A simple, accessible online calculator built with HTML, CSS, and JavaScript without using any external resources.
The focus was on accessibility and use of ARIA. You can use the calculator with assistive technologies, like VoiceOver on Mac. It tested with VoiceOver with Safari, Chrome and Firefox.
It also uses some new CSS features that are broadly supported, as relative colors and nesting.
