I utilize mixins heavily so I can modulize all my styling and make sure it's included in areas that are appropriate. I've learned this is the only way to handle CSS without styles getting too complicated and accidentally changing something where you didn't mean to.
Example (create a mixin that has certain styles for forms and then include it in a body.wizard page) this way I keep my CSS very dry.
General coding guidelines are horizontal. I recently switched to this. I used to do vertical and indentation but it's very hard to read with big files. I've found that it's a lot easier to read horizontal CSS.

I alpha all my styles from a-z.
