As an avid user of Gist embeds, when I added the thoughtbot Sass frameworks Bourbon, Neat, and Bitters to this site, I was a bit disappointed when the widget display was a bit broken:

Incorrectly-rendered gist embed.

A bit of debugging and I found that the culprit was table-layout: fixed, which was included by Bitters. A quick patch in my main.scss file and we were all fixed: (As you can see by this working gist!)

Hope it helps somebody else. If you’d like to use progressively-enhanced Gist embeds in Jekyll like this site, check out my jekyll-gist-tag on Github! (Turn off javascript to see what this does.)
