As part of WFP UI, we maintain our own bootstrap-theme.css, which is a drop-in skin for Bootstrap 3. You can find it alongside wfpui.css, under dist/css/bootstrap-theme.css.

Notice

Bootstrap theme is not a direct replacement for WFP UI. It only makes use of generic visual styles, colours, typography, and spacing, but keeps native Bootstrap components untouched, in terms of design and structure.
