CSS min-block-size Property


Example

Set the minimum size of a <div> element to 200 pixels in the block direction:

div {
  min-block-size: 200px;
}
Try it Yourself »

More "Try it Yourself" examples below.


Definition and Usage

The min-block-size property specifies the minimum size of an element in the block direction.

If the content is smaller than the minimum size in block direction, the min-block-size property value will be applied.

If the content is larger than the minimum size in block direction, the min-block-size property value has no effect.

Note: The related CSS property writing-mode defines block direction, and this affects the result of the min-block-size property. For pages in English, block direction is downward and inline direction is left to right.

The CSS min-block-size property is very similar to CSS properties min-height and min-width, but the min-block-size property is dependent on block direction.

More Examples

Writing mode

With the writing-mode property value of a <div> element set to vertical-rl, the block direction is changed from downwards to sideways, and this affects how the min-block-size property work:

div {
  min-block-size: 200px;
  writing-mode: vertical-rl;
}

Min-block-size vs Block-size

See how one <div> element with block-size 100px, and another <div> with min-block-size 100px, react differently with changing content size:

#div1 {
  min-block-size: 100px;
}
#div2 {
  block-size: 100px;
}
