Hope someone from the team can shine some light on this.
I finished my website design using RLM and MB, everything works just fine. Now for the really tough part of SEO and making google happy, as part of this endeavor I am running W3C css validator and lo and behold I got hit with 79 errors.

Seeing as the CSS is automatically generated by RLM and MB is there anything I can do to reduce or eliminate these errors to make google happy or am I just trying to go upstream without a paddle?

Because the css files are compressed, they will not validate. We also use certain hacks to make the page load on older browsers which do not validate as well.

Not to worry though, you can safely ignore any and all warnings that you may find.
