CSS max-block-size Property

❮ Previous Reference Next ❯

Example

p {
  background-color: #1A73E8;
  max-block-size: 150px;
}



writing-mode:





Lorem Ipsum is simply dummy text of the printing and typesetting industry.

Meaning:

The max-block-size CSS property specifies the maximum size of an element in the direction opposite that of the writing direction as specified by writing-mode.

That is, if the writing direction is horizontal, then max-block-size is equivalent to max-height; if the writing direction is vertical, max-block-size is the same as max-width.

Note: The other dimension's maximum length is specified using the max-inline-size property.

This is useful because the max-width is always used for horizontal sizes and max-height is always used for vertical sizes, and if you need to set lengths based on the size of your text content, you need to be able to do so with the writing direction in mind.
