overflow-y not working in safari inside a modal

Answer 1

Check Your Version of Safari Browser. And match with criteria given below :

1. Available in Safari 3.0 and later.
2. Available in iOS 1.0 and later.

if you're against the conditions then get upto following measures:

1. Apply ClearFix

   .clearfix:after {visibility: hidden;}

Reason: Setting overflow doesn't clear the float at the element

OR

2. Set Position of element relative at root/body level like this :

   body { position:relative; overflow-x:hidden; }

Note: Apply only one of them.

Thanks & cheers
