A **CSS Tutorial** helps beginners learn how to style web pages. CSS (Cascading Style Sheets) controls colors, fonts, layouts, and spacing, making HTML pages visually appealing. For example:

```html
Hello, CSS!
```

This code displays text in blue with a larger font size. CSS makes websites modern, responsive, and user-friendly.

Would you like me to make it **step-by-step tutorial style** instead of just a definition?
