As part Theme Revamp, this page is to discuss, and plan an eventual transition to using Bootstrap in Tiki. As there is a general consensus we should move in the general Bootstrap direction (the minimum being the ability to use Bootstrap themes), the remaining questions are no longer "if" but more "how" and "when"
Do we go for a clean break / "burn all bridges" approach and force major changes on all legacy themes? or do we make an effort to try to make old themes still work?
Arguments for clean break
End result will be simpler code
End result will be closer to what people already know (people that use Bootstrap that is)
Most theme intense sites have more than enough features in the LTS versions and can use that until they decide to refresh their site design.
Arguments for legacy support
Makes it easier for heavily customized themes to upgrade
Things to watch out for
Things that Bootstrap doesn't cover
Logo?
Presumably, Tiki's HTML classes will be a superset of the Bootstrap classes, so our current method for specifying the logo can still be used, in combination with the benefit of Bootstrap's layout.
RTL is not in v2
Licensing issue prevents us use Bootstrap 2 anyway
True, but Tiki's templates and CSS really need a major overhaul anyway. If that happens in a way that can take advantage of the Bootstrap bandwagon (as long as we still have design flexibility), so much the better.
In version 3.0
No set release date, but probably sometime in 2013
