Widgets have inconsistent visual style

The visual style of the widgets is inconsistent in several places the main one being border color. Many of the widgets do not use the default border color on the outer widget and instead use the content border color ( slightly lighter ). This would seem to be semantically incorrect ( shouldn't all widgets use the default boder color by default? ) and is also inconsistent with what is done natively.

Spinners and buttons are a good example nativly a spinner and a button are the same height and have the same border color but the button widget uses the defautl border color while the spinner widget uses the content border color, the button widget is also much taller then the spinner widget. We should give all the widgets a consistent style.

Side note: apparently the icons are missing on the cdn for the git build
