More Class and Id CSS Functions on every Div Thread

Hi, I'm currently editing my Moddb profile page here Moddb.com

I'm planning to make it a standard 960 width but I wanted to retain some elements on the side bar and its hard to make CSS that only have one code fits all.

I have a suggestion that would benefit most who make CSS Codes for their pages, and that would be adding dummy or more class and id for every div or element.

For example, profile uses a normalbox class and same as style, twitter, etc...

It would be good to have different or unique class for each just have a special class code as dummy tag we can edit. Also in its sub elements. Imagine that for example turning off other div items that mostly cluttering the page or make the specific social media icons ul/li float to a certain page area or in the header.
