I've got a WordPress site I'm building, and I've got things set up so that the PHP knows not to display the sidebar on a Page, but will display it on a Post. Unfortunately, the width of the main text area is universally set up in the CSS to be right for when there's a sidebar. Is there a way to create some sort of an if/then statement that calls an alternate piece of CSS for the Page without the sidebar so my content will stretch the full width in that case?
Thanks in advance.
Please note that I am no expert in PHP. I can move things around and hopefully not break stuff, but I couldn't write a call from scratch to save my life right now.
