This property sets the width of an element's content region (excluding padding, border, and margin). Standard length units can be used and pixels (px) is often the assumed measurement in browsers. Percentage values, based on the width of the containing element, can also be used. The default value of auto automatically calculates the width of an element, based on the width of the containing element and the size of the content.


p {width: 400px; padding: 10px; border: solid 5px;}
