See: <https://jsfiddle.net/8osg70fp/>

I have an image on the right-hand side of the page that I want to scale like in the fiddle, when a div on the opposite side is hovered on.

I know its something along this format, but I cant get it to work.

```
var treecontainer=document.getElementById('treecontainer'); //DIV=TREECONTAINER
$(treecontainer).mouseover(function(){
    /*CHANGE IMAGE'S CSS HERE*/    
});
$(treecontainer).mouseleave(function(){
    /*CHANGE IMAGE'S CSS BACK HERE*/    
});

```
