Completely hides an element visually and positionally in the DOM while still allowing it to be accessible. Provides an alternative to display: none (not readable by screen readers) and visibility: hidden (takes up physical space in the DOM).

.offscreen {
  border: 0;
  clip: rect(0 0 0 0);
  height: 1px;
  margin: -1px;
  overflow: hidden;
  padding: 0;
  position: absolute;
  width: 1px;
}

Explanation

• Remove all borders.
• Use clip to indicate that no part of the element should be shown.
• Make the height and width of the element 1px.
• Negate the elements height and width using margin: -1px.
• Hide the element's overflow.
• Remove all padding.
• Position the element absolutely so that it does not take up space in the DOM.
