Cannot use .btn-success, .btn-info, .btn-danger, .btn-warning classes in conjunction with .button class

.button class is used for compatibility reasons with Colibri skin.

In Colibri we had just 2 styles for buttons (primary and secondary) while in Bootstrap there are more (primary, default, succes, info, danger, warning).

When using in conjunction both .button and .btn-success for example, because of the way we declared the properties, the cascading wins for the .button styles. So instead of having a green button, we have a blue one.
