For students who can open a browser but have never built a page

· Beginner · 3 free
Learn how a web page travels from a server to your screen, then build one yourself with HTML, CSS and JavaScript. Ends with reading real data from an API using fetch.
Lessons
1
How a web page reaches your screen
What actually happens in the two seconds between typing a URL and seeing the page.
2
HTML structure and semantic tags
The skeleton of every page, and why the tag name you choose matters.
3
CSS: the box model, flexbox, and why layouts break
Every element is a box. Once you see the boxes, layout stops being guesswork.
4
JavaScript: variables, functions and the DOM
The language of the browser, and how it reaches into your page and edits it.
5
Events and forms
React to clicks and typing, and validate a form before it goes anywhere.
6
fetch and working with JSON from an API
Ask another server for data, wait for it properly, and show it on your page.
