[EventCalendar] Display in posts: get rid of red box?

[webmaster at vabike.org]

Hi everyone,

I've been pretty happy with Event Calendar but I don't like how it  
displays in posts.  I'd like to get rid of the red box, and instead  
just have a line of red text inside its own <p> tags.  How can I  
accomplish this?

Thanks,
