Actually I did specify a width for the content as well as both side bars. I have 600 px for content and 200 each for the sidebars. These are customizable within the theme.
The template is the default that showed up when I installled the calendar.
I haven’t looked at the code for the stylesheet though.
Not sure what the w3c validator is but if it is something in firebug I will certainly install that and see what turns up.
So which template am I running through this w3c? The event.php template?
Anyways you at least gave me more than I had so far – I know nothing about php but I will be able to piece things together eventually with enough help.
