I thought I'd try the new hamburger in email hack and apply it to an email I've been working on.

It sort of works, but for some reason the bars that are supposed to appear as the buger icon inside the box do not when making the browser smaller.

I've pretty much copied and pasted from the original, but can't seem to figure out why the bars don't appear. Any help in figuring out why this is happening and a fix would be appreciated. Thanks. Here is link for email.

Sorry, we seem to be having some server issues it should work now but try this one if the first link still doesn't work.
