Css Inset Example
The inset CSS property is a shorthand that corresponds to the top, right, bottom, and/or left properties. It has the same multi-value syntax of the margin shorthand.
While part of the CSS Logical Properties specification, it does not define logical offsets. It defines physical offsets, regardless of the element's writing mode, directionality, and text orientation.
/* <length> values */
inset: 10px; /* value applied to all edges */
inset: 4px 8px; /* top/bottom left/right */
inset: 5px 15px 10px; /* top left/right bottom */
inset: 2.4em 3em 3em 3em; /* top right bottom left */
/* <percentage>s of the width (left/right) or height (top/bottom) of the containing block */
inset: 10% 5% 5% 5%;
/* Keyword value */
inset: auto;
/* Global values */
inset: inherit;
inset: initial;
inset: unset;
