What you will learn

SEO and Accessible Markup is part of the HTML track. You will learn the core idea, where it fits in a real project, and how to practice it safely.

Core concept

Start with the smallest useful version. Read the example, change one thing, then explain what changed. This habit turns tutorials into working skill.

Real project use

In production, this skill connects to planning, testing, accessibility, security, performance, and user experience. Good developers learn the syntax and the judgment around it.

Practice checklist

Build the example from scratch.
Change the names, values, and structure.
Break it on purpose, then fix it.
Save a short note about what you learned.
