insertRule method

int insertRule(
  1. String rule, [
  2. int index
])

The CSSStyleSheet.insertRule() method inserts a new CSS rule into the current style sheet.

Note: Although insertRule() is exclusively a method of CSSStyleSheet, it actually inserts the rule into [CSSStyleSheet].cssRules — its internal CSSRuleList.

Implementation

external int insertRule(
  String rule, [
  int index,
]);
