Foundations of your webpage

the browser which version of HTML the document.
- Syntax for this line: <!DOCTYPE html> , which specifies that the document is written in
HTML5

- HTML TAG: The ‘<html>’ tag is the container for all the other HTML elements on the page. It
is the second line in a HTML document. All other tags are placed inside the ‘<html>’ tag.

- Head Tag: The ‘<head>’ tag contains metadata about the HTML document, such as the title,
author, and description. The metadata is not displayed on the web page itself but is used by
search engines and other tools to understand the content of the page.
