I am trying to use javascript to insert css rules within css classes. However I am only finding that my code only succeeds in prepending a new class and rule, while NOT inserting a new rule within a desired predefined css class. eg:

<style type="text/css">

a1.inner {
          position: relative;   
          display:  block;
          width:    100px;
          height:   100px;
          left:     -1px;
          top:      -1px; 
          border:   solid black 1px;
                
	 }

a2.outer {
          display:  block;
          width:    350px;
          height:   100px;  
          border:   solid black 1px;
          overflow: hidden;
         }

a3.inner {
          position: relative; 
          display:  block;
          width:    141.42px;
          height:   141.42px;
          left:     -1px;
          top:      -1px; 
          border:   solid black 1px;  
         }

a4.outer {
          display:  block;
          width:    100px;
          height:   100px; 
          border:   solid black 1px;
          overflow: hidden;
         }
</style>


document.styleSheets[0].insertRule('a1.inner{-moz-transform:rotate(45deg);}',cssRuleEndIndex);


How do I insert/read/update a new selector:value; rule in a specified css class? Is there a way to "create"/set/get css properties and values, within css classes, in a multiple platform way, particurly if css has already been defined in javascript or a css style block like this one?

You probably need to add a new stylesheet with that rule after the last stylesheet.
