CSS Icons: A Complete and Practical Guide

Icons play a very important role in the world of web design. They help make web pages look livelier and more attractive. By using CSS, you can create beautiful icons without the need for external images. The use of icons not only helps beautify pages but also improves usability and accessibility.

One of the common methods for creating icons is using icon fonts like Font Awesome or Material Icons. These fonts allow you to easily add icons to web pages that are easily customizable and scalable using CSS.

You can also use SVG elements or CSS Pseudo Elements such as ::before and ::after to create custom icons that can be quickly rendered and do not rely on external resources.

Another way to create icons is by using CSS Drawing techniques such as using border and box-shadow. This technique allows you to create simple and scalable icons with fewer resources.

Example of Creating an Icon with CSS

<style>
.icon {
  width: 50px;
  height: 50px;
  background-color: #333;
  display: inline-block;
  position: relative;
}
.icon::before {
  content: '';
  width: 20px;
  height: 20px;
  background-color: white;
  border-radius: 50%;
  position: absolute;
  top: 15px;
  left: 15px;
}
</style>

<div class="icon"></div>

Code Explanation

.icon: This class code defines the main block icon.
width and height: These determine the dimensions of the icon.
background-color: This specifies the background color of the icon.
display: This determines the display properties of the block.
position: This positions the icon relative to the parent container.
::before: This pseudo-element creates an inner element that resides within the icon.
