The role of typography in website design is to make the website's content easy to read and visually appealing. The right font can help to establish the tone and personality of a website, and can also improve its overall aesthetic.
When choosing a font for a website, it's important to consider the readability of the font, as well as its compatibility with the website's design and the brand's identity. For example, a serif font may be more appropriate for a traditional, professional brand, while a sans-serif font might be better suited to a modern, tech-focused brand.
It's also important to avoid using too many different fonts on a single website, as this can make the design appear cluttered and difficult to read.
