3-column layout, moving sections

It’s the CSS.. but you’d do yourself favours to grab this:

Ok, I sorta figured I would have to edit the CSS, now I need to know what. I like the layout, but how does it help me do what I want to do?

Well that layout will give you greater control.
That said, with Dots, you’ll need to give us a link and tell us just which sections need moving as for each section to be moved, it involves a minimum of 2 changes to the css.
It’s doable ??

OK, so now that i’ve changed my site, https://www.tacojohn.net , to the Trident layout, I want to move the categories, archives, search, calendar, other and meta sections to the right side. Basically, I want my info, the links and the google ads on the left, and everything else on the right. Now I just need to know how to edit the css to accomplish that.

Trident is different from Gemini in this sense. The rmenu currently carries no content. The reason for that is we do not know what content the end user will need to put in it. (a list, a div or what ?).
What you will need to do is to cut and paste the things you need into rmenu. Then you will need to write up the CSS accordingly. Maybe use the menu as a guide. And think of nests. What is inside what .
Really where you have the word #menu now in CSS you need to create something similar for #rmenu. HTH.

So for instance, in the index.php file, I can create <div id=”rmenu”>. I then move what I want into that div. Then I need to make a CSS entry for that div, similar to what is in the #menu? Sounds like a plan.

Ok, I got basically what I wanted, just now the calendar styling is all screwed up. It looks nothing like the original calendar. I inserted all the rmenu stuff in the CSS file, did that affect it at all?

My guess would be that you did not do a clean cut and paste. That calendar goes on for ever.

Hmm, I switched it back to the original index.php and wp-layout.css files, and the calendar still looks wrong. Any ideas?

What do you mean by wrong ?

I seem to have it fixed. One more question (and I a newbie at CSS so excuse me if this is dumb) but what do I have to edit to give the site a bluish theme? It seems the header, the background, the titles of the posts and the comments link.

There should be something around here:

If not, shout ??

Read this / Should get you started.

Looks good now. Read up on podz CSS guide but remember the menu bgs are graphics. You could make one up in say pale blue and slot it right in. Trident is designed so the menu bgs tile all the way down regardless of which col is longest

That’s a great tutorial, thanks.
