CSS (Cascading Style Sheets) is a fundamental language for styling web pages. It allows you to control the appearance and layout of your content, making it visually appealing and engaging. In responsive web design, CSS plays a crucial role in ensuring your website looks great and functions well on all devices.
Objectives
By the end of this tutorial, you will be able to:
- Understand the basic structure and syntax of CSS.
- Apply CSS styles to HTML elements to change their appearance.
- Create responsive layouts using CSS.
- Utilize CSS properties for typography, colors, and background styles.

Key Concepts
- Selectors: Used to target specific elements in your HTML document (e.g., p, .container, #header).
- Properties and Values: CSS properties control the appearance of elements, while values determine their specific characteristics (e.g., color: blue;).
- Rule Sets: A combination of a selector and a declaration block containing properties and values.
- Cascading: CSS rules are applied in a cascading order, with more specific rules taking precedence over less specific ones.
Getting Started
- Create an HTML file: Start with a basic HTML structure.
- Link a CSS file: Link a CSS file to your HTML document using the <link> tag.
- Start styling: Write CSS rules in your stylesheet to modify the appearance of elements.
