The html5 player in iOS is very small and it is very difficult to press play pause buttons etc...
It would be convenient that when the type is audio, create a custom audio player with play, pause, etc. controls instead of showing the native html5 one
iOS player in html5 native only can be edited the color not size, form etc...
Really is too difficult to do click on mobile devices.
Android can make bigger using css but design is also bad.
