Having different theme elements for different pages I am trying to wrap up an HTML theme into a drupal template and I cannot get right idea on how to do this. 

I am having a front page, that is unique in it's elements. Then, I am having another page that only keeps the header from the front page, and footer. On this page, I am having some boxes, in witch the content should be nodes. How can I do this? 

After that, I am having different pages where I need to add their elements from the admin panel as content. So, there will be more categories, and I need to list the elements from each category into some pages that have different style. 

Also, there are regions like footer, where I have some logos ( images ) that again, they need to be nodes and added/edited from the admin panel as content. 

Can someone point me to the right direction? 

I have tried to create some pages from the admin panel, and tried to use files like page--.tpl.php to have a page in witch I should add nodes/content as the page elements but it is not rendering. Neither if I try lie page--node--.tpl.php or things like that.

I have searched on google for a few hours but I haven't mnaged to get the propper solution.

Thank you in advice!

Best regards,

Check out Context module - it will allow you to structure the website based on the node type, URL or other parameters. Depending on this, you can have different blocks displayed, or use different layouts.

See also Display Suite and Panels modules for even more possibilities.

If you want to avoid using additional modules, you can achieve similar functionality through code and preprocess_html or preprocess_page implementations. You can specify special templates that will be selected dynamically, e.g.:

function MYTHEME_preprocess_page(&amp;$variables) {
  // Make sure we are on the single node page.
  if (arg(0) == 'node' &amp;&amp; arg(1) &amp;&amp; !arg(2)) {
    // This will allow you to have separate page.tpl.php template used only
    // for single nodes. You should have page--single-node.tpl.php file in
    // your theme to see this in action. You can combine this with any
    // additional number of conditions, e.g. node type, user role etc.
    $variables['theme_hook_suggestions'][] = 'page__single_node';
  }
}
