It would be wonderful if you could lend your expertise to this, Jen; I appreciate you are busy, so any time would be good.
On Sebastian’s comment - I’m not sure I agree that it isn’t best practice; yes, ideally you should use flexbox, but there are still old versions of IE in use where this won’t work at all. I think this will make more sense in the larger context of the module:
* In the opening article of the module (currently being written by a contributor) we will review the different layout technologies available, talk about what the current state of best practice is, and set the scene for the rest of the articles.
* Then we have this article
* Then we articles on Positioning, Flexbox, and other layout stuff coming up in the near future, like Grids. I will also mention multi-col, but in my experience it is pretty weak for creating robust multiple column structures (it is only really useful for breaking up simple blocks of text). I haven’t played with it for a few years, so I will give it another spin and see if it has improved at all.
So I will be telling the whole story, over the course of the module.
