Accessibility
Making the web usable for everyone — the WCAG standards and the human issues behind them.
5 principles
Colour Contrast & Legibility
Text needs enough contrast against its background to be read — WCAG's ratio is the floor, not the goal.
Read →WCAG POUR Principles
Web accessibility is organised around four principles: content must be Perceivable, Operable, Understandable, and Robust — failure on any one principle makes content inaccessible to some users.
Read →Keyboard Navigability
Every interactive element must be reachable and operable using a keyboard alone, with visible focus indicators showing where the user currently is.
Read →Alternative Text (Content Equivalence)
Every image, icon, or non-text element that conveys meaning must have a text alternative that communicates the same information to users who cannot see it.
Read →Focus Management
Keyboard focus must be visible at all times, move in a logical order, and be actively managed when content changes — especially when modals open, overlays appear, or dynamic content updates.
