It's a blank page for me. It does not load at all.

I want my browser to display documents, not to run code. I don't want documents to be apps. The browser already has very sophisticated code to render documents well.

Unless I am really running an app - then this is somewhat fine to use the browser as a runtime. I'll make sure to only run open source apps with it, unless I really don't have a choice.

edit: wait, your page is so close to render perfectly without JS! You can fix this by avoiding opacity:0 in the HTML!
