Custom Category Templates on a Archive or Index page.
On my home page and in my archives, I use a custom category template to display asides and news articles. This is very easy to do and it only takes a couple seconds of work to create custom category templates in any WordPress theme. The first step is to add the following to your current theme’s index.php loop after the line that looks like <?php while (have_posts()) : the_post(); ?>, but before any other code.
