-moz-float-edge

Non-standard
This feature is non-standard and is not on a standards track. Do not use it on production sites facing the Web: it will not work for every user. There may also be large incompatibilities between implementations and the behavior may change in the future.

The non-standard -moz-float-edge CSS property specifies whether the height and width properties of the element include the margin, border, or padding thickness.

/* Keyword values */

-moz-float-edge: margin-box;
-moz-float-edge: padding-box;

/* Global values */
