How a web page is built
HTML, CSS and JavaScript each have their own job.
HTML is the structure — headings, paragraphs, pictures and links. Think of it as the skeleton.
CSS is the style — colours, fonts and layout. JavaScript adds behaviour, like buttons that do things.
When you visit a site, your browser downloads these files and puts them together into the page you see.
Key idea
HTML = structure, CSS = style, JavaScript = behaviour.
Try it
Open any website and spot one heading, one picture and one button.
