VML is no longer supported

Vector Markup Language (VML) is obsolete in Internet Explorer 10 (quirks and 10 document modes).

For Internet Explorer 10, VML will not work (is obsolete) in the following document modes:

The common uses of VML now have standards-based alternatives implemented in Internet Explorer 10 and current versions of other browsers. This legacy Windows Internet Explorer features remains available in Internet Explorer 10 in document modes 5, 7, 8, and 9 though their performance is inferior to their hardware-accelerated, standards-based replacements. We encourage web developers to move their sites to standards-based technologies rather than relying on legacy document modes.

SVG, implemented in Windows Internet Explorer 9, provides the functionality needed to replace VML in websites and applications that use it. The VML to SVG Migration Guide, published on the Microsoft Download Center, provides guidance for moving from VML to SVG.
