I started the css-colors lesson. I was on Exercise 2, when I messed up and reset it. Ever since then the Web Browser window to the right of the screen remains blank. The top of the window reads "http://localhost:8000", but nothing loads into the window. If I hit the back arrow on the browser window, the small "loading" circle constantly cycles. Nothing happens.
I can complete the lesson fine, but I am unable to see what I am doing with each adjustment in the script because the browser window remains blank.
Replace this line with your code.
