Cascading Style Sheets (CSS)

CSS is a popular programming language used in web development to define the presentation and formatting of HTML documents. It allows designers to control the layout, colors, fonts, and other visual aspects of websites independently from the content of the pages. By separating design from content, CSS promotes consistency across a website's pages and enhances accessibility. Designers and developers can create visually appealing websites and make global changes by modifying a single CSS file, rather than editing each HTML page individually.
