How the web works: browser, server, HTML

The web is a conversation between two programs: the browser asks, the server answers. The request travels over HTTP/HTTPS — kapnula.de becomes an IP via DNS (the internet’s phone book). The server sends HTML — the skeleton, CSS — the clothing, JavaScript — the behaviour. DevTools (F12) are the X-ray: inspect any page, change colours live.

●HTML is structure: <h1> heading, <p> paragraph, <a> link
●CSS is the look: colours, fonts, spacing
●JavaScript is the logic: buttons, forms, animation

🌐 F12 → the Network tab shows everything the page loads: images, scripts, even fonts. That is how all pros debug.
