DIV not showing up in Chrome

I just made a very simple website, but I ha开发者_JS百科ve run into a problem. In Firefox and Safari, I can see the DIV with id #sponsors, but in Chrome it is gone. I am on a mac.

Anyone have a solution?

It is set to:

visibility: hidden !important;
display: none !important;

in my Chrome and it is my Ad blocker that does it.

Change the Id to something less ad-ish.
