How to hide the right and left regions from a customized login page? I'm working on Drupal 7, and trying to create one customized login page. I don't want to display the right and left regions in this page; I want a login page with only header, footer and content, where the content would be the "Username" and "Password" fields.

How can I do it?
Go to the Blocks admin page, admin/structure/block.

Find the regions you don't want to show. E.G., 'Sidebar A,' 'Sidebar B.'

'Configure' the blocks which appear in those regions. They will all have a 'Pages' tab at the bottom, and this is where you can configure which pages contain or exclude those blocks. You'd check 'All pages except those listed' and then put the path to your custom page.

HTH.
