I want to modify the CSS for new tab page. NOT make new tab page. I already made a new tab page, but many users installing my themes won't also install the new tab page extension. So I want to modify the CSS on the new tab page for those who ONLY want my theme. It is my understanding that chrome://theme/css/newtab.css is the stylesheet I need to change. Feel free to tell other ways to add CSS to the ORIGINAL new tab page in Chrome.
