♿ Accessible HTML Mini Lesson

Quick tips for building accessible, standards-based websites.

1. Color Contrast

Ensure text and UI elements have sufficient foreground–background contrast.

Do

Dark text (#00141A) on light background (#FDFDFD) — contrast ≥ 4.5:1

Don’t

Light-grey text on light-grey background — fails contrast.

2. Text Alternatives

Provide descriptive alt text for meaningful images and icons.

Do

Use alt="Golden Retriever in park" for meaningful images.

Don’t

Use blank or missing alt text on important images.

3. Keyboard Access

All interactive elements must be reachable and operable with a keyboard.

Do

Provide visible focus indicators and logical tab order.

Don’t

Rely on mouse-only drag actions without keyboard fallback.
