The included function works perfect in Firefox, IE, and Safari but returns Cannot Read Property Length for rules.length.
I have spent a couple hours on this one and before going crazy I thought I would pose my question here hoping someone might have a solution . I have tried several but none work so far.
Thanks In Advance
// set the value of a property of a CSS Rule
function changeClassProperty(sClassName,sProperty,sValue) {
  sClassName="."+sClassName;
  var sheets = document.styleSheets;
  var rules;
  var styleObj;
  for (i=0;i< sheets.length; i++) {
    rules=sheets[i].cssRules;
        if (!rules)
    {rules=sheets[i].rules;}
    for (var j=0; j<rules.length; j++) {
      if (rules[j].selectorText && rules[j].selectorText==sClassName) {

        styleObj=rules[j].style;
        styleObj[sProperty]=sValue;
        break;
      }
    }
  }
}

Seems to be working now. Not sure if there were caching issues at my home computer but loaded it up in chrome at my shop and all is good. So the Stackoverflow solution seemed to do the trick..
Thanks
