Issue here is that we're still on Bootstrap v3.x, and the upgrade to v4.x isn't just a swap it in. There's HTML changes throughout, which make it a good mini-project for a willing contributor.

@carltongibson Something that’s not 100% clear to me. Are we okay with the jQuery update we’ve made?

[lovelydinosaur]

I guess so, since it oughta be backwards compatible

[carltongibson]

Yeah... I believe so. Bar some dropping of browsers we don't support jQuery hasn't broken anything for a long while.

@carltongibson -- I'd be willing to have a go at this if you think I have the skills (It is 'just' template layouts and bootstrap right...).

kind of yes.

@smithdc1: yes, it’s exactly that. Updating the Browsable API templates to use the newer version. (I didn’t look into it but I see v5 is on the way — don’t know if it’s worth skipping straight to that?)

Yes v5 in alpha and a few alpha releases expected over the coming months weeks/months, my guess is v5 will be out in Q4. The main thing with v5 is it no longer depends upon jQuery. The upgrade from v4-v5 should be much easier than v3-v4.

I'll go investigate.

On the topic of updating themes... What about the docs, they seem to be on bootstrap 2?
