BS4 Icons
Bootstrap 4 Icons
Bootstrap 4 lacks an icon library of its own (BS4 does not support the Glyphicons from Bootstrap 3). But there are lots of free icon libraries available, such Google Material Design Icons and Font Awesome.
Add the following to your HTML page to use Font Awesome icons (no download or installation needed):
<link data-minify="1" rel="stylesheet" href="https://codingask.com/wp-content/cache/min/1/releases/v5.7.0/css/all.css?ver=1730305204" crossorigin="anonymous">
Then, give any inline HTML element (such as <i> or <span>) the name of the icon class:
Example
<i class="fas fa-cloud"></i>
<i class="fas fa-coffee"></i>
<i class="fas fa-car"></i>
<i class="fas fa-file"></i>
<i class="fas fa-bars"></i>
