Using Non-Standard Fonts in Web Development: How It's Done

When browsing the web, you might encounter pages that display fonts you don't have installed on your computer. Curious how this is possible? The answer lies within CSS and the introduction of the @font-face declaration.

How @font-face Works

@font-face allows web developers to import fonts from a font file into a webpage. This enables the use of non-standard fonts that may not be present on the user's device. When a browser encounters a @font-face declaration, it requests the specified font file from an external server. Once the file is downloaded, the font becomes available for use on the page.

Services for Hosting Font Files

To simplify this process, services like Typekit and Google's Font API emerged. These services host and serve font files, providing developers with an easy way to implement non-standard fonts while handling licensing and consistent rendering.

Alternative Techniques

In the past, alternative techniques such as Cufon and sIFR were used to embed fonts into web pages. However, these techniques are no longer widely utilized in favor of the @font-face declaration, which became a standard in later versions of CSS.

Considerations

While non-standard fonts can enhance the visual appeal of a website, it's important to note that they can impact performance and have licensing restrictions. It's crucial to choose fonts that support multiple browsers and versions, and to consider the potential legal implications of using licensed fonts.
