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.

Properly Opening, Closing, and Nesting HTML Tags

No source links recorded for this answer.

"Tags should be properly opened and closed and nested" means three simple rules that keep your HTML valid and predictable: 1. Every element that requires a closing tag must have one. - Opening tag: <tag> — Closing tag: </tag> - Example: <p>This is a paragraph.</p> - Exceptions (void elements) are self-contained and don’t get a separate closing tag: <img src="...">, <br>, <hr>, <input>, etc. 2. Tags must be nested in a well-formed, LIFO (last-in, first-out) order. - If you open A, then B, you must close B before closing A. - Correct: <p><strong>bold text</strong></p> - Incorrect: <p><strong>bold text</p></strong> — this breaks structure and can render unpredictably. 3. Closing tags match the opening tags exactly. - Case-insensitive in HTML (so </P> works), but use consistent lowercase for clarity: </p>, </div>, </a>. - Don’t try to close a different element than the one opened. Why it matters: - Browsers parse HTML into a DOM tree. Proper nesting produces the intended tree and predictable styles/behavior. - Bad nesting can cause layout issues, broken links, incorrect text formatting, and accessibility problems (screen readers rely on structure). - Valid HTML is easier to debug, maintain, and style with CSS. Quick examples: - Good: <ul> <li><a href="#">Item</a></li> <li><a href="#">Item 2</a></li> </ul> - Bad: <ul> <li><a href="#">Item</li></a> <!-- anchors closed after list item — wrong --> </ul> Further reading: - MDN: "Tags and normalized markup" and HTML syntax: https://developer.mozilla.org/en-US/docs/Web/HTML/Element - W3C / HTML specification for formal rules: https://www.w3.org/TR/html52/markup.html Tip: When editing, use an editor with tag highlighting or an HTML linter to catch nesting errors quickly.
