What does a style sheet contain?

A style sheet is primarily used in web development to define how HTML elements are displayed on a web page. It contains formatting information, such as styles for fonts, colors, margins, spacing, and layout, allowing for a consistent look and feel across multiple pages within a website.

By separating content from presentation, style sheets enable developers to easily manage the visual aspects of a site without altering the HTML structure. This separation improves maintainability and allows for more efficient design updates. The most common type of style sheet is CSS (Cascading Style Sheets), which provides great flexibility for creating responsive and visually appealing web pages.
