Accessibility helps people use the website through different devices and interaction methods. It should be considered during design and implementation.
Make controls understandable
Use meaningful link text and visible labels for form fields. Explain required inputs and errors in words, not colour alone. Keep focus visible and make menus usable with a keyboard. A decorative icon should not be the only explanation of a button’s action.
Preserve readable structure
Use headings in a logical order, adequate contrast and text that can enlarge without losing content. Describe informative images and leave purely decorative ones unannounced where appropriate. Check that sticky headers and floating widgets do not hide focused controls or important text on small screens.
Test beyond an automated score
Navigate the main journey with a keyboard and review representative pages with assistive technology. Automated tools can find some issues but cannot judge every instruction or reading order. Record problems by task and retest fixes. Use an appropriate accessibility standard when formal conformance is required.
