CSSRule.cssText

You’re reading the English version of this content since no translation exists yet for this locale. Help us translate this article!

The cssText property of the CSSRule interface returns the actual text of a CSSStyleSheet style-rule.

Note: 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 to be 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 for details.

Syntax

string = cssRule.cssText 

Example

<style>
  body {
    background-color: darkblue;
  }
</style>

<script>
  var stylesheet = document.styleSheets[0];
  alert(stylesheet.cssRules[0].cssText); // body { background-color: darkblue; }
</script>
