HTML and CSS lesson 2: The parts of every web page

UK version. UK school years and UK spelling. · US version of this lesson

Every page has the same skeleton: <!DOCTYPE html>, then <html> holding a <head> (facts about the page) and a <body> (what you see). A complete 40-minute HTML and CSS lesson for beginners (Year 7, KS3), from Unit 1: Web pages and HTML. You build real web pages right here in your browser – nothing to install.

Time: 40 minutes + 20 min homework
Year: Year 7, KS3 (ages 11–12)
You need: A computer or tablet, paper and a pencil
Marked: Instantly, with explanations

For parents: how to use this lesson

You don't need to know HTML yourself. The lesson explains each step on screen, the way Mr Babbage, our Head of Computing, likes it: a worked example first, then a go for your child. When your child builds a page, the browser draws it straight away and Classfern marks it with a checklist.

Read what your child will learn together.
Press Start the lesson below. Sit with your child for the teaching and the worked example (about 15 minutes): ask them to point at each tag and say what it does.
Let them do the practice on their own. If a page doesn't look right, the checklist says what is missing – let them find the mistake before you help.
Finish with the exit questions and the talk question: “What would a screen reader do with a page that doesn't say its language?”
Later that day or the next day: the homework (20 minutes), then a practice test.

Watch out for

The <title> is the big heading on the page. The title is on the tab; the heading on the page is <h1>.
The order of <head> and <body> doesn't matter. <head> always comes first, then <body>.

Miss Lovelace's tip for home: ask your child to change one thing on their page – a word, a colour, a size – and predict what will happen before they look. Predicting first is how programmers learn fastest.

What your child will learn

We are learning to write the skeleton of a web page from memory.

Success looks like

I can write the skeleton of a web page from memory.
I can say what goes in the <head> and what goes in the <body>.
I can give a page a title and a language.

Key words

DOCTYPE · head · body · title · lang attribute · nesting · comment

What to have ready

A device with a web browser (pages are built and checked right in the browser – nothing to install)
Paper for planning and sketching
A keyboard helps for typing code (a tablet works too)

The big ideas (for the adult)

Line one of every page is <!DOCTYPE html>. It tells the browser "this is a modern web page". Then everything goes inside <html lang="en"> – the lang tells screen readers and translation tools what language the page is in.

The <head> holds facts ABOUT the page that are not drawn on it, such as the <title> (the words on the browser tab, and in search results). The <body> holds everything you see.

Elements sit inside each other like boxes in boxes. A neat page indents or lines up its tags so you can see which box each one is in – and closes them in the reverse order to opening them. Comments, written , are notes for people reading the code; the browser ignores them.

Worked example: a whole page

<h1>My first page</h1>
<p>The tab says "My first page" too.</p>

The lesson

It runs here on the page. No sign-up and no names – nothing you type is sent anywhere. Each visit picks a new mix of questions.

Homework

20 minutes: predict what the browser will do, build or fix a short page, and check the key ideas – then a short reflection. New questions every time, all marked instantly.
