We should change the media queries we use for field containers from min-width 450px to 30em.
I forgot to mention that if we are going to use a class to opt-in MQ's for tables and other responsive features, we should also do the same for field containers.
[Fieldcontain] - Changed from 450px to 28em breakpoint. Fixes #5276
This does tweak the current breakpoint by a few pixels for round
numbers: 450px divided 16px = 28.125em
@uGoMobi - I set the breakpoints to 28em, not 30em since 450px divided by 16px = 28.125.
I was going to add the "ui-responsive" class and selector but it seems like the data-role="fieldcontain" is pretty mush the same opt-in to this breakpoint as applying a new class. If you want, we could add the new class selector but maybe just deprecate the data-role="fieldcontain" for 1.3 and drop it in 1.4. Seems like adding a breaking change for such a popular feature strictly for consistency isn't a great tradeoff. Let's discuss that more and open a new ticket if we want to do this.
When I wrote that I was thinking about using the same one or two breakpoints for all widgets and you mentioned 30em (480px) for tables as one of them. As discussed we are not going to use generic breakpoints, so make sense to use 28em here.
I agree that making changes to this feature, just for the sake of consistency is not a good idea. That was not the main reason for suggesting an opt-in class for fieldcontain as well. It's more like, if we introduce this for other widgets it's a good opportunity to do the same here, because it's not easy to negate the fieldcontain CSS if you want to use a different breakpoint.
However, I see your point that adding data-role="fieldcontain" is pretty much the same as adding an opt-in class. Difference is that I added a function to the fieldcontain JS that prevents wrapping of full width forms, so it's not only CSS.
Let's see if we can come up with a solution that doesn't break things when used with current markup.
@uGoMobi - Makes sense. I have been using unique media queries for each widget, but only providing one option via the "ui-responsive" class. If you can come up with a system that doesn't break older markup, that would be ideal. The full width form elements is a wrinkle I hadn't thought of.
BTW - your fieldcontain test pages in /demos/ were really helpful when working on this. It caught a CSS mistake I made right away.
