This is an experimental technology
Because this technology's specification has not stabilized, check the compatibility table for usage in various browsers. Also note that the syntax and behavior of an experimental technology is subject to change in future versions of browsers as the specification changes.
The margin-inline-start
CSS property defines the logical inline start margin of an element, which maps to a physical margin depending on the element's writing mode, directionality, and text orientation. It corresponds to the margin-top
, margin-right
, margin-bottom
, or margin-left
property depending on the values defined for writing-mode
, direction
, and text-orientation
.
It relates to margin-block-start
, margin-block-end
, and margin-inline-end
, which define the other margins of the element.
