Web Fonts are specially designed typefaces that can be used on websites. Unlike standard fonts that are installed on a user's computer, web fonts are hosted on a server and loaded when a webpage is accessed. This allows designers to use a wider variety of fonts, enhancing the visual appeal of a site. To use web fonts, developers typically include a link to a font service, such as Google Fonts or Adobe Fonts, in their website's code. This ensures that the chosen fonts are displayed correctly across different devices and browsers, providing a consistent user experience.
