The min-block-size property in CSS is used to create the minimum horizontal or vertical size of an element. If the writing direction is horizontal then min-block-size is equivalent to min-height property, and if it is in vertical mode then equal to min-width property.

Syntax:

min-block-size: length| percentage| auto| none| min-content| 
                max-content| fit-content| inherit| initial| unset;

Property values:

  • length: It sets a fixed value defined in px, cm, pt etc. Negative values are also allowed. Its default value is 0px.
  • percentage (%): It is the same as length but the size is set in term of percentage of the window size.
  • auto: It is used when it is desired that the browser determines the block-size.
  • none: It is used when you don’t want to limit on the size of the box.
  • max-content: It is used when you preferred min-width on the size of the box.
  • min-content: It is used when you preferred min-width on the size of the box.
  • fit-content: It is used when you preferred exact-width on the size of the box.
  • initial: It is used to set the value of the min-block-size property to its default value.
  • inherit: It is used when it is desired that the element inherits the min-block-size property from its parent element.
  • unset: It is used to unset the default mix-block-size.
