In the Backlight Docs, under CSS, it says:
When overriding default styling, it’s good to begin by examining the page template’s generated stylesheet. The best way to avoid conflicts or strange behavior is to use the same selectors that we’ve used to style Backlight.
When I look at the CSS files in Backlight (backlight/custom/css/custom.css), I don’t see much. It seems I should see more selectors. Is there another place to look?
