CSS min-width Property

Use the min-width CSS property to set the minimum width of the content area of an element.See property values with examples.

The min-width property sets the minimum width of an element. This property prevents the width property's value from becoming smaller than the value specified for min-width.

Note that when used together with the width and max-width properties, min-width acts as a lower bound. The computed width is clamped between min-width and max-width, overriding the width value if it falls outside that range.

The property takes a CSS length (px, pt, em, and so on), or a percentage.

Info

Negative length values are illegal.
