Bootstrap's grid system contains 12 columns and to center any content let’s say, for instance, the content takes up one column. One will need to occupy two columns of Bootstrap's grid and place the content on half of the two occupied columns.

<div class="row">
   <div class="col-xs-2 col-xs-offset-5 centered">
      ... your content / data will come here ...
   </div>
</div>

'col-xs-offset-5' is telling the grid system where to start placing the content.

'col-xs-2' is telling the grid system how many of the left over columns should the content occupy.

'centered' will be a defined class that will center the content.

Here is how this example looks like in Bootstrap's grid system.

Columns:

1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 | 11 | 12

.......offset....... .data. .......not used........

To center more than one column in a Bootstrap row - and the number of cols are odd, simply add this css class to all the columns in that row:

.many-cols-centered {  // To horizontally center bootstrap odd cols, eg col-lg-9, col-md-3, works well in lg
  display:inline-block;
  float:none;
}

So in your HTML you have something like:

<div class="row text-center"> <!-- text-center centers all text in that row -->
    <div class="col-lg-3 col-md-3 col-sm-3 col-xs-12 many-cols-centered">
        <img src='assets/image1.jpg'>
        <h3>You See</h3>
        <p>I love coding.</p>
    </div>
    <div class="col-lg-3 col-md-3 col-sm-3 col-xs-12 many-cols-centered">
        <img src='assets/image2.jpg'>
        <h3>You See</h3>
        <p>I love coding.</p>
    </div>
    <div class="col-lg-3 col-md-3 col-sm-3 col-xs-12 many-cols-centered">
        <img src='assets/image3.jpg'>
        <h3>You See</h3>
        <p>I love coding.</p>
    </div>
</div>

Bootstrap version 3 has a .text-center class.

Just add this class:

text-center

It will simply load this style:

.text-center {
    text-align: center;
}

Example:

<div class="container-fluid">
  <div class="row text-center">
     <div class="col-md-12">
          Bootstrap 4 is coming....
      </div>

        <div class="col-md-6 brd">
            <div class="center-block">1 center-block</div>
        </div>
        <div class="col-md-6 brd">
            <div class="center-block">2 center-block</div>
        </div>
    </div>
</div>
<div class="row">
    <div class="col-xs-2 col-center-block">row col-xs-2 col-center-block</div>
</div>

Helper classes center

Row column center using col-center-block helper class.

As koala_dev used in his approach 1, I would prefer the offset method instead of center-block or margins which has limited usage, but as he mentioned:

Now, there's an obvious drawback for this method, it only works for even column sizes, so only .col-X-2, .col-X-4, col-X-6, col-X-8 and col-X-10 are supported.

This can be solved using the following approach for odd columns.

Just set your one column that displays content to col-xs-12 (mobile-first ;-) and configure the container only to control how wide you want your centred content to be, so:

.container {
  background-color: blue;
}
.centered {
    background-color: red;
}
<body class="container col-xs-offset-3 col-xs-6">
    <div class="col-xs-12 centered">
        <img data-src="holder.js/100x100" alt="" />
    </div>
</body>

<body class="container col-xs-offset-1 col-xs-10">
    <div class="col-xs-12 centered">
        <img data-src="holder.js/100x100" alt="" />
    </div>
</body>

Don't forget to add !important. Then you can be sure that element really will be in the center:

.col-centered{
  float: none !important;
  margin: 0 auto !important;
}

This is probably not the best answer, but there is one more creative solution to this. As pointed out by koala_dev the column offsetting works only for even column sizes. However, by nesting rows you can achieve centering uneven columns as well.

To stick with the original question where you want to center a column of 1 inside a grid of 12.

  1. Center a column of 2 by offsetting it 5
  2. Make a nested row, so you get a new 12 columns inside your 2 columns.
  3. Since you want to center a column of 1, and 1 is "half" of 2 (what we centered in step 1), you now need to center a column of 6 in your nested row, which is easily done by offsetting it 3.

For example:

<div class="container">
  <div class="row">
    <div class="col-md-offset-5 col-md-2">
      <div class="row">
        <div class="col-md-offset-3 col-md-6">
          centered column with that has an "original width" of 1 col
        </div>
      </div>
    </div>
  </div>
</div>

See this fiddle, please note that you have to increase the size of the output window in order too see the result, otherwise the columns will wrap.
