Visually Hidden

Use the .visually-hidden utility to visually hide an element in the browser while ensuring it’s still accessible to assistive technologies, such as screen readers.

.visually-hidden {
  border: 0;
  clip: rect(0 0 0 0);
  height: auto;
  margin: 0;
  overflow: hidden;
  padding: 0;
  position: absolute;
  width: 1px;
  white-space: nowrap;
}

This is different from using the [hidden] attribute which will hide the content from both the browser and assistive technologies.
