HTML Basics
In this chapter, we will introduce some basic HTML examples. Don’t worry if we use tags you have not learned about yet. We’ll explain everything as we go along.
HTML Documents
Every HTML document begins with a document type declaration: <!DOCTYPE html>
. This declaration is used to tell the web browser that the document is an HTML5 document. The HTML document itself begins with <html>
and ends with </html>
. The visible part of the HTML document is between <body>
and </body>
.

The <!DOCTYPE>
declaration represents the document type and helps browsers to display web pages correctly. It must only appear once, at the top of the page (before any HTML tags). The <!DOCTYPE>
declaration is not case sensitive. The <!DOCTYPE>
declaration for HTML5 is <!DOCTYPE html>
.
HTML Headings
HTML headings are defined with the <h1>
to <h6>
tags. <h1>
defines the most important heading, while <h6>
defines the least important heading. Here’s an example:

How to View HTML Source
Have you ever seen a web page and wondered “Hey! How did they do that?” Here’s how you can view the HTML source code:
- Right-click in an HTML page and select “View Page Source” (in Chrome) or “View Source” (in Edge), or similar in other browsers. This will open a window containing the HTML source code of the page.
- Inspect an HTML Element: Right-click on an element (or a blank area), and choose “Inspect” or “Inspect Element” to see what elements are made up of (you will see both the HTML and the CSS). You can also edit the HTML or CSS on-the-fly in the Elements or Styles panel that opens.
In the next lesson, we’ll delve deeper into HTML and explore more tags and attributes. Stay tuned!
