min-width property CSS Reference

Definition and Usage

The min-width CSS property is used to set the minimum width of a given element. It prevents the used value of the width property from becoming smaller than the value specified for min-width.

The value of min-width overrides both max-width and width.

• Initial 0
• Applies to all elements but non-replaced inline elements, table rows, and row groups
• Inherited no
• Percentages refer to the width of the containing block
• Media visual
• Computed Value the percentage as specified or the absolute length
• Animatable yes, as a length, percentage or calc(); when both values are lengths, they are interpolated as lengths; when both values are percentages, they are interpolated as percentages; otherwise, both values are converted into a calc() function that is the sum of a length and a percentage (each possibly zero), and these calc() functions have each half interpolated as real numbers.
• Canonical order the unique non-ambiguous order defined by the formal grammar
