Offscreen

Hides an element completely (visually and positionally) in the DOM while still allowing it to be accessible.

• Remove all borders and padding and hide the element's overflow.
• Use clip to define that no part of the element is shown.
• Make the height and width of the element 1px and negate them using margin: -1px.
• Use position: absolute so that the element does not take up space in the DOM.
• Note: This technique provides an accessible and layout-friendly alternative to display: none (not readable by screen readers) and visibility: hidden (takes up physical space in the DOM).
