I'm new to front end development, and I found working with Uikit to be really easy to use. The new Uikit 3 was released yesterday and I'm having worlds of problems. Specifically, in order to use .uk-width-1-2 I now have to use .uk-width-1-2\@s I thought @'s were not allowed in CSS? Is that a media query? Where is it pulling from?

No, because certain characters are allowed if escaped by a backslash (\). The @ symbol is one of those characters, so the class .uk-width-1-2\@s is valid. More at https://mathiasbynens.be/notes/css-escapes
