How to Achieve Vertical Alignment in Bootstrap 4?

Vertical Alignment in Bootstrap 4

Aligning elements like text elements in Bootstrap 4 can be frustrating. Normally, the text-align utility can only be used for horizontal alignment, and most vertical alignment techniques are usually implemented by adding additional markup and overriding the default style.

flex-xs-middle class

Older versions of Bootstrap (such as Bootstrap 3 and earlier versions of Bootstrap 4) use the flex-xs-middle class to vertically center elements . This class can be added to a container to vertically center its content using flexbox:

<div class="container-fluid">
    <div class="row">
        <div class="col-xs-6">
            <div class="circle-medium backgrounds"></div>
        </div>
        <div class="col-xs-6 flex-xs-middle">
            <div class="name">Supplier</div>
        </div>
    </div>
    <div class="row">
        <div class="col-xs-6">
            <div class="circle-medium backgrounds"></div>
        </div>
        <div class="col-xs-6 flex-xs-middle">
            <div class="name">Supplier</div>
        </div>
    </div>
</div>

Bootstrap 4.0.0 Updates

As of Bootstrap 4.0.0, flexbox become the default setting. Therefore, it is now possible to align elements vertically by using several methods:

auto-margins

The my-auto utility can be used to automatically center elements vertically, for example:

<div class="row h-100">
    <div class="col-sm-12 my-auto">
        <div class="card card-block w-25">Card</div>
    </div>
</div>

flexbox

flexbox Utilities, such as align-self-center, can be used to align a single column or all columns in an entire row, for example:

<div class="row">
    <div class="col-6 align-self-center">
        <div class="card card-block">Center</div>
    </div>
    <div class="col-6">
        <div class="card card-inverse card-danger">Taller</div>
    </div>
</div>

Display Utilities

Bootstrap 4 also comes with a set of display utilities that can be used as an alternative to vertical alignment, for example:

<div class="row h-50">
    <div class="col-sm-12 h-100 d-table">
        <div class="card card-block d-table-cell align-middle">I am centered vertically</div>
    </div>
</div>

mPDF

mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
