Headings <h1>–<h6> give a page an outline; paragraphs <p> hold the text. <strong> marks important words and <br> is a line break. A complete 40-minute HTML and CSS lesson for beginners (Grades 6–7), 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
Grade: Grades 6–7 (ages 11–12)
You need: A computer or tablet, paper and a pencil
Graded: 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 grades 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: “How would you explain to a friend why a page should have only one `<h1>`?”
Later that day or the next day: the homework (20 minutes), then a practice test.

Watch out for

Use <h3> because it is the size I want. Pick the level for the outline; change the size with CSS.
<br> starts a new paragraph. It breaks a line inside the same paragraph.

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

What your child will learn

Learning goal: use one <h1> and then <h2> headings in order.

Success looks like

I can use one <h1> and then <h2> headings in order.
I can split text into paragraphs.
I can mark important words with <strong>.

Key words

heading · h1 to h6 · paragraph · line break · strong · outline

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)

Headings work like the headings in a book. There is one main heading, <h1>, then <h2> for each section and <h3> inside those. Browsers show <h1> at 32px – twice the normal 16px text – and each level after it smaller.

Choose a heading for its PLACE in the outline, not its size. People using screen readers often jump from heading to heading to find their way, so skipping from <h1> to <h3> is like a book with a missing chapter. (You can change sizes later with CSS.)

Each <p> is one paragraph; the browser adds space between paragraphs. <br> breaks a line inside a paragraph, for things like addresses. <strong> says "this is important" and browsers show it in bold. Remember to close </strong> – a forgotten closing tag makes the bold run on.

Worked example: an outline

<h1>Our school garden</h1>
<p>We grow <strong>vegetables</strong> and flowers.</p>
<h2>What we grow</h2>
<p>Beans, peas and sunflowers.</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 graded instantly.
