Overview

CSS (Cascading Style Sheets) is the language used to style and layout web pages, controlling how HTML elements look and appear on screen. You'll learn how to change colors, fonts, spacing, and positioning to create visually appealing websites. CSS works alongside HTML to separate the structure of a page from its visual presentation.

Key Points

• CSS uses selectors to target HTML elements and apply styling rules to them
• Properties like color, font-size, margin, and padding control the appearance and spacing of elements
• The box model describes how content, padding, borders, and margins work together around elements
• CSS can be written inline, in style tags, or in external stylesheets for better organization
• Responsive design techniques like media queries allow websites to adapt to different screen sizes

Why This Matters

CSS is essential for creating modern, professional websites that look good on all devices and provide a better user experience. Understanding CSS is a fundamental skill for web development and is used by virtually every website on the internet.
