CSS min-width Property

❮ Prev Next ❯

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.

Meanwhile, the min-width property overrides width property and CSS max-width property.

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

Negative length values are illegal.
