The min-width CSS property is used to set the minimum width that an element can have. It ensures that the element’s width will not be smaller than the specified value.

The min-width property accepts various length units, such as pixels (px), percentages (%), viewport width (vw), or the auto keyword.

Here’s an example:

.container {
  min-width: 300px;

In this example, the .container class sets a minimum width of 300px for the element. If the content inside the element requires more space, the width of the element will expand accordingly.

You can also use other length units or percentage values to set a relative minimum width:

.container {
  min-width: 50%;

In this case, the .container class sets a minimum width of 50% of its containing element’s width. This allows the element to dynamically adjust its width based on the available space.

The min-width property is useful when you want to ensure that an element always has a minimum width, even when its content is sparse or absent. It helps maintain consistent proportions and prevents elements from becoming too small.
