css - Can I merge Bootstrap 2.3.1 with new versions like 4.0 or 3.x.x? -


i have website in used bootstrap 2.3.1. want change version , want update. if updated bootstrap new version. total ui changing. website turning clumsy. intention merge previous bootstrap file new 1 without removing previous attributes , updating new content.

yes, can. don't want it. merging both bootstraps cause hardly maintainable mess , conflicts (one behavior overwriting another). surely it's doable, couple more imports of new bootstrap , there have it.

i try solve without merging different bootstraps, though! here's how:

if project small, maybe it's idea migrate new bootstrap , rid of old one.

if project big, use new bootstrap in new views, while leaving old views use old bootstrap untouched. if have time , resources, rewrite/migrate these old views 1 one using new bootstrap. idea not use both bootstraps on same view @ same time, rather switch new bootstrap chosen views.

good luck!
