I'm having trouble getting this to work. JSFiddle: http://jsfiddle.net/JohnSmith593/ku313fpn/

on my wikia...
 * css: http://wurm-almanac.wikia.com/wiki/MediaWiki%3ACommon.css
 * js: http://wurm-almanac.wikia.com/wiki/MediaWiki%3ACommon.js
 * js: http://wurm-almanac.wikia.com/wiki/MediaWiki%3AFence_slope.js
 * calculator page: http://wurm-almanac.wikia.com/wiki/Fence_slope_calculator

Q: Wikimedia seems to indicate that Jquery and Jquery-ui should already be available and do I need to do something so I can access the slider widget?

Q: Are there any good written works that explain how to use JS, CSS, HTML with Wikimedia? There are plenty out there that describe JS, CSS, HTML but I'm having trouble finding things that explain interaction with Wikimedia.

Q: My MediaWiki:Common.js doesn't seem like the best way to get this to work. I believe it should only run the importArticles if a page has the template. Is this a good idea and any tips would be appreciated.
