/* <length> values */ margin-block: 10px 20px;  /* An absolute length */ margin-block: 1em 2em;    /* relative to the text size */ margin-block: 5% 2%;      /* relative to the nearest block container's width */ margin-block: 10px;       /* sets both start and end values */  /* Keyword values */ margin-block: auto;  /* Global values */ margin-block: inherit; margin-block: initial; margin-block: revert; margin-block: unset; 

margin-block

The margin-block CSS shorthand property defines the logical block start and end margins of an element, which maps to physical margins depending on the element's writing mode, directionality, and text orientation.

/* <length> values */ margin-block: 10px 20px;  /* An absolute length */ margin-block: 1em 2em;    /* relative to the text size */ margin-block: 5% 2%;      /* relative to the nearest block container's width */ margin-block: 10px;       /* sets both start and end values */  /* Keyword values */ margin-block: auto;  /* Global values */ margin-block: inherit; margin-block: initial; margin-block: revert; margin-block: unset; 

This property corresponds to the margin-top and margin-bottom, or the margin-right and margin-left properties, depending on the values defined for writing-mode, direction, and text-orientation.
