Accessibility

How this site aims to meet WCAG 2.1 AA, and how to report a barrier.

We want this site to work for everyone. It aims to meet the Web Content Accessibility Guidelines (WCAG) 2.1 at level AA: text has sufficient contrast, everything works by keyboard, images have text alternatives, and animations are turned off when your device asks for reduced motion.

The homepage “notebook” reveals its outputs as you scroll. All of the text is in the page from the start, so screen readers and search engines see everything, and the Run all button shows every output at once.

If you meet a barrier on this site, or need a document in another format, please write to ryan.oloughlin [at] qc.cuny.edu. We will do our best to help.
