+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).
