CSS Hide-and-Seek

A useful insight into visually hidden text by Gaël Poupard (translated by Hugo Giraudel)

Final snippet:

.sr-only {
  border: 0 !important;
  clip: rect(1px, 1px, 1px, 1px) !important;
  -webkit-clip-path: inset(50%) !important;
          clip-path: inset(50%) !important;
  height: 1px !important;
  overflow: hidden !important;
  padding: 0 !important;
  position: absolute !important;
  width: 1px !important;
  white-space: nowrap !important;
}

.sr-only-focusable:focus,
.sr-only-focusable:active {
  clip: auto !important;
  -webkit-clip-path: none !important;
          clip-path: none !important;
  height: auto !important;
  overflow: visible !important;
  width: auto !important;
  white-space: normal !important;
}

I think I’d use HTML attributes rather than a class, though, so it would look like this:

[hidden][aria-hidden="false"] {
  border: 0 !important;
  clip: rect(1px, 1px, 1px, 1px) !important;
  -webkit-clip-path: inset(50%) !important;
          clip-path: inset(50%) !important;
  height: 1px !important;
  overflow: hidden !important;
  padding: 0 !important;
  position: absolute !important;
  width: 1px !important;
  white-space: nowrap !important;
}

[hidden][aria-hidden="false"]:focus,
[hidden][aria-hidden="false"]:active {
  clip: auto !important;
  -webkit-clip-path: none !important;
          clip-path: none !important;
  height: auto !important;
  overflow: visible !important;
  width: auto !important;
  white-space: normal !important;
}
