Microsoft CSS Extensions are extensions created by Microsoft which support a number of extensions to CSS that are prefixed with -ms-. Some of these properties have been proposed for inclusion in the CSS specification, though the standard property may be different from the -ms- implementation. Some of these non-standard properties apply only to elements with XUL display types. There is one property without the -ms- prefix which is a Microsoft extension, it is accelerator.
