twenty ten single column

that single-column file is a page template; when you add a new page (in admin), there is a box on the right: ‘attributes’ ‘template’-dropdown field.
select the page template for your page there.

remove this function <?php get_sidebar(); ?> from index.php, single.php, page.php etc files

I think that according to my knowledge @puglet. 🙂

do you need to upgrade the CSS to use this code? if not where are the index,single or page php files? I don’t see them.
Thanks
