Semantic HTML uses meaningful elements to describe the structure of a webpage.
These elements help browsers, screen readers, and search engines understand content better.
What Is Semantic HTML
Semantic elements clearly describe their purpose.
Instead of using only generic containers, semantic HTML explains what each section means.
Examples of Semantic Elements
Some common semantic elements include:
- header
- nav
- main
- section
- article
- footer
In this layout, screen readers cannot easily understand the role of each section.
Now screen readers can clearly identify each part of the page.
How Semantic HTML Helps Accessibility

- Makes page structure clear
- Reduces the need for extra ARIA roles
Semantic HTML and Keyboard Users

Semantic elements help them move through content efficiently.
Semantic HTML and SEO

This improves page ranking and discoverability.
Common Semantic HTML Mistakes
