The language that makes websites look good -- colors, layouts, fonts.
CSS (Cascading Style Sheets) is the language that controls how HTML elements look. It handles colors, fonts, spacing, layout, animations, and responsive design. Without CSS, every website would look like a plain text document.
CSS is one of the three core Frontend technologies alongside HTML and JavaScript. Browsers process CSS during Rendering to style the DOM. Servers send CSS files to build web applications. Modern developers often use Tailwind CSS for utility-first styling and CSS containers for layout. CSS states like hover and focus create interactive visual feedback. JSX applies CSS classes in React components.
