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: border-box; -moz-float-edge: content-box; -moz-float-edge: margin-box; -moz-float-edge: padding-box; /* Global values */ -moz-float-edge: inherit; -moz-float-edge: initial; -moz-float-edge: unset;
| Initial value | content-box |
|---|---|
| Applies to | all elements |
| Inherited | no |
| Media | visual |
| Computed value | as specified |
| Animation type | discrete |
| Canonical order | the unique non-ambiguous order defined by the formal grammar |
