1. HTML5 Document Structure Tags
These tags form the fundamental blueprint of any HTML5 document, providing essential metadata and structuring the entire page.
<!DOCTYPE html>
: Defines the document type and version (HTML5). It's crucial for correct rendering.<html>
: The root element, encapsulating all other elements on the page. It often includes thelang
attribute (e.g.,<html lang="en">
) for accessibility.<head>
: Contains meta-information that isn't directly visible on the page but is vital for browsers and search engines.<title>
: Sets the title displayed in the browser tab or window. Highly important for SEO.<meta>
: Provides various metadata, likecharset="UTF-8"
for character encoding, orname="viewport"
for responsive design.<link>
: Links to external resources, typically CSS stylesheets (e.g.,<link rel="stylesheet" href="styles.css">
).<style>
: Used for embedding CSS directly within the HTML document.<script>
: Embeds or links to JavaScript files for dynamic functionality.<body>
: Contains all the visible content of your web page.
2. Semantic Structural Tags (New in HTML5)
HTML5 introduced semantic tags to give meaning to content beyond just presentation. This improves accessibility, SEO, and makes your code more readable.

: Content related to the main content but separate (e.g., sidebar, pull quote).<header>
: Introductory content for a section or document, often containing headings, logos, or navigation.<footer>
: Concluding content for a section or document, typically containing copyright, contact info, or related links.<main>
: The dominant content of the<body>

and<figcaption>
: Used for self-contained content (like images, diagrams, code examples) with an optional caption.<mark>
: Highlights or marks text for reference.<time>
: Represents a specific time or date.
