Introduction

CSS adds visual icons using third-party libraries like Font Awesome or Google Icons. These libraries provide vector shapes that developers insert into the HTML. You can then style these icons exactly like text fonts.

Syntax

1/* icon syntax */
2i.fas {
3  color: red;
4  font-size: 24px;
5}

Example

1<!-- this displays an icon -->
2<!DOCTYPE html>
3<html lang="en">
4  <head>
5    <link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/font-awesome/5.15.4/css/all.min.css">
6  </head>
7  <body>
8    <i class="fas fa-heart" style="color:red;"></i>
9  </body>
10</html>

Key Points

Icons load from external stylesheets.
Developers style icons using standard text properties.
The `font-size` property changes the icon size.
The `color` property changes the icon color.
