Hi Steven,
Most probably the two versions (v3 and v2) will be in conflict if you load them at the same time. But you can try.
You said "
There are so many new and cool additions..." - well, I'm not sure I understand what you mean.
There's almost nothing new in
UIkit v3 compared to
UIkit v2.
The framework was just reorganized and was made even more modular.
Almost everything that you see in v3 is already available in v2 (or can be achieved by combining components).
1. Responsive Columns - they are available in
v2 as well.
2. Background - hmm, those are just utility classes. Just write your CSS in the
custom.scss file.
For example, instead of using the
uk-background-fixed
and
uk-background-cover
classes, just write the following code in your custom.scss file:
.yourElement {
background-attachment: fixed;
background-size: cover;
}
3. Card - the equivalent in v2 is
Panel. Or you can just write your own HTML and style it via the
custom.scss file.
Here, have a look at
this discussion in order to see what our plans for UIkit are.
However, I do not see us updating to UIkit v3 in the next 5-6 months.
UIkit v3 is still in beta (yep, it is pretty stable but it is indeed in Beta and some of the components that we use the most are still missing).
Once the framework gets out of Beta, we do need to wait for couple of months so all the bugs are fixed.
