Can anyone tell me what "parts" and style sheet WP uses to create a single post/comments page? That's where I'm stuck now, my styles are being ignored or overridden and I can't figure out why. I see in the single post page <body class="single single-post postid-1 single-format-standard"> so the page does not center like the rest of the site.
Also if I could just know where to assign a new class for entry, post, etc. I can get the text confined to a smaller area so the right column shows the widgets.
Sorry if I sound like an idiot, but I'm toast after struggling with this for 2 days. Time to retire, I can't keep up any more.
