Definition and Usage
The inset-block property sets the distance between an element and the parent element in the block direction.
Note: For this property to take effect it has to have the position property specified.
The inset-block property is a shorthand property for the following properties:
Values for the inset-block property can be set in different ways:
If the inset-block property has two values:
- inset-block: 10px 50px;

- distance at end is 50px
If the inset-block property has one value:
- inset-block: 10px;
- distance at start and end is 10px
The CSS
inset-block and
inset-inline properties are very similar to CSS properties
top,
bottom,
left and
right, but the
inset-block and
inset-inline properties are dependent on block and inline directions.
Note: The related CSS property writing-mode defines block direction. This affects where the start and end of a block is and the result of the inset-block property. For pages in English, block direction is downward and inline direction is left to right.
