Theming - .info file

The dot info file in your theme is the most critical file there is.  This file tells Drupal that your theme is there and informs Drupal about the basics of your theme.  The naming convention is the name of your folder dot info.  If you created a theme, and the directory is called, bluedroptheme, you will need to name your dot info file,

Theming - Structure

When creating themes, you must understand the structure for your theme.  All themes reside in the sites/all/themes/ 

Your theme will reside in a folder within the themes folder, sites/all/themes/YOURTHEME.  Within your theme directory, you will place all your css, js, images, and drupal dependent files like the .info , and template pages.

Themes can not start with a number.  You can not name your theme:  55nuns or 343GaryColemans.  It must start with a alphabetic character!


Blocks and Regions

The placement of blocks is defined by your theme, and to see the how they will display, Drupal has a nice utility.

If you are having issues visualizing your blocks and how they display on the region go to your blocks page at: admin/structure/block

Near the top of the blocks page, there is a link to demonstrate block regions (THEME).  Click that link.
