Definition max-block-size
The max-block-size property specifies the maximum size of an element in the block direction.
If the content is smaller than the maximum size in block direction, the max-block-size property value has no effect.
If the content is larger than the maximum size in block direction, the max-block-size property value will be applied.
Note: The related CSS property writing-mode defines block direction, and this affects the result of the max-block-size property. For pages in English, block direction is downward and inline direction is left to right.
The CSS
max-block-size property is very similar to CSS properties
max-height and
max-width, but the
max-block-size property is dependent on block direction.
