I should have stressed that we only need/want a minimal demo – as in, just enough HTML and CSS to illustrate the immediate problem you’re having. We don’t need to see everything.
Unfortunately, folks wont want to sift through an almost 4000 line CSS file to work out which parts relate to what. Its just too overwhelming for us when we’re browsing in our spare time.
Demos that are least likely to scared potential helpers off usually consist of a handful of elements, and less-than 40 lines of CSS. The fewer lines, the better.
