The term CSS stands for Cascading Style Sheets. This is a fundamental technology used in web development for describing the presentation of a document written in HTML or XML. CSS controls the layout, fonts, colors, and overall visual appearance of web pages. The "cascading" aspect refers to the way styles can be applied in multiple layers, allowing for more specific styling rules to override more general ones, depending on where the styles are defined and their specificity.

Understanding this concept is crucial for web developers as it enables them to create visually appealing and consistent designs across different web pages. By using CSS, developers can separate content from design, making it easier to maintain and update web pages without altering the HTML structure. This separation enhances functionality, improves load times, and supports responsive design, allowing websites to adapt smoothly to different screen sizes and devices.
