2.5.6 Concurrent Input Mechanisms
It must be possible to switch between input types (mouse, keyboard, touch, voice) without losing access to any functionality.
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.
3.1.1 Language of Page
Each page must have a <html lang=""> attribute that matches the main language of the page.
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.
3.1.3 Unusual Words
Unusual terms, jargon, or figurative language should be avoided when possible, or explained the first time they appear.
3.1.4 Abbreviations
Abbreviations and acronyms should be avoided when possible, or explained the first time they appear.
3.1.5 Reading Level
If content requires reading skills above lower secondary education (around 9th grade), provide a simpler version, a summary, a visual aid, or a spoken version to help with understanding.
3.1.6 Pronunciation
If a word can be pronounced in different ways with different meanings, the intended meaning must be clarified to avoid confusion or ambiguity.
3.2.1 On Focus
No unexpected changes must happen when an element receives focus (like open a popup, move focus, submit a form).
