Common Tags
Concept
Common Tags
Tags like p, h1 through h6, a, and img structure text, headings, links, and images on a page.
Headings should be used in order (one h1, then h2s under it, and so on) rather than picked for their default size — skipping levels confuses both screen readers and search engines.
- Explain the core idea behind Common Tags.
- Predict output before running a change.
- Test one realistic and one unusual input.
- Use the result to make the next decision.
- 1. Read one concept.
- 2. Change the example.
- 3. Run, compare, and explain.
- 4. Complete the challenge below.
Self-check before continuing
Without looking at the example, describe what changes when you modify one input in Common Tags. Then reopen the editor and prove your explanation with a small test.
You are ready to continue when you can predict, test, and explain the result.
Your turn
Write a small page with a heading, a paragraph, and a link to a website you like.
Ask about this lesson or your next move. The guide explains the path without taking the work away from you.
