CSS, or Cascading Style Sheets, is a stylesheet language used for describing the presentation of a document written in a markup language, such as HTML. CSS is used to control the appearance of the content on a web page, including font size, font family, colors, and spacing. It allows developers to separate the content of a web page from its presentation, making it easier to maintain and update the appearance of a website.
