The following is a guest post by Filip Naumovic from Salsita Software. Filip has built a Sass tool to help with an issue I know I've experienced many times. You're happily nesting in Sass. You're maybe a level or two deep, and you need to style a variation based on some parent selector. You need to either break out of the nesting and start a new nesting context, or go nuclear with
@at-root. I'll let Filip tell the story of his new tool that changes that.
& is an extremely useful feature in Sass (and Less). It's used when nesting. It can be a nice time-saver when you know how to use it, or a bit of a time-waster when you're struggling and could have written the same code in regular CSS.
Let's see if we can really understand it.
