HTML Accessibility
Accessibility means more people can use your page — with keyboards, screen readers, zoom, and different contexts. Good HTML is the foundation.
Direct answer
Prefer semantic elements (main, nav, button, headings). Label every form control. Write meaningful alt for informative images (empty alt for purely decorative ones). Keep heading levels orderly. Make sure interactive controls work with the keyboard, not only a mouse.
📊 Accessibility habits
| Habit | Why it helps |
|---|---|
| Semantic landmarks | Tools can jump to regions |
| Labels on controls | Names fields clearly |
| Alt on images | Describes non-text content |
| Logical headings | Outlines the page |
| Keyboard operable controls | Not everyone uses a pointer |

HTML Code
<nav aria-label="Main">
<a href="index.html">Home</a>
</nav>
<label for="q">Search</label>
<input id="q" name="q" type="search">
<img src="chart.png" alt="Bar chart: sales rose from 10 to 18">
<button type="submit">Search</button>Try it
- Audit a practice page for missing labels and alt text
- Ensure there is one
h1and nested headings do not skip wildly - Tab through links and buttons using only the keyboard
- Fix anything you cannot reach or understand without a mouse
Easy mistakes
- “Click here” links with no context
- Images that carry meaning but have empty or missing alt
- Custom clickable
divs that ignore keyboard users - Using ARIA to patch bad structure instead of fixing HTML first
Summary
- Semantics + labels + alt + headings matter
- Keyboard access is part of accessibility
- Start with good HTML before heavy ARIA
- Inclusive pages help everyone
