Layout, Layout, Layout!!

Hi all:

I’d like to write a code that will list the events in this manner: http://sandiegoca411.com/calendar/

I wrote the HTML code but here is where it’s not working:

-Each event is being listed on a separate row, instead of four next to each other, for the same day events.

Take a look what I mean (I can only leave this up for little while longer, before anyone else sees it): http://sandiegoca411.com/events/

Can someone please provide input. Thank you!!
