@font-face CSS At-Rule

Description

The CSS @font-face at-rule allows you to specify custom fonts to be used on a web page. This is useful because it gives you more control over the appearance of your text, and it allows you to use fonts that may not be installed on the user's computer.

To use the @font-face at-rule, you must first define a name for the font and then specify the location of the font file. The font file can be located on the same server as your web page, or it can be located on a different server.

Once you have defined the font, you can use it in your CSS like any other font. For example, you can use it to set the font family of a heading, paragraph, or other element.

Syntax

@font-face {
  [ font-family: <family-name>; ] ||
  [ src: <src>; ] ||
  [ unicode-range: <unicode-range>; ] ||
  [ font-variant: <font-variant>; ] ||
  [ font-feature-settings: <font-feature-settings>; ] ||
  [ font-variation-settings: <font-variation-settings>; ] ||
  [ font-stretch: <font-stretch>; ] ||
  [ font-weight: <font-weight>; ] ||
  [ font-style: <font-style>; ]
}
