Ionic slides horizontal transition opacity ramp from 0 to 100

I have a ionic slide issue given in the link mentioned below. where the transition goes smoothly but i want the opacity (fade in fade out) to ramp from 0 to 100% while switching between slides. I have tried custom css and javascript. I have used cross fade option also. But that’s not what i am looking for. so far no luck. this is my first post. :slightly_smiling_face:
