Accessibility in HTML

Accessibility (a11y) ensures that your website is usable by everyone — including users with visual, motor, or other impairments.

Why Accessibility Matters

Not every user interacts with the web in the same way. Some use screen readers, keyboards, or alternative input devices. An accessible website offers a better experience for all users.

Alt Attribute for Images

Always provide an alt attribute for <img> elements. It describes the image content, helping screen reader users understand what the image represents.

Form Fields and Labels

Always pair form fields with <label> elements linked by 'for' and 'id'. This allows screen readers to correctly associate the input with its label.

Keyboard Navigation Support

Not all users use a mouse. The <tabindex> attribute helps make elements keyboard-accessible via the Tab key.

Using ARIA Attributes

ARIA (Accessible Rich Internet Applications) attributes help describe complex UI components that are not natively supported by HTML. For example, <aria-label> can be used for buttons.

Helpful Tips

Following a few basic rules can significantly improve your website's accessibility. These practices benefit not only users with disabilities but everyone using your site.

• <alt> – Text description for images
• <label> – Connect form inputs with their labels
• tabindex – Make an element focusable via keyboard
• aria-label – Provide extra context for screen readers
• contrast – Ensure good contrast between text and background
