level: AA
Level AA is the standard level most websites aim to meet. Most countries, states, and municipalities base their accessibility laws on WCAG AA. When people say “accessible website,” they typically mean WCAG AA compliance. Successfully implement every success criterion under Level AA and A to achieve this standard.
1.4.13 Content on Hover or Focus
When additional content appears on hover or keyboard focus (including long press on touch), it must stay visible until dismissed or no longer valid, be dismissible (e.g. using the key), and remain visible when hovered or focused.
2.4.5 Multiple Ways
At least two different ways must be available to find pages or content (e.g. navigation menus, on-page links, site search, or a sitemap).
2.4.6 Headings and Labels
Headings must describe what follows. Labels and buttons must clearly communicate what information is needed or what action will happen.
2.4.7 Focus Visible
A visible indicator must show which element is currently focused when navigating with a keyboard.
2.4.11 Focus Not Obscured (Minimum)
When an element receives focus, it must be at least partially visible.
2.5.7 Dragging Movements
Actions that require dragging (like reordering) must also be possible using buttons or another method that does not require dragging.
2.5.8 Target Size (Minimum)
Targets must be at least 24×24px, unless they are part of a sentence or block of text, surrounded by enough space, or near another target with the same function that meets the size.
3.1.2 Language of Parts
Any parts of the content in a different language must be marked with the correct lang attribute. Expressions borrowed from another language (like “déjà vu” in English) do not need this, unless pronunciation or understanding would be affected.

Navigation elements (like menus, links, search) must appear in the same place and order across pages.
3.2.4 Consistent Identification
Elements with the same function must look, behave, and be labeled the same way across pages.
