CSS Syllabus

The CSS syllabus is a structured outline of topics that guide learners through the study of Cascading Style Sheets (CSS) — the language used to design and style web pages. Whether you’re a beginner or a web development student, understanding the CSS syllabus helps you systematically learn how to control layout, colors, fonts, responsiveness, and more.

This guide breaks down the core areas of a typical CSS syllabus in simple terms.
