A browser font, also known as a web font, is a font that can be rendered directly in a web browser. Unlike traditional fonts that are installed on a user's computer, browser fonts are hosted on a server and can be downloaded and displayed in a web page. They are commonly used by web designers to create visually appealing websites and to ensure consistent typography across different devices and browsers. There are many different browser fonts available, including free and paid options, and they can be customized in terms of size, color, and other attributes.
