Ionic Creator 1.3.2 position fixed

ionic-v1
1

Hello

I’d like to produce the effect of a position:fixed; in creator, for a chat bubble that floats when the user scrolls. I used a button widget, and added the css :

.chat
{
    position: fixed;
    top:350px;
    right:5px;
    opacity:0.8;
    z-index:3;
}

But the chat icon doesn’t float when scrolling, it acts like any other element. Do you have any solution ?
