This theme is mostly equivalent to
bootstrap3, with the optional
bootstrap-theme.min.css file in use. According to the Bootstrap
developers, it provides a visually enhanced experience, with gradients
(hence the name), resembling Bootstrap 2.x.
(bootswatch IS NOT compatible with this theme. Attempting to use both will lead to a broken, mixed theme in which most things affected by bootswatch will be replaced by bootstrap-theme’s creations)
You can report issues with this theme and request help via GitHub Issues (themes repository).
