Narrow UI bugs

Expected Behavior I've added some basic HTML to the "Widget description" and it looks great in my PC and my iPad. I expected to look the same in my iPhone, or if I use a narrow window in my iPad. Current Behavior In my iPhone, or if I use a narrow window in my iPad, raw HTML is shown. Also, there's a link to the standalone website in the top right corner... when I'm already in the standalone website. Possible Solution Fix your CSS for narrow screens/windows?
