Mark the Current Page in Menus Built With Blocks and Widgets
Adds aria-current="page" to any link on the page that points to the page being viewed, for menus, widget link lists and footer links that do not mark it themselves.
Snippet Library
Accessibility snippets for WordPress
Snippets that make WordPress easier for everyone to use: skip links, focus styles, better link text and fixes for common accessibility issues. For site owners who want a site that works with keyboards and screen readers.
Readable Tag Cloud Sizes
Keeps the smallest tags in tag cloud widgets and blocks large enough to read and tap, and sizes them in relative units so they grow with the visitor's text size.
Use Real Headings for Widget Titles
Makes classic sidebar widget titles proper H2 headings, so screen reader users can jump between widgets with heading navigation.
