Nice theme– float:left width?

Nice theme. I was having some issues with the post titles going below instead of to the right of the date icons. After a little research it looked like specifying an appropriate width to the .posttop .title class resolved the issue (I used 510px).

I’m admittedly not the most proficient person in CSS, but after doing a little research I seemed to come to the conclusion float:left divs should always have a width specified.
