Fonts and typefaces: the font-face rule as a basis in CSS

Typography is a key element in web design. Choosing the right fonts can make the difference between a boring website and a visually appealing one. In this article, we will explore the font-face rule, one of the fundamental tools in CSS to use custom fonts in our projects.

What is the font-face rule and how does it work?

The font-face rule is a CSS rule that allows us to use fonts that are not installed on the user's system and that are not standard web fonts. This rule gives us the flexibility to use custom fonts and ensure they display correctly in all browsers.

The basic syntax of the font-face rule is as follows:

@font-face { font-family: 'Font name'; src: url('source/path.ttf') format('format'); }

In the example above, we are declaring a new font with the name 'Font Name'. Next, we specify the source path using the src property and the corresponding file format.

Downloadable fonts and compatible formats

When using custom fonts, it is important to take into account the formats supported by different browsers. The most common formats are TrueType (.ttf), OpenType (.otf) and Web Open Font Format (.woff, .woff2).

To ensure that our fonts display correctly in different browsers, it is advisable to include multiple font formats in our font-face declaration. In this way, the browser will be able to select the format that best suits its capabilities.

Implementation of the font-face rule in CSS

To implement the font-face rule in our CSS, we must follow the following steps:

1. Download the font that we want to use in our project.
2. Place the font files in a folder accessible from our website.
3. Declare the font-face rule in our CSS file, specifying the name of the font and the path of the files in the different formats.
4. Use the font in our CSS by applying it to the desired elements using the font-family property.

It is important to remember that fonts must be available on the server and accessible to users visiting our website. Therefore, we must make sure to include the font files in our project or use services like Google Fonts to link the fonts from their server.

Example of implementing the font-face rule in CSS

@font-face { font-family: 'MyCustomFont'; src: url('fonts/myfont.woff2') format('woff2'), url('fonts/myfont.woff') format('woff'), T039;fonts/myfont.ttf' ) format('truetype'); } body { font-family: 'MyCustomFont', sans-serif; }

In the example above, we are declaring a new font with the name 'MyCustomFont' and specifying the paths of the font files in the WOFF2, WOFF and TrueType formats. Then, we apply this font to the body element using the font-family property.

Conclusion

The font-face rule is an essential CSS tool for using custom fonts in our web projects. Thanks to this rule, we can ensure that our fonts display correctly in all browsers and thus offer a visually appealing experience to our users.
