css formatting

Hi, I played up with the css to have ’em custom, but maybe I messed up something (I’m afraid to cancel the default ones and to write up some of mine, ’cause of the current results ): why the first post of the column is shown indented, and the remainder below not?
What are the css commands who rule the (more…) link’s layouting? It is currently shown very far below from the body of the headline.
