HTML and CSS: The Building Blocks of the Web
HTML and CSS are the fundamental languages used to create and style websites.
HTML (HyperText Markup Language):
- The Structure: HTML provides the structure of a webpage, defining the content and its hierarchy.
2 - Elements and Tags: HTML uses elements, which are enclosed in tags, to represent different parts of a webpage, such as headings, paragraphs, images, links, and lists.
3 - Basic Structure:
HTML
<!DOCTYPE html> <html> <head> <title>My Website</title> </head> <body> <h1>Welcome to My Website</h1> <p>This is a paragraph.</p> </body> </html>
CSS (Cascading Style Sheets):
- The Style: CSS is used to style the HTML elements, controlling their appearance, layout, and formatting.
4 - Properties and Values: CSS properties (like color, font-size, and margin) are applied to HTML elements using selectors to define how they should be displayed.
5 - Example:
CSS
h1 { color: blue; font-size: 36px; text-align: center; } p { font-family: Arial, sans-serif; font-size: 16px; }
Why Use HTML and CSS?
- Flexibility: They offer a high degree of flexibility in creating diverse website designs.
6 - Simplicity: Both are relatively easy to learn and use.
- Cross-Platform Compatibility: HTML and CSS work across different browsers and devices.
7 - Open Standards: They are open standards, meaning they are freely available and widely supported.

In essence, HTML provides the content, and CSS defines the presentation of that content.
