A Vector Markup Language (VML) element isn't displayed in strict standards-compliant mode when an HTML page uses the !DOCTYPE element in Internet Explorer 9.

Original product version:   Internet Explorer 9
Original KB number:   932175

Resolution

To solve this problem, set the VML style to display:inline-block by using the following code:

vml\:* {
behavior: url(#default#VML);display:inline-block
}

More Information

The VML element is displayed correctly if you make sure the following things:

  • Don't use strict standards-compliant mode.
  • Remove the !DOCTYPE element.

For more information about strict standards-compliant mode, see Doctype.
