{{ CSSMozExtensionRef() }}
Summary
-moz-box-sizing
is used by mozilla browsers to alter the default CSS box model used to calculate widths and heights of elements. It is possible to use this property to allow mozilla to emulate the behavior of browsers that do not correctly support the CSS box model specification, though this is not recommended as most standards-compliant browsers do not support this property.
