Bootstrap 4 - Center List

Question

I am building an app with the Bootstrap 4 beta. This app is really basic at the moment and has a single inline list. I'm trying to center this list horizontally in the middle of the screen. As shown in this Bootply, I thought justify-content-center would do it. However, that did not work. I tried the other centering classes I saw listed here without any luck. My list looks like this:

<div>
  <ul class="list-inline justify-content-center">
    <li class="list-inline-item">Item 1</li>
    <li class="list-inline-item">Item 2</li>
    <li class="list-inline-item">Item 3</li>
    <li class="list-inline-item">Item 4</li>
    <li class="list-inline-item">Item 5</li>    
  </ul>
</div>

How can I center an inline list with the Bootstrap 4 beta?

Answer 1

Use text-center OR,

Use mx-auto inside a flexbox container (d-flex)..

https://www.bootply.com/6COUMfNrEU

<div class="d-flex">
  <ul class="list-inline mx-auto justify-content-center">
    <li class="list-inline-item">Item 1</li>
    <li class="list-inline-item">Item 2</li>
    <li class="list-inline-item">Item 3</li>
    <li class="list-inline-item">Item 4</li>
    <li class="list-inline-item">Item 5</li>    
  </ul>
</div>

How to centering works in Bootstrap 4...

text-center is used for display:inline elements

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 centering methods...

Center text or inline elements: text-center

<div class="container">
    <h1 class="text-center">i'm centered</h1>
    <div class="row">
        <div class="col text-center">i'm centered!</div>
    </div>
</div>

Center display:block or display:flex: mx-auto

<div class="row">
    <div class="col-12">
        <img class="mx-auto d-block" src="//placehold.it/200x150?text=mx-auto">
    </div>
</div>

Columns can also be centered with: mx-auto, because row is display:flex

<div class="row">
    <div class="col-4 mx-auto">
        <h6>I'm .col-4 centered</h6>
    </div>
</div>

If you want to use bootstrap classes then you can use row

<link href="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0-alpha.6/css/bootstrap.min.css" rel="stylesheet"/>

<div class="container">
  <ul class="list-inline d-flex justify-content-center">
    <li class="list-inline-item">Item 1</li>
    <li class="list-inline-item">Item 2</li>
    <li class="list-inline-item">Item 3</li>
    <li class="list-inline-item">Item 4</li>
    <li class="list-inline-item">Item 5</li>    
  </ul>
</div>

Otherwise, Simply text-align:center is enough.

ul.list-inline {
  text-align: center
}

<link href="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0-alpha.6/css/bootstrap.min.css" rel="stylesheet" />

<div>
  <ul class="list-inline">
    <li class="list-inline-item">Item 1</li>
    <li class="list-inline-item">Item 2</li>
    <li class="list-inline-item">Item 3</li>
    <li class="list-inline-item">Item 4</li>
    <li class="list-inline-item">Item 5</li>
  </ul>
</div>
