CSS - syntax pointers

hey - I’m really trying to absorb CSS and make it my standard. I feel like, because the syntax is so easy to grasp, I’m getting mired in redundancy. if anyone’s feeling especially compassionate, would you take a look at this code and throw me a suggestion on where to be more concise, and help me cut out some unnecessary code? This is for a new project, the first in a 3-month contract with a new company. I’m trying to get efficient with CSS asap, so that I can use downtime to study up on new stuff for project 2 (XSLT - really cool ****!)
Thanks so much for any insight - here’s the CSS:
