Hiding element on mobile

Hi, 

I'm trying to hide the top green element with this code and it's not working:

@media only screen and (max-width: 768px) {
 #yui_3_17_2_1_1603186140780_94 
  {
   display: none; 
 }
}

Any suggested solutions?

#yui id's are not constant, and cant be used

You will need to find a parent element with #block id and then target the child element with that.

#block-id_____________ .child .child
