CSS 2.1 Reference: clip Property

The clip property is used to specify a visible region of an absolutely positioned element. Everything outside of the specified region is hidden. The rect(top, right, bottom, left) function is used to specify the visible area as follows:

• top - offset from the top border of the element's box using a length value or the keyword auto.
• right - offset from the left border of the element's box using a length value or the keyword auto.
• bottom - offset from the top border of the element's box using a length value or the keyword auto.
• left - offset from the left border of the element's box using a length value or the keyword auto.

Note: Using the keyword auto specifies that no clipping will occur for the corresponding side.

CSS Example: The clip property is set to clip an image.

  #tst1 {clip: rect(3px, auto, 70px, 5px);
         position: absolute;
  }

• auto - no clipping will occur.
• inherit - The inherit keyword is used to specify that the value for this property should be taken from the parent element. If inherit is used with the root element, then the initial value for this property will be used.
