ionicPopup - how to achieve a blur effect in the popup-container without blurring out the popup content?

I have a pretty basic popup with just 2 buttons - Add to Book & Favorite

Basically, its a grid of images that the user is looking at, and if they like something they can add it to their Book, or save it as a favorite.

However, I want to blur out the background and I am failing really hard at getting the background blurred. Can someone help me out?

nvm figured it out. i used ng-class on the view and gave it the blur class.

do you want something like that
you can do this many ways this is the most easy/fast
