re: Create an accessible dropdown navigation VIEW POST


I'd probably still use the CSS method, I try to avoid JS where I can, if I could and have your method as a backup in case focus-within wasn't supported.

try {
} catch (err) {
  console.log("focus-within is not available, using polyfill");

function focusWithinFallback(array) {
  array.forEach(link => {
.menu__item:hover .submenu,
.menu__item:focus-within .submenu,
.menu__item.focus .submenu {
  padding: 0.5rem 0;
  width: 9rem;
  height: auto;
  background: #eedbff;
  clip: auto;

This would give you support back to IE6 😀
Unparsable CSS is ignored by default.

I'm a front-end dev, I am aware that unparsable CSS is ignored by default ;)

It was more for people that might read later 😜

Yeah, I definitely understand the avoiding JS by default mindset. For me, I usually think this way too. My rule of thumb is always to use JS to toggle classes and use CSS to change the styling vs control the styling in JS. Over the years though, I've been less resistant to use JS depending on circumstance so long as I'm writing it in a minimalistic style.

I'll play around more with :focus-within for my follow up post :).
