Need a script for user password change

[DGrandes]

OK, The top bar I have also in safari when making add to home screen and there is no way to hide it. The bottom bar is to be bale to navigate back to app otherwise you will be lock in it.  Technically it could be removed in new app but a new app would need to be created.  This takes long time as it needs certification.

OK, 

but in home screen shortcut of shafari I change the color and it seems that it is part of the application.

   

Is there any way to change top and bottom bar color?

Thanks
