How to do that ?

I have tested

width:500px
margin-left: auto;
margin-right: auto;

Where the defautl settings is
margin: 0 0 30px 0;

But nothing happend.

Without the version of atahualpa and wp, the url, the name of the option you put that code in, there really isn't much anyone can do for you?

wp 3.1.1
Ata 3.6.4

I put the code in the POST Container

when you say you want to center the post container, do you mean the 'contents' of the post container or the container itself?

The post container itself.

(like the comment input field)

can you point me at a url that shows the issue? I think we're having a terminology issue and I'm not 'getting' your issue.

center the itemes on a multi post page...

Look at this picture ... this is from the center of my three-columns I use

http://www.mcdz.net/wp-content/uploads/Skarmklipp.png

I would have the posts in the middle of that column.

Mabey I should use some html to tha page I use for a mulit post page?

Ok now I see. Actually the post container IS centered in the center area. You can see this by adding

border: solid 1px red;

to ato->Style POSTS & PAGES->POST Container

What you want to do is center all the elements inside the 'post' container and the 'reply' container.

Go to ato->Style POSTS & PAGES->POST Container and add

text-align:center;

you might want to do it for 'POST Container: STICKY' too.

To cause the 'comment' area to be centered, go to ATO->Style & configure COMMENTS->Comment Form Style and add

text-align:center;

to it too

Thnx juggledad!
