it’s not too hard
Make the new template and give it the required header like this:
<?php
/*
Template Name: Wide Content
*/
?>
I just made mine from a copy of page.php
Then remove the call to the sidebar
<?php get_sidebar(); ?>
OK, that’s the easy part. The rest you may have to stumble through. Its different for every theme
You have to create new classes/IDs and put them in your css for any parts of your page that control the narrower content and have widths on them
for instance I took <div id="content">
and changed it to <div id="wideContent">
then copied and edited the appropriate part of style.css
#content {
float: left;
width: 775px;
margin: 0px 0px 0px 5px;
padding: 0 0;
position: relative;
z-index: 1;
}
was copied and edited to this
#wideContent {
float: left;
width: 1000px;
margin: 0px 0px 0px 5px;
padding: 0 0;
position: relative;
z-index: 1;
}
and so on….
