Slider height

Slider height

Hi,

I have no idea why the slider control I have in my mobile site does not fit with the rest of the controls.  I have tried everything to get it to match the same size as the other controls.  Changed the theme, placed it in a control group, tried to apply a style height to it, and nothing works.  The height of the slider does not change.

How do I get the slider height to change to match the other controls in my site?
