SubView and CSS ID selectors

[Kevin]

Hello,

Using a <f:subview/> within my layout like below:

<t:div id="ID_one">
                            <f:subview id="ID_two">
                              <t:div id="someId">
                                        some content...
 </t:div>
                            </f:subview>

                        </t:div>


results in  an HTML id of "ID_one:ID_two".

I seem unable to style this with CSS using something like:

#ID_one:ID_two{}

or

#ID_two{}


I can style it with a class but I actually need to style it and access 
with JavaScript. Does anyone have any suggestions?

Thanks in advance,

Kevin
