This is what’s often (OK, almost always) missed with such JavaScriptless components: progressive enhancement with JavaScript, so that it works without JavaScript, and works better with just a little JavaScript. Most of the traditional CSS hacks can be made just as good as the JavaScript version designed with accessibility in mind without too much effort. Most of the time it’s just managing some ARIA attributes and no more. Occasionally you might add an extra supporting element or slightly restructure an existing one.
