Quick recap — Module A5
12 lessons of a11y. The 4 things you cannot ship without:
- Landmark structure —
<main>+<nav>+<header>+<footer>. Screen-reader users navigate by landmark. - `aria-label` on icon-only buttons + nav — without text, the assistive tech has nothing to announce.
- Skip link —
<a href="#main">Skip to content</a>as the first focusable element. Keyboard users repeat-tab through nav otherwise. - Visible focus — never
outline: nonewithout a replacement. Use:focus-visibleto scope the ring to keyboard users.
If any feels random, redo A5-02 / A5-04 / A5-07 / A5-10 then come back.
