Horizontal output

Greetings,

I was wondering what is the correct css code in order to make the output horizontal instead of being vertical?

Also I am trying to find how can i change the Title bar header. On my site streetstyleradio.com I would like to have the Network Latest Post in the main content widget area but when I do put it there it doesn’t have a title header like the others in my theme.

Thanks
