Forum many css errors in 4.0.3?
 

I'm new to vB so I don't know a whole lot but I've checked 5 boards that I frequent which use vB 3.8.5 and all are css valid (maybe sometimes 5 errors at most) but the one I have (4.0.3) has 240 errors out of the box. Even this board which uses 4.0.4 has many, many errors. Any reason for the sudden rise in errors and will they have any affect on the display or are they mostly there for cross-browser compatibility?

-edit- Ok, I noticed that the majority of them are there because of the rounded corners which the older versions did not have. That would explain the sudden rise, I guess.
