Every librairie is called by mixin. So, you can call
@import "_core" and until you include a mixin, nothing will be output. No dependencies!
No need to install any gems.
bower install core
Well, the main idea here is that Core import some libs that we probably use everytime in our project.
So, with Core you don't have to install any gems. Everything is up to date and ready to be import.
Per example. You want to use Susy for your project. Then, your co-worker has need to work on the same project.
Until Core, he should install the gem on his computer.
If not, the compilation failed. With Core, you drop the folder
core in your project and you're good to go.
@import "_core" - everything (GetSkeleton Grid, Susy Grid, Ceaser, Custom mixins)
@import "_core/src/_susy" - Susy grid only
@import "_core/src/_ceaser" - CSS3 easing animations only
@import "_core/src/_responsive-grid" - GetSkeleton Grid only (Refer to https://github.com/theresponsiveness/GetSkeleton1200-or-960)
prefix, suffix, prefix & suffix
@include ceaser-transition(all, 800ms, $easeInQuad);
The only thing you have to do is to create susy variables and you're good to go!
