What is CSS?
CSS stands for Cascading Style Sheets. It is a styling language used to control the presentation of web pages. With CSS, you can change:
- Fonts and text styles
- Backgrounds and colors
- Layouts and positioning
- Spacing (margins, padding)
- Animations and transitions
- Responsive design for all devices
Simply put, CSS separates design from structure, making websites clean, maintainable, and visually appealing.

CSS Basics You Must Know
Before diving into the complete reference, let’s revisit some basic CSS concepts.
1. CSS Syntax
Every CSS rule has the following structure:
selector {
property: value;
}
- Selector: The HTML element you want to style
- Property: The style attribute you want to change
- Value: The setting for that property
Example:
h1 {
color: blue;
font-size: 24px;
}
This makes all <h1> headings blue and sets their font size to 24px.
2. Ways to Add CSS
There are three main ways to use CSS in a web project:
- Inline CSS: Applied directly to an HTML element using the style attribute
- Internal CSS: Written inside a
<style> tag within the HTML <head>
- External CSS: Stored in a separate .css file and linked to the HTML
External CSS is the most preferred method as it keeps code organized.
3. Types of CSS Selectors
Selectors define which HTML elements are styled. Some common types:
- Universal Selector (*) → applies to all elements
- Element Selector (h1, p) → targets specific elements
- Class Selector (.className) → targets elements with a specific class
- ID Selector (#idName) → targets an element with a specific ID
- Group Selector (h1, h2, p) → applies to multiple elements
- Pseudo-classes (:hover, :first-child) → style elements in specific states
