CSS Icons

CSS does not have built-in icons, but it is possible to use CSS to create simple icons, and but there are several ways to add icons to a webpage using CSS.  Here are some techniques for creating icons using CSS:

 

Font Icons: 

Font icons use fonts to display icons instead of images. This technique uses a custom font that contains icons as its characters. By using CSS to change the font of an element, you can display an icon in that element. Some popular font icon libraries include Font Awesome, Material Icons, and Ionicons.

Example:

<head>
 <link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/font-awesome/5.15.3/css/all.min.css" />
</head>
<body>
 <i class="fas fa-heart"></i>
</body>

 

SVG Icons: 

SVG icons use vector graphics to create icons that can be scaled without losing quality. This technique uses an SVG file as the icon and embeds it directly into the HTML using the <svg> element. By using CSS to style the <svg> element, you can change the size, color, and other properties of the icon.

Example:


<body>
 <svg viewBox="0 0 24 24" width="24" height="24" fill="currentColor">
   <path d="M12 21.35L4.53 24l1.42-8.27L.12 9.24l8.5-.98L12 .65l3.88 7.61 8.5.98-5.83 5.49 1.42 8.27L12 21.35z"/>
 </svg>
</body>

 

CSS Icons: 

CSS icons use CSS to create simple shapes and designs that can be combined to form icons. This technique uses CSS properties like border-radius, transform, and box-shadow to create shapes like circles, squares, and triangles. By combining these shapes, you can create more complex icons.

Example:

<style>
 .circle {
   width: 50px;
   height: 50px;
   border-radius: 50%;
   background-color: red;
 }
</style>

<body>
 <div class="circle"></div>
</body>


By using these techniques, you can create a variety of icons using only CSS. However, for more complex or detailed icons, it may be necessary to use image files or external icon libraries.
