Small utility classes that style an element right in its class list.

Extra information on an element: class, id, href, alt, and more.

The live page a script can search and change: find an element, then update it.

How styling works: color, size, and the box of space around every element.

Make a page respond: listen for a click or a key press, then run a function.

Reusable building blocks, like a navbar, a card, or a footer, composed into pages.

The elements that structure a web page: headings, paragraphs, sections, links.

Keep content in an array of objects and let a loop turn each one into markup.

Lay elements out in rows and columns at once, with items that can span several.

Line elements up in a row or column, and decide how the space between them is shared.

One page that fits a phone and a monitor: mobile first, then breakpoints.

Collect what a visitor types: labels, inputs, dropdowns, and a button that submits.

Ask another computer for data with fetch, wait for the answer, and put it on the page.
