forever and ever is a very long time;

Hey everyone! Are any of your scribbld/CSS savvy? I'm trying to customize my journal (in S2, with the "Dear Diary" layout) with the CSS here. I followed the directions, and I can save changes when I only change the option to not use the layout's stylesheet, but after I paste the custom stylesheet into the box and click "save changes" again, the operation times out in IE and loads a blank page in Firefox. I wonder if this is problem on my end? I had no problem customizing in S1. D: Should I try to find somewhere to host the stylesheet and upload it from a URL?

Thanks for any help in advance!
