You didn't import the new JS/CSS pages. Only certain JS/CSS pages are loaded automatically. The rest have to be loaded by importing them via the ones that are automatically loaded. Also, I noticed that in MediaWiki:Wikia.css, you have a regular CSS rule above two @import rules. The @import rules must be above the regular rules or they won't work. So, for instance, right now your import of MinimalistSlider is also not being executed.
