What Is CSS and Why Is It Essential for Web Design?

CSS (Cascading Style Sheets) is a stylesheet language used to describe the presentation of a document written in HTML or XML. It is essential for web design because it controls the layout, colors, fonts, and overall appearance of a web page. CSS allows developers to separate content from presentation, making it easier to maintain and update the design of a website.

How Does CSS Work with HTML and JavaScript?

CSS works closely with HTML and JavaScript to create visually appealing and interactive web pages. While HTML provides the structure and content, CSS defines the styles and layout, and JavaScript adds interactivity. CSS can be linked to an HTML document using external stylesheets, embedded within the HTML, or applied inline. This separation of concerns allows for greater flexibility and maintainability in web development.

What Are the Key Features of CSS?

CSS offers several key features that make it a powerful tool for web design. It supports selectors and properties that enable precise control over the presentation of elements. CSS allows for responsive design, ensuring that web pages look good on different devices and screen sizes. It also supports animations and transitions, enabling dynamic visual effects. Additionally, CSS preprocessors like SASS and LESS provide advanced features like variables and nesting, enhancing the capabilities of CSS.
