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.
