make a post full width
all single posts, or just one single post?
possibly, in single.php remove the call of the sidebar(s); ususally <?php get_sidebar(); ?>
then adapt the css to stretch the content over the full width.
there is no general solution – these will be theme specific.
Just for single posts. About every 10th post should be full width.
The majority of posts shall retain sidebar(s).
About every 10th post should be full width.
how do you want to define this?
randomly?
per custom field?
the pinciple remains the same, only that you might need to wrap the sidebar call into a conditional statement to make the change randomly or checking the custom field content.
