CSS is crucial for styling web pages, handling everything from text color to layout.

HTML provides the content, with a basic structure established in files like index.html.

The style attribute allows specific CSS properties to be applied to individual HTML elements.

IDs are unique identifiers for HTML elements, allowing specific styling without affecting others.

Classes enable the application of the same CSS rules to multiple elements, enhancing code efficiency.

Linking to external CSS files helps keep HTML clean and organized, separating structure from style.

Understanding the different selectors—tag, ID, and class—is fundamental for effective CSS styling.
