A "web font" is a special font that is optimised for use on websites. In the field of web design, web fonts are used to display text on a website in certain fonts that are not necessarily installed on the user's device.

In contrast to the standard fonts that are pre-installed on most operating systems, web fonts can be individually selected and integrated into a website. This allows the web designer to ensure a consistent visual design and use the desired font style, regardless of whether users have the font installed on their devices or not.

An example of the use of web fonts would be if you want to use a special handwriting font on your website. You can then select a suitable web font and integrate it into the website code. When visitors call up the page, the text is displayed with the desired font, even if they do not have the font installed on their device.

Web fonts are usually integrated into the website code via CSS (Cascading Style Sheets). There are various ways to integrate web fonts, including the use of services or libraries from font providers.

Overall, web fonts allow greater creative freedom and flexibility when choosing fonts in web design projects. They help to ensure that the texts on a website are displayed attractively and uniformly, regardless of the fonts installed on the user's device.
