Vector Markup Language

Vector Markup Language (VML) is an obsolete XML-based file format for two-dimensional vector graphics. It was specified in Part 4 of the Office Open XML standards ISO/IEC 29500 and ECMA-376. According to the specification, VML is a deprecated format included in Office Open XML for legacy reasons only. VML was used extensively in MS Office 2007 Word, Excel and PowerPoint documents. In 2012, with the release of Internet Explorer 10, VML became obsolete and is no longer supported by Internet Explorer standard mode. It is a legacy feature that is available in Internet Explorer 10 only when the browser is set to run in modes that emulate the functionality of previous versions of Internet Explorer 6, 7, 8, and 9.

VML, when embedded within HTML markup, is read and processed by Microsoft Internet Explorer (but not other browsers); for example, the following example displays a solid blue oval: v\:*{behavior:url(#default#VML);position:absolute}

Microsoft Outlook HTML email rendering

Though VML is deprecated as a standard in Internet Explorer, it is most commonly used in relation to the development of HTML emails rendered in Microsoft Outlook 2007, 2010, and 2013. The use of background-images in email campaigns requires the use of VML to be displayed in Outlook because Outlook does not support the CSS or HTML attributes for background-images. However using VML for content rather than its intended purpose as an image format comes with a number of accessibility issues. v:* { behavior: url(#default#VML); display: inline-block; } v:* { behavior: url(#default#VML); display: inline-block; } Text
