  • Browsers in beta stage are not supported;
  • Quirks mode is not supported. Always specify a DOCTYPE. Supported DOCTYPES include HTML5, XHTML 1.1, XHTML 1.0 (Transitional or Strict) and HTML4 Strict. Note that HTML4 Transitional triggers quirks mode;
  • Internet Explorer compatibility modes are not supported. These modes can exhibit different behavior and rendering bugs, compared to the browser versions they emulate. It is highly recommended to use IE's Edge mode via META tag or HTTP header.

    <meta http-equiv="X-UA-Compatible" content="IE=edge" />
  • Kendo UI uses progressive enhancement for its CSS styling. As a result, old and obsolete browsers may ignore CSS3 styles, such as rounded corners and linear gradients.
