Bugged challenge in sass portion

Hi! i recently ran into a “bug” I think in the curriculum. so for the “Sass: Apply a Style Until a Condition is Met with @while” challenge, when adding {} to your code the whole page locks up. the page works fine until those
brackets are added. I have no idea why. I’m in chrome browser version 69.0.3497 on a 64 bit windows 10 os
3.2 ghz quad core processor with 4gb of ram and gtx 1050ti 4gb. Never submitted a bug report before so if i missed any thing pls let me know.

Thank you for helping make FCC better. Bugs should always be reported as GitHub Issues. Whenever reporting a bug, please check first that there isn’t already an issue for it and provide as much detail as possible.

thanks! it seems the problem has solved itself. going forward i will make sure to report them in the right place.
