Accessibility policy
Keyboard navigation (very important)
The entire application can be accessed using only the keyboard. The tab key traverses elements in a logical order. There are no keyboard traps (where you cannot exit a control). Focus is clearly visible (border, shadow, highlight, etc.). Dropdown menus, modals and popups work with the keyboard.
Color contrast
Text must have sufficient contrast against the background. Buttons, links and controls must be legible.
Images
Informative images have alternative text (alt).
Links and buttons
Links describe their destination. Avoid text like "Click here" or "More information".
Headings
The page must have a logical structure: h1 for the main title, h2 for sections, h3 for subsections.
Forms
All fields have an associated label. Required fields are identified. Errors are displayed clearly and messages indicate what needs to be corrected. Errors do not rely solely on the color red.
Page language
The lang attribute must exist on the html element.
Responsive
The audit usually checks mobile, tablet and desktop.
