Definition and Usage
The margin-block-start
property specifies the margin at the start in the block direction.
The CSS
margin-block
and
margin-inline
properties are very similar to CSS properties
margin-top
,
margin-bottom
,
margin-left
and
margin-right
, but the
margin-block
and
margin-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 margin-block-start
property. For pages in English, block direction is downward and inline direction is left to right.

More Examples
Example
With the writing-mode
property value of a <div> element set to vertical-rl, the block direction is right to left. The result is that the start of the element is moved from top to right side. So, a change in writing-mode
also changes the effect from margin-block-start
:
#parentDiv {
writing-mode: vertical-rl;
}
#myDiv {
margin-block-start: 50px;
}
