Set up roles and ARIA attributes

[illright]

Set up the necessary ARIA attributes and support keyboard navigation for the following components:

• [ ] Dialog (ARIA: Alert Dialog and ARIA: Modal Dialog)
• [ ] Button (ARIA: Button)
• [ ] Checkbox (ARIA: Checkbox (Two-state))
• [ ] Autocomplete (ARIA: Combobox with Listbox Popup and ARIA: Layout Grid)
• [ ] DatePicker (ARIA: Date Picker Dialog)
• [ ] RadioButton (ARIA: Radio Group)
• [ ] Tab (ARIA: Tabs with Manual Activation and ARIA: Tabs with Automatic Activation)

Think about how we can incorporate aria-labelledby in our components to allow effortless labelling.

Think about showing a keyboard arrows sign in the corner of the page to afford keyboard navigation.

Think about how to provide ARIA: Actions Menu Button for Dropdowns that form menus.

Implement focus traps and prevent scrolling for the modal.
