Web development final test — HTML and CSS for kids

Code tip

Read it like a browser — “work through every piece of code the way the browser would”

1. Find the topic: HTML, CSS, JavaScript or how the web works.
2. Read the code line by line, the way a browser would.
3. For sums and loops, write each step down and check it again.

Use it for: Final revision before moving on to a full programming course.

Worked example: ⚡ What number does this code print?
let books = 28;
books = books + 16;
books = books - 2;
console.log(books); → 42
