minWidth style property

Browser support:
7
Specifies or returns the minimum width for the visible area of an element.
This property has effect only on block-level elements or on elements with absolute or fixed position. The minWidth property contains only the pure width of the visible content, without the padding, scrollbar, border and the margin. The width of an element can never be less than the value specified by the minWidth property.
Note that this property works in Internet Explorer only from version 7.
You can specify a range for the size of an element with the minWidth, minHeight, maxWidth and maxHeight properties. If you want to specify the exact size of an element, use the width and height properties.
The properties mentioned above can be used to access style settings. If you need the width of a rendered element, you can use the clientWidth, offsetWidth and scrollWidth properties or the getBoundingClientRect method.

Syntax:

object.minWidth;
