so fixed it, here is what i did:
i edit the style.css , i added inside #main
.site-content2 {
float: left;
width:960px;
padding:30px 20px;
}
next i created a child template called fullwidth.php
with this code
<?php
/*
Template Name: Full Width
*/
?>
<?php
get_header(); ?>
<div id=”primary” class=”site-content2″>
<div id=”content” role=”main”>
<?php while ( have_posts() ) : the_post(); ?>
<?php get_template_part( ‘content’, ‘page’ ); ?>
<?php comments_template( ”, true ); ?>
<?php endwhile; // end of the loop. ?>
</div><!– #content –>
</div><!– #primary .site-content –>
<?php get_footer(); ?>
and it works perfect,
let me know if this is ok ?
thanks
