Web Content Accessibility Guidelines (WCAG) 2.0
All websites using the framework need to target a Level A compliance. Level AA should be reached whenever possible.
WAI-ARIA
Content is annotated using WAI-ARIA roles and states and properties. All widgets are WAI-ARIA compatible.
Access keys
All modern browsers support access keys to make keyboard-only navigation easier. To activate the access keys, they all need some modifier keys combination. Below is the list of theses combinations by browser and platform:
| Browser | Platform | Modifier keys |
|---|---|---|
| Chrome | Windows/Linux | Alt |
| Mac | Ctrl + Opt |
|
| Firefox | Windows/Linux | Alt + Shift |
| Mac | Ctrl + Opt |
|
| Internet Explorer | Windows | Alt |
| Safari | Mac | Ctrl + Opt |
| Windows | Alt |
|
| Opera | All | Shift + Esc |
The EPFL websites use an access key system derived from the UK Government Access Key Systems:
