# Accessibility
Using semantic HTML plays a key role when it comes to accessibility.
## Accessible Rich Internet Applications - ARIA
WAI-ARIA (the Accessible Rich Internet Applications specification) defines a way to make Web content and Web applications more accessible to people with disabilities.
> Note: It is [recommended](https://www.w3.org/TR/using-aria/#notes2) to use semantic elements as the primary method to achieve accessibility rather than adding aria attributes. Adding aria attributes should be seen as a secondary method for creating accessible elements.
### Role
The `role` attribute describes the role the element plays in the context of the document.
Review the list of [WAI-ARIA roles](https://www.w3.org/TR/wai-aria-1.1/#landmark_roles).
## Icons
When using icons or images that aren't absolutely needed to understand the context, we should use `aria-hidden="true"`.
On the other hand, if an icon is crucial to understand the context we should do one of the following:
1. Use `aria-label` in the element with a meaningful description
1. Use `aria-labelledby` to point to an element that contains the explanation for that icon
## Form inputs
In forms we should use the `for` attribute in the label statement:
```html
<div>
<label for="name">Fill in your name:</label>
<input type="text" id="name" name="name">
</div>
```
## Testing
1. On MacOS you can use [VoiceOver](https://www.apple.com/accessibility/mac/vision/) by pressing `cmd+F5`.
1. On Windows you can use [Narrator](https://www.microsoft.com/en-us/accessibility/windows) by pressing Windows logo key + Control + Enter.
