Use semantic HTML, give interactive elements accessible names (aria-label for icon buttons, alt for images), ensure keyboard accessibility, manage focus for modals and menus, ensure sufficient color contrast, use ARIA carefully, and test with a screen reader.
Because it gives screen readers the structure for free, without any extra attributes. A button is a button, a nav is a nav, and a main is a main. Semantic HTML is the foundation of accessibility, before ARIA.
Give them an aria-label. An icon-only button has no visible text, so screen readers have nothing to announce. An aria-label provides the accessible name that describes the button's action.
