As is well known, all browsers have some additional extensions for CSS features, such as `-ms-interpolation-mode`. These usually originate from properties and functions that are either not fully and explicitly defined in the CSS standard or are already completely defined in the standard but only partially supported by browsers. According to the CSS2.1 standard, all these non-compliant features must use a vendor prefix (e.g., `-ms-` for Microsoft, `-moz-` for Mozilla, `-o-` for Opera).
Below, we will introduce these extra extensions in IE8. Of course, our goal is not to carry forward those IE-only features into the next generation of web pages, but rather to take advantage of some features belonging to CSS3, where supported by the browser, to enrich our creative approaches.
