I'm trying to remove padding between elements in accordion.
Using example: http://docs.sencha.com/extjs/4.2.1/#!/example/build/KitchenSink/ext-theme-neptune/#layout-accordion I was able to remove padding on left and right simply removing:
.x-accordion-layout-ct {
padding: 5px 5px 0;
}
EDIT: I've managed to do this part via code (adding this to Ext.define):
bodyStyle: 'padding: 0',
But I cant remove padding between elements:

I'm trying to squeeze everything so I would like those paddings to disappear.
ideally I would like to get something like this:

How can I remove rest of padding via code or CSS?
EDIT: This is version that is almost perfect (thanks to @David Thomas): http://jsfiddle.net/cPQz9/
This is CSS I've used:
.x-panel {
margin: 0;
}
.x-accordion-layout-ct {
padding: 0;
}
.x-accordion-item:not(:last-child) {
border-bottom: 1px solid red;
}
but I'm worried about browser compatibility - last selector might not work in all browsers.
