Not to be confused with element-style CSSStyleDeclaration.cssText.
Summary
cssText returns the actual text of a CSSStyleSheet style-rule.
Note: Can no longer be set directly, as now specified to be functionally modify-only -- and *silently* so -- meaning that attempting to set it does absolutely *nothing* -- not even warn or error. Further, it has no settable sub-properties. Therefore, to modify, 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>
