Accessibility
Our accessibility target, what we have built for it, and known limitations.
We aim for GM¹X CalcVerse to meet the Web Content Accessibility Guidelines (WCAG) 2.2 at level AA.
What we have built in
- Every calculator can be used with a keyboard alone. Search opens with Ctrl + K (⌘ K on a Mac) or the “/” key.
- All inputs have visible labels; errors are shown next to the field and announced to screen readers.
- The main result is announced politely after you stop typing, so it does not interrupt.
- Charts have the same numbers available as a table for screen readers, and long tables are scrollable with the keyboard.
- Formulas are written in MathML, which screen readers can read out, and each also has a plain-text version.
- Animation on the homepage is decorative, starts only after the page has loaded, and is switched off when your device asks for reduced motion.
- The site works when zoomed to 400% and on narrow phone screens without horizontal scrolling.
Known limitations
Live results need JavaScript. Without it, each page still shows the formula and a complete worked example so you can calculate by hand.
