Definition and Usage
Themax-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, themax-block-size property value has no effect.
If the content is larger than the maximum size in block direction, themax-block-size property value will be applied.
Note: The related CSS propertywriting-mode defines block direction, and this affects the result of themax-block-size property. For pages in English, block direction is downward and inline direction is left to right.
The CSSmax-block-size property is very similar to CSS propertiesmax-height andmax-width, but themax-block-size property is dependent on block direction.

}
#div2 {
