Nick: I scraped the DOM and the dependent stylesheets from the character sheet window via web inspector and saved them locally. I then use the saved HTML as part of my custom character sheet during development on a local server. Basically just make sure that your HTML is all a child of the div classed "charsheet". This provides the basic framing window and the basic styles from what looks to be jQueryUI, Bootstrap, and other. I'm using Visual Studio 2015 so all this pretty much just making a web project out of the roll20-character-sheets directory that I check out from git. This doesn't allow you to do anything with repeating rows or auto-calculating fields of course. Doing it locally also allows you to use a CSS preprocessor (which I can't live without). :) I've zipped up my mock page and CSS from the above here if anyone wants it. I scraped this back in the beginning of February so it's possible the CSS might be a bit out of date, but I'm still using these and it seems close enough. <a href="https://onedrive.live.com/redir?resid=8DD0F0BFC88D" rel="nofollow">https://onedrive.live.com/redir?resid=8DD0F0BFC88D</a>... Just remember to remove all the HTML surrounding your custom character sheet before pushing your changes up!
