Nature of themes

Themes are neither solid, liquid or gas. They are collection of PHP scripts, HTML/CSS files and images, living under themes folder at root with folder name same as theme name. For Example: Theme Demo will be at ROOT/themes/demo. Theme files are interlinked and hooked together to form the actual website.

Why develop themes?

These are the reasons why should you learn theme development of Social Network Software.

• Complete control over layout, presentation and various design elements.
• Tweaking already existing themes according to your and your community taste.
• When your requirements are too unique and specific to be found in our theme gallery.
• Migrating from a non-Social-Network-Software powered website to a Social-Network-Software powered one.
• You wish to frame out of box ideas inside Social Network Software.

Theme Structure

For a minimal theme you will require two files:

• text.htm - Which is responsible for basic layout of the homepage. It determines where elements like banner, menu, footer and other elements of homepage will be placed and arranged which in turns makes clear structural layout of homepage.
• main_home.php - This file paints what will reside inside other elements of homepage like login form, signup form, welcome text and featured content.

So the homepage is rendered at two levels.

First level structure

Which is controlled by text.htm which looks like an HTML file with placeholders in special format.

Our basic website structure is clear here.
