cssText 特性为 CSSRule interface returns the actual text of a CSSStyleSheet style-rule.

注意： Do not confuse this property with element-style CSSStyleDeclaration.cssText .

Be aware that this property can no longer be set directly, as it is now specified 到 functionally modify-only, and silently so. In other words, attempting to set it does absolutely nothing , and doesn't even omit a warning or error. Furthermore, it has no settable sub-properties. Therefore, to modify it, use the stylesheet's cssRules [index] properties .selectorText and .style (or its sub-properties). See Using dynamic styling information 了解细节。

句法

string = cssRule.cssText

<style>
  body {

  var stylesheet = document.styleSheets[0];
