Introduction
00:00:00HTML Structure: Doctype, Head, Body, and Tag Types Begin with , then wrap the page in the html element divided into head and body. Pair tags have both opening and closing forms that contain content, while self-closing tags like meta carry information without inner text. Attributes are key–value pairs that describe elements, such as lang='en'. The body holds what users see; the head carries document data.
Link CSS and JavaScript to Add Style and Behavior Add styling with a link element to CSS and behavior with a script element that references an external JavaScript file. Removing these links immediately removes their effects, revealing that CSS and JS are optional enhancements layered onto HTML. Scripts can be included in the head or near the end of the document; they run when loaded. When editing CSS, live preview may not refresh automatically, so a manual reload can be necessary.
Titles and Meta Descriptions Power SEO and Context Use the title element to label the page; browsers display it, and search engines parse it for ranking and context. Updating titles per page is a strong practice because it describes the specific content users can expect. Meta tags in the head—especially meta name='description'—convey what the document is about and often appear in search results. The head collects this metadata alongside links and script references, while the body remains dedicated to visible content.
Work Smarter and Preview Your Site on a Phone Accelerate development by copying stable, reusable HTML snippets and focusing original effort where copying cannot help; senior skill lies in knowing where to copy from and how to paste. To preview on a phone, find your IPv4 address with ipconfig, set VS Code Live Preview to use that local IP, and ensure your Wi‑Fi network is marked Private. Restart VS Code, open the preview, and load http://your-ip:port (e.g., 192.168.1.199:5000 or 3000) on the phone. This mirrors your in-progress site on mobile so you can validate the experience where most visitors browse.
