Using ProStyles Master Styles
Master styles allow you to specify a style for buttons once and re-use that style throughout your page.
Styling all the items in a ButtonBar menu is quick and easy with ProStyles. Changes to color, text and other styles are instantly applied to the entire menu.
A ProStyles master though is very different to just making a partial of your button but the two are not mutually exclusive.
Make a partial button with a site wide link and then style it using a ProStyles master. Color scheme changes can then by synchronised between normal buttons and partial buttons easily.
