CSS - inset-inline Property

The CSS property inset-inline determines the logical start and end offsets of an element in the inline direction. It depends upon the writing mode, direction and text orientation of the element. It relates to the top and bottom, or left and right CSS properties, for the physical offsets.

It is a shorthand property for inset-inline-end and inset-inline-start CSS properties.

Possible Values

The CSS property inset-inline takes the same set of values as left CSS property, which are as follows:

  • <length> − Can specify a negative, null or positive value.

  • <percentage> − Percentage of the container's width.

  • auto − Default value. Browser calculates the left position.

  • inherit − Specifies the same value as computed from its parent element.

Applies To

All positioned elements.

Syntax

inset-inline = <'top'>{1,2}  

/* <length> values */
inset-inline: 5px 10px;
