Css Problem Overview

Is there any way to center html elements vertically or horizontally inside the main parents?

Css Solutions

Solution 1 - Css

Update: while this answer was likely correct back in early 2013, it should not be used anymore. The proper solution uses offsets, like so:

class="mx-auto"

As for other users suggestion there are also native bootstrap classes available like:

class="text-center"
class="pagination-centered"

Solution 2 - Css

From the Bootstrap documentation:

> Set an element to display: block and center via margin. Available as a mixin and class.

<div class="center-block">...</div>

Solution 3 - Css

If you are trying to center an image in a div, but the image won't center, this could describe your problem:

JSFiddle Demo of the problem

<div class="col-sm-4 text-center">
    <img class="img-responsive text-center" src="myPic.jpg" />
</div>

The img-responsive class adds a display:block instruction to the image tag, which stops text-align:center (text-center class) from working.

SOLUTION:

<div class="col-sm-4">
    <img class="img-responsive center-block" src="myPic.jpg" />
</div>

JSFiddle demo of solution

Adding the center-block class overrides the display:block instruction put in by using the img-responsive class. Without the img-responsive class, the image would center just by adding text-center class

Also, you should know the basics of flexbox and how to use it, since Bootstrap 4 now uses it natively.

Solution 4 - Css

In Bootstrap 4, the centering methods have changed.

Horizontal Center in Bootstrap 4

text-center is still used for display:inline elements
mx-auto replaces center-block to center display:flex children
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.

Solution 5 - Css

You may directly write into your CSS file like this:

.content {
  position: absolute;
  top: 50%;
  left:50%;
  transform: translate(-50%,-50%);
  }

<div class = "content" >
  
   <p> some text </p>
  </div>

<style>
    html, body {
        height: 100%;
        margin: 0;
        padding: 0 0;
    }

        margin: 0 auto;
    }

<body>
    <div class="container-fluid">
        <div class="row-fluid">
            <div class="offset3 span6 centering">
                content here
            </div>
        </div>
    </div>
</body>

}

 <div class="span8 centering"></div>

Solution 8 - Css

With Bootstrap 4 you can use flex-based HTML classes d-flex, justify-content-center, and align-items-center:

<link href="https://cdn.jsdelivr.net/npm/[email protected]/dist/css/bootstrap.min.css" rel="stylesheet"/>
<div class="d-flex justify-content-center align-items-center">
    <button type="submit" class="btn btn-primary">Create</button>
</div>

Source: Bootstrap 4.1

Solution 9 - Css

I like this solution from a similar question:

> Use bootstrap's text-center class on the actual table data <td> and table header <th> elements. So > > <td class="text-center">Cell data</td> and <th class="text-center">Header cell data</th>

Solution 10 - Css

Bootstrap 4's use of flex properties solve this. You can use these classes:

<link href="https://cdn.jsdelivr.net/npm/[email protected]/dist/css/bootstrap.min.css" rel="stylesheet"/>
<div class="d-flex justify-content-center align-items-center">
    <button type="submit" class="btn btn-primary">Create</button>
</div>

These classes will center your content horizontally and vertically.

Solution 11 - Css

I discovered in Bootstrap 4 you can do this:

center horizontal is indeed text-center class

center vertical however using bootstrap classes is adding both mb-auto mt-auto so that margin-top and margin bottom are set to auto.

Solution 12 - Css

for bootstrap4 vertical center of few items

d-flex for flex rules

flex-column for vertical direction on items

align-items-center for horizontal centering

justify-content-center for vertical centering

style='height: 300px;' must have for set points where center be calc or use h-100 class

    <link href="https://cdn.jsdelivr.net/npm/bootstrap@4.6.0/dist/css/bootstrap.min.css" rel="stylesheet"/>
<div class="d-flex flex-column align-items-center justify-content-center bg-secondary" style="
    height: 300px;
">
    <div class="p-2 bg-primary">Flex item</div>
    <div class="p-2 bg-primary">Flex item</div>
    <div class="p-2 bg-primary">Flex item</div>
</div>
