How to get all elements on a page except div's

So I'm trying to apply some css to every element on a page, but I don't want the css to apply to div's. I am currently using document.getElementsByTagName("*") to select every element, but as far as I know there isn't anyway to filter out a certain element type. I think I found some code that does what I want but It was using jQuery and I don't want to use that in this project. Anyone know how to do this?
