If this is for the challenge, try deleting the code and completely re-writing it. I noticed on some challenges Workspaces didn't read my code properly and completely re-writing it worked. Also, I believe there should be a space after the colon for text-decoration. It should look like this:

a { text-decoration: none; }

I hope this helps!

Hey Brandon,

You are right about sometimes the challenge does glitch and needs to be refreshed. And, just for your reference about the space after the colon, that is entirely up to you. It can be there, but it doesn't have to be. Personally, I like there, because it makes it easier to read, but when you minify your CSS, the space is taken out.

Keep Coding! :)
