Cortex Plus Dice Pool Roller App as character sheet code snippet

Hey there. Old gamer, relatively new to Roll20, very new to HTML, CSS, etc. I'm an old C programmer from way back, so hopefully my code isn't too coarse. We're currently playing Cortex Plus (Marvel Heroic, specifically) and it really works best with a flexible dice pool picker. We all migrated here after just such a tool was dropped from Google Hangouts. Loving the venue here, but dice rolling has been a bit rough. I've coded up a dice tool as a character sheet, as well as a version that can be added to any character sheet and shows up as a tool bar across the top. Here to ask 2 things: 1. I'd like some guidance as to whether I've broken any coding standards too badly. Is there a way to post the code for review and is this the right forum? 2. I'm completely unskilled at github, and would like some help providing this to others. There's a community looking for this solution... Thx!

I am currently working on a cortex sheet (along with three other projects), and the working copy is  here .  Maybe this will help.  In any case, all advice in appreciated. 

Looks like a Cortex Classic implementation? Never played, but I recognize the constructs. We're mostly playing Cortex Plus Heroic (usually Marvel Heroic Roleplaying), which has some complex dice pool elements I'm working on implementing.  I'll take a look at yours and let you know if I have any comments, although at this point all I'm likely to be able to spot is the occasional typo...
