Bare-Bones Basics of HTML

No source links recorded for this answer.

HTML (HyperText Markup Language) is the standard language for creating web pages. It uses tags to structure content. Key points: - Document structure - <!DOCTYPE html> — declares HTML5. - <html> — root element. - <head> — metadata: <title>, <meta>, <link>, <style>, <script> (usually not visible). - <body> — visible content: text, images, links, lists, etc. - Basic tags - <title>Your page title</title> — shown in browser tab (inside head). - Headings: <h1>…</h1> to <h6>…</h6>. - Paragraph: <p>Paragraph text</p>. - Links: <a href="https://example.com">link text</a>. - Images: <img src="image.jpg" alt="description"> (self-closing; include alt). - Lists: - Unordered: <ul><li>Item</li></ul> - Ordered: <ol><li>Item</li></ol> - Line break: <br> - Horizontal rule: <hr> - Attributes - Provide extra info inside opening tag: <tag attribute="value">. - Common attributes: id, class, href, src, alt, title, style. - Nesting and well-formedness - Tags should be properly opened and closed and nested (e.g., <p><strong>text</strong></p>). - Example minimal page <!DOCTYPE html> <html> <head> <meta charset="utf-8"> <title>My Page</title> </head> <body> <h1>Hello</h1> <p>This is a minimal HTML page.</p> <a href="https://example.com">Visit example</a> </body> </html> - Where to learn next - Mozilla Developer Network (MDN) HTML guide: https://developer.mozilla.org/en-US/docs/Web/HTML - W3C HTML specification and tutorials: https://www.w3.org/ and https://www.w3schools.com/html/ Tips: start by editing the example file, open it in a browser, and change tags/attributes to see effects.

What <!DOCTYPE html> Means

No source links recorded for this answer.

The declaration <!DOCTYPE html> at the top of an HTML file is a simple instruction to the web browser: it tells the browser to interpret the document as HTML5 and to render the page in “standards” or “no‑quirks” mode rather than in an old, backward‑compatibility mode. Key points, briefly: - Purpose: It signals the document type/version so browsers use the modern HTML parsing and CSS layout rules. Without it, some browsers fall back to “quirks mode,” emulating very old browser behavior and producing inconsistent layouts. - Not an HTML tag: It’s a declaration, not an element in the DOM; it isn’t nested and has no closing tag. - Simplicity: HTML5 standardized a single, short doctype — <!DOCTYPE html> — replacing the long, version‑specific strings used in older HTML/XHTML documents. - Backwards compatibility: Using this doctype avoids legacy quirks and ensures more predictable rendering across browsers. References: - MDN Web Docs — <!DOCTYPE>: https://developer.mozilla.org/en-US/docs/Glossary/Doctype - W3C — HTML5 specification (doctypes section): https://www.w3.org/TR/html5/syntax.html#the-doctype If you want, I can show how rendering differs with and without the doctype or how to test for quirks mode in your browser.
