This guide follows a long-form HTML course recorded in 2020. It introduces document structure and practical markup concepts; it is not a complete or current course in JavaScript, CSS, or modern web application development. HTML is maintained as a living standard, so consult current documentation when building a site.

Start with a document structure

An HTML document typically declares its doctype, language, character encoding, viewport, page title, and body. Semantic elements such as <header>, <nav>, <main>, <section>, and <footer> communicate the role of page regions. Use heading levels in a logical hierarchy and choose elements for their meaning, not only their appearance.

Make layouts and content usable

CSS controls presentation, while HTML provides structure and JavaScript can add behavior. A viewport declaration and responsive CSS help a page adapt to different screens. Media queries can adjust layout when the available width or other display conditions change.

Give meaningful images concise alternative text; decorative images can use empty alt text. Write descriptive link labels so readers can tell where a link goes. Associate visible form labels with their controls. Browser checks such as required or an email input improve usability but are not a security boundary: validate and safely handle untrusted input on the server as well.

Course chapters

The original course includes chapters on introductory HTML, document structure, text and semantic elements, links and media, forms, responsive behavior, and practice. Timestamped links below open the corresponding point in the original video. The course predates current browser and standards changes, so verify syntax and compatibility against current references before applying it.
