Web fonts are fonts that are downloaded by the browser on demand to render text in a specific typeface that is not pre-installed on the user's device. While crucial for branding and design, they must be loaded efficiently to avoid blocking text from being displayed or causing Cumulative Layout Shift (CLS) when the font is swapped in.
