In CSS Icons of other libraries can be formatted using CSS styles. They can be customized according to size, color, shadow, etc. The icon is a graphical representation that conveys the specific meaning for which it is used & helps to navigate accordingly.
There are 3 types of icon libraries available, namely
- Font Awesome Icons
- Google Icons
- Bootstrap Icons
We will include the required CDN link from the available icon library, which will help us to use the pre-defined icon classes or we can customize it using the CSS.
Using Icons with CSS
In order to use icons, we need to add the required CDN link inside the <head> section. The following steps to add the predefined class in the HTML:
- Add the name of the icon class to any inline HTML element.
- The <i> and <span> elements are widely used to add icons.
- All the CSS icons are scalable vector icons that can be customized with the required CSS properties such as size, color, shadow, etc.
Note: All the above-mentioned libraries do not require any downloading or installation.
