16 PRACTICAL GUIDES
Write documents people can navigate, zoom, listen to, and read comfortably. Practical HTML patterns for code, tables, images, and headings.
Documentation accessibility begins with the document itself. A clear heading outline, descriptive link text, and meaningful alternatives to diagrams help readers on small screens and assistive technology alike. These guides give authors concrete patterns to try and explain what to check on the finished page; a snippet by itself is not an accessibility certification.
