Is there a way of excluding the header (image, menubars etc) from individual pages? I know in the theme options I can choose which pages to display sidebars on, but I'm wondering if there is a way of having a fairly plain page, with no sidebars and none of the headers.

Thanks

If you want to prevent the header area from displaying on a certian PAGE you can use a CSS Insert

body.page-id-xxxx #header {display:none;}

where the xxxx is the page ID of your page.

For a category page you could use

body.category-xxxx #header {display:none;}

is the name of the category

Perfect. Thanks Juggledad.
