You explain something about Mixins/LESS here:
Am I right Mixins has nothing to do with Twitter Bootstrap Library?
Mixins is something made possible by LESS right?
Mixins allow you to embed all the properties of a class into another class by simply including the class name as one of its properties. It’s just like variables, but for whole classes. Mixins can also behave like functions, and take arguments, as seen in the example below.
But you also integrated Twitter Bootstrap Library into Pagelines. What I think I figured out right now, is that all the nice Twitter Bootstrap stuff > Pagelines made MIXINS of it....
Am I right?
Because I found out today this is also working (and this is same behaviour like MIXIN):
An other question I have is about the Icons. What is the difference between the icons I see on the Twitter Bootstrap Page and the Font Awesome page?
And why is Pagelines using 'em' instead of 'i' what I see on Twitter Bootstrap and Font Awesome page?
The new icon font system in PageLines 2.3 makes adding icons to elements easier than ever before. The best part is that its fully backwards compatible with the existing icons found in Bootstrap.
Hope to hear from you soon.
