What is a font icon in html5

Font icons are fonts that use tiny images instead of letter forms. Like characters, each icon font is a vector element that scales as needed and can be modified using CSS styles.

The main reason to use icon fonts is that you can easily change the size, color, shape. Icon fonts are transparent in nature, so you can place them on any color or type of background, and you can also add strokes or change the opacity of the icons.

All setup operations can be done using CSS, so you don’t have to create a unique image for each new icon instance in your design (which is great for keeping your website design and code lightweight).

Icon fonts are vector images, which means they can be scaled without distortion. Like other fonts, you can make them larger or smaller as needed. Use icon fonts only as artistic elements, even in other text fields.
