2. Intro to HTML

Validating the code

It's important to validate our HTML code for 3 reasons:

• Maintainance: to write clean code that's easy for others to understand and maintain
• Search engines: adding the correct tags help our site get better rank in search engines
• Accessibility: valid HTML improves compatibility with accessible web browsers

Even if our code is not completly valid, most browsers will render it fine. The end user will not notice.

We can validate our code with this page from the World Wide Web Consortium (W3C). There's also a VS Code extension that I'm using that does the same thing.
