- Title Tag: Sets the title of the web page displayed in the browser tab.
- Meta Tags: Provide information about the page, such as the character set, author, and description.
- Link Tags: Connect external resources like CSS files.
- Script Tags: Include or reference JavaScript files.
2. Body Section
The body section contains the visible content of the web page.

3. Cascading Style Sheets (CSS)
