HTMLStyleElement.type

The HTMLStyleElement.type read-only property returns the type of the current style.

For Gecko, the type is most often given as "text/css." From the W3C spec on CSS: "The expectation is that binding-specific casting methods can be used to cast down from an instance of the CSSRule interface to the specific derived interface implied by the type."

Syntax

string = style.type;

Example

if (newStyle.type != "text/css"){
   // not supported!
   warnCSS();
}
