Cascading Style Sheets (CSS) is a stylesheet language used to control the visual presentation of web pages written in HTML.
While HTML defines the structure and content of a webpage, CSS determines how that content looks — including its layout, colors, fonts, and spacing.
By separating content from design, CSS allows developers to maintain cleaner code, reuse styles across multiple pages, and create responsive layouts that adapt to different screen sizes. From simple color changes to complex animations, CSS plays a vital role in making modern websites visually appealing and user-friendly.
Here’s a list of 25 CSS-only projects, arranged from basic → advanced, designed to strengthen your understanding of layout, styling, animations, and responsiveness — all without using JavaScript.
