Definition and Usage
Themargin-block-start property specifies the margin at the start in the block direction.
The CSSmargin-block andmargin-inline properties are very similar to CSS propertiesmargin-top,margin-bottom,margin-left andmargin-right, but themargin-block andmargin-inline properties are dependent on block and inline directions.
Note: The related CSS propertywriting-mode defines block direction. This affects where the start and end of a block is and the result of themargin-block-start property. For pages in English, block direction is downward and inline direction is left to right.

writing-mode: vertical-rl;
}
#myDiv {
margin-block-start: 50px;
}
