A settings reveal that I made ages ago when I was still new to this, converted to Slim and Sass.
Here is my write-up from back then (looking back, the gear icon was supplanted by hamburger lines, which I'm also cool with):
"I don't love the settings gear as an icon. It is a universal standard at this point, it so should really be used when possible. Were it not the standard, however, I can think of some nicer alternatives.
One alternative that I like is the nut. It scales better and is less visually intrusive.
In the demo, I've got a pure CSS nut that unscrews itself and drops the curtain on a hover event. This could be used to reveal the settings for a page.
Though this should really be a click event, I've used :hover to be a no-JS ninja."
