CSS set style to the parent of class="something" tag

itemprop="text">

I have this in my HTML
file:

            
someText
             class="something">otherText





Is
there a way in CSS I can set the background of the PARENT of the class named something?
In this case, the tag?

Here is my
code:

             type="text/javascript">
 function MyMethod(sender, eventArgs) {

            if (condition) {
 app.set_cssClass("MyClass");
 }

            $('.MyClass').parent().css('background', 'url(Images/star.png) no-repeat')

            }
