    <!---Inspiration (and some code [all the regex]) from Ben Nadel http://www.bennadel.com/index.cfm?dax=blog:584.view--->
    
    <!---Create the local scope--->
	<cfset var local = {}>
    
    <!---This struct will hold all of the rules--->
    <cfset LOCAL.cssRules = {}>
     
    <!---
        Remove all line breaks. We are going to be doing some
        regular expressions and stripping out line breaks will
        make things slightly less complicated.
    --->
    <cfset LOCAL.strCSSData = reReplace(arguments.css_data,"[\r\n]+", " ","all") />
     
    <!---
        Strip out the CSS comments. These hold no value for us
        when we are getting the classes.
    --->
    <cfset LOCAL.strCSSData = reReplace(LOCAL.strCSSData,"/\*.*?\*/", " ", "all" ) />
    
    <!--- Create an array to hold all of the class names. --->
    <cfset LOCAL.arrClasses = ArrayNew( 1 ) />
     
     
    <!---
        Loop over the rules. Remember, each rule is now sepparated
        by a pipe (when we stripped out the {..} stuff), so we
        can loop over the rules as a pipe-delimited list.
    --->
    <cfloop
        index="LOCAL.strRule"
        list="#LOCAL.strCSSData#"
        delimiters="}">
     
        <!---
            Check to see if we still have a length (name(s)) of
            CSS classes.
        --->
        <cfif Len( trim(LOCAL.strRule) )>
        	<!---Add the item to the array--->
            <cfset arrayAppend(LOCAL.arrClasses,LOCAL.strRule) />
        </cfif>
     
    </cfloop>
    
    <cfloop array="#LOCAL.arrClasses#" index="LOCAL.each_class">
        <cfset LOCAL.cssRules[trim(listFirst(LOCAL.each_class,"{"))] = {}>
        <cfloop list="#trim(listLast(LOCAL.each_class,"{"))#" delimiters=";" index="LOCAL.each_rule">
            <cfset LOCAL.cssRules[trim(listFirst(LOCAL.each_class,"{"))][trim(listFirst(LOCAL.each_rule,":"))] = trim(listLast(LOCAL.each_rule,":"))>
        </cfloop>
    </cfloop>
    
    <cfreturn LOCAL.cssRules>
