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).

• 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.
