CSS - width

Description:

The width sets the width of an element's content area.

Possible Values:

length: Any length unit. Negative length values are not permitted for this property.
percentage: The width is calculated with respect to the width of the element's containing block, assuming that the containing block's width has been explicitly set.
auto: Default. The browser calculates the actual width

Applies to:

All the HTML elements except non-replaced inline elements, table rows, and row groups.

DOM Syntax:

object.style.width="100px";

Example:

Here is the example:

<p style="width:400px; height:100px;border:1px solid red;
             padding:5px; margin:10px;">
This paragraph is 400pixels wide and 100 pixels high
</p>

This will produce following result:

This paragraph is 400pixels wide and 100 pixels high
