A browser asks, a server answers with text, and the browser draws it: the request and response every site runs on, plus the three languages that fill the page in.
How the Web Works
A browser asks, a server answers with text, and the browser draws it: the request and response every site runs on, plus the three languages that fill the page in.
HTML: The Structure
Elements, tags, attributes, and the document skeleton: writing the HTML a browser draws, one piece at a time.
CSS: The Style
The style layer, rule by rule: selectors, colors, the box model, and flexbox turn a plain HTML page into one that looks built on purpose.
Making It Interactive
HTML builds the page and CSS paints it, but JavaScript is what makes it move: the DOM, finding elements, and a button that actually does something.
Putting It Online
Three files on a laptop become a page anyone on earth can open: hosting, deploying, domains, and the padlock.
