This has been asked previously, but not for a while and things always change... Am considering focusing on one of these frameworks, not so much because I believe either might be "best", but more that many clients (especially agency clients) do seem to be expecting me to be working with one or the other.
So with that in mind...
Which one do you find yourself using more, or prefer more, and why?
I'm trying to plan ahead for the type of reasonably sized projects I've had over the past half year or so outsourced from various agencies, where they utilised a lot of elements that if I'd been using something like Bootstrap, for example, I could have "plugged-and-played" fairly easily, things such as carousels, accordions, responsive menus, tabs, and a range of other element types. It's not so much for the really simply sites.
I've been working around a few places this year and have seen BootStrap more. Only worked with Foundation once actually. I've had reservations about frameworks being heavy previously, but the columns, form and icon options are pretty handy. I especially like the 'show password' in BS, much easier than doing it by hand.
Yeah I have to say that I've worked on "work in progress" sites from agencies that were Bootstrap based on 5 or 6 occasions, versus none that were Foundation. So maybe that should be the decider on which one to spend more time with if I'm choosing one?
Again, not that it's necessarily my opinion it's "better" to use either Framework, but it's a little like working with Wordpress, it may not always be the "best" solution, but if it's what is being demanded by clients then...
Also this: "reservations about frameworks being heavy previously"
Me too. But there is some logic behind the claim that using one of the major ones means the majority of users will have the framework code already cached in their browser, if you're using one of the main CDNs for the framework.
