HTML (HyperText Markup Language)The standard language used to create and design documents on the World Wide Web. It provides the basic structure, or 'skeleton', of a webpage.An entire `.html` file is an HTML document. For instance, `index.html`.
HTML ElementA complete component of a web page, which usually consists of a start tag, content, and an end tag.`<p>This is a paragraph.</p>` is a paragraph element.
HTML TagThe labels you use to mark up the beginning and end of an element. They are enclosed in angle brackets.`<h1>` is a start tag for a top-level heading. `</h1>` is its corresponding end tag.

Core Syntax & Patterns
The Basic Document Structure
`<!DOCTYPE html><html><head>...</head><body>...</body></html>`
Every HTML page must follow this structure. The `<!DOCTYPE html>` declares the document type. The `<html>` tag is the root element. The `<head>` contains meta-information (like the title), and the `<body>` contains the visible page content.
Tag Nesting
Tags must be closed in the reverse order they were opened. (Last-In, First-Out)
Think of tags as nested boxes. An inner box must be closed before the outer box. For example, `<p><strong>Correct</strong></p>` is valid, but `<p><strong>Incorrect</p></strong>` is not.
Element Syntax
`<tagname attribute="value"...

Challenging
A developer uses `<div class="header">` instead of the semantic `<header>` tag. Based on the tutorial's emphasis on semantic HTML, what is the primary disadvantage of this choice?
A.It harms accessibility and SEO because the tag `<div>` carries no intrinsic meaning about its content.
B.It will cause a syntax error because `class="header"` is not a valid attribute for a `<div>`.
C.It prevents the use of CSS to style the header, as styles can only be applied to semantic tags.
D.It is not supported by modern browsers and will not be displayed on the page.
Challenging
A student's webpage shows the correct content, but the browser tab displays the file name (e.g., 'index.html') instead of the intended title 'My Awesome Page'. Based on the tutorial's content, what is the most likely error in their code?
A.They wrote `<h1>My Awesome Page</h1>` in the `<body>` but forgot to add it to the `<head>`.
B.They forgot to include a `<footer>` element on the page.
C.They either omitted the `<title>` tag or placed it outside the `<head>` section.
D.The `<!DOCTYPE html>` declaration is missing from the top of the file.
Challenging
Given the 'Last-In, First-Out' rule for tag nesting, which of the following complex nested structures is valid?
A.<section><p>Here is an <em>important</section></em> point.</p>
B.<article><h1><a href="#">Title</a></h1><p>Content...</article></p>
C.<ul><li><p><strong>Item 1</p></strong></li></ul>
D.<main><section><h1>Title</h1><p>Some <strong>bold</strong> text.</p></section></main>
