Cascading style sheet (CSS)

Cascading Style Sheets (CSS) is a powerful stylesheet language used to control the visual presentation of web pages. It enables developers to separate the design and layout of a website from its content, streamlining the process of web design. By linking a CSS file to an HTML document, one can dictate the appearance of multiple elements—including fonts, colors, spacing, and positioning—across different pages from a single source. This not only reduces the amount of code required within HTML documents but also ensures a consistent look and feel throughout a website. Additionally, CSS has responsive design capabilities, allowing web pages to adapt seamlessly to various screen sizes and devices, enhancing user experience and accessibility.
