I am using Reference 1.6 theme by Super Site here:
When I do a css validate using the W3C validator I get 14 errors. Most of these are telling me that I am using css level 2.1 and the properties in the theme are for level 3. I love the theme but it is not regularly updated. I thought maybe a plugin was causing this, but I just installed a new WordPress on a test site, and loaded this theme before adding any plugins but I get the same error.
I know how to edit style sheets to change various elements, but I'm lost on how to fix this one. Do I need to upgrade to css3, and if so how? If not, what do I change to get it to validate in the css I have?
