# ARIA — first rule of ARIA

> ARIA can make custom widgets accessible, but the first rule of ARIA is don't use ARIA. Reach for a native HTML element first; add ARIA only when nothing native fits.

## What it is

ARIA — Accessible Rich Internet Applications — is a set of HTML attributes (`role`, and the many `aria-*` attributes) that tell assistive technologies what a custom element is, what state it is in, and how it relates to other elements. ARIA never changes how something looks or behaves; it only affects the accessibility tree.

## Why it matters

ARIA is a sharp tool. Used well, it lets you describe widgets the HTML spec does not cover. Used badly, it overrides the real semantics of an element and makes the page *less* accessible than the unstyled HTML would have been. The W3C's own guide leads with five rules — and the first is the most important.

## How to implement

The five rules of ARIA, in plain English:

1. **Don't use ARIA if a native HTML element will do.** `<button>`, `<a href>`, `<input type="checkbox">`, `<details>` — these come with role, focus, and keyboard support for free.
2. **Don't change native semantics.** Never write `<h1 role="button">`. If you need a button, use a `<button>`.
3. **All interactive ARIA controls must be keyboard-operable.** A `role="button"` div without Space/Enter handlers is broken.
4. **Don't set `role="presentation"` or `aria-hidden="true"` on focusable elements.** You will hide controls from the very users who need them.
5. **Every interactive element needs an accessible name.** Use a visible label, `aria-label`, or `aria-labelledby`.

Common, useful ARIA attributes:

```html
<!-- An icon-only button needs a name -->
<button aria-label="Close">
  <svg aria-hidden="true" focusable="false">…</svg>
</button>

<!-- Associate a hint with an input -->
<label for="pw">Password</label>
<input id="pw" type="password" aria-describedby="pw-hint">
<p id="pw-hint">At least 12 characters.</p>

<!-- Group of toggle buttons sharing a label -->
<div role="group" aria-labelledby="format">
  <h3 id="format">Text format</h3>
  <button aria-pressed="true">Bold</button>
  <button aria-pressed="false">Italic</button>
</div>
```

- `aria-label` overrides the element's text — use only when there is no visible label.
- `aria-labelledby` points at the id of one or more existing elements; it takes precedence over `aria-label` and `<label>`.
- `aria-describedby` adds a description in addition to the name — for hints, errors, format examples.

## Common mistakes

- `role="button"` on a `<div>` with no `tabindex`, no key handlers, no focus style.
- Redundant roles: `<button role="button">`, `<nav role="navigation">`.
- `aria-label` written for SEO, in language different from the visible text — voice control users cannot say the visible text.
- `aria-hidden="true"` on a wrapper that contains a focusable button.
- ARIA states (`aria-expanded`, `aria-checked`) never updated by JavaScript when the UI changes.

## Verification

- Inspect every custom widget in the accessibility tree; the role, name, and state must match what is on screen.
- Run an automated checker for ARIA misuse.
- Test with a screen reader — the announcement must match how the control behaves.
