What is HTML?
HTML is a language for describing web pages.- HTML stands for Hyper Text Markup Language
- HTML is not a programming language, it is a markup language
- A markup language is a set of markup tags
- HTML uses markup tags to describe web pages
HTML Tags
HTML markup tags are usually called HTML tags- HTML tags are keywords surrounded by angle brackets like <html>
- HTML tags normally come in pairs like <b> and </b>
- The first tag in a pair is the start tag, the second tag is the end tag
- Start and end tags are also called opening tags and closing tags
HTML Documents = Web Pages
- HTML documents describe web pages
- HTML documents contain HTML tags and plain text
- HTML documents are also called web pages
The purpose of a web browser (like Internet Explorer or Firefox) is to read HTML documents and display them as web pages. The browser does not display the HTML tags, but uses the tags to interpret the content of the page:
Example 1.1 :
<!DOCTYPE html><html>
<head><title>Hello HTML</title></head><body><p>Hello World!</p></body></html>

Editing HTML
HTML can be written and edited using many different editors like Dreamweaver and Visual Studio.However, in this tutorial we use a plain text editor (like Notepad) to edit HTML. We believe using a plain text editor is the best way to learn HTML.Use Your Test Web For Learning
We suggest you experiment with everything you learn at W3Schools by editing your web files with a text editor (like Notepad).Note: If your test web contains HTML markup tags you have not learned, don't panic. You will learn all about it in the next chapters.
