Overview

This Tutorial describes how Plone chooses a skin when you open a web page, and then describes the multiple ways that you can intervene to switch (a) the skin proper, i.e. the skin layers that are used; (b) the CSS and javascript resources that are used.

More specifically, the Tutorial discusses:

• Using standard TTW forms to change underlying settings in a portal that determine what skins are displayed;
• Using one-time Python scripts that change these underlying settings;
  
• Using Access Rules that switch the skin every time a web page is loaded.
  

The Tutorial also discusses two common use cases, switching skins based on URL and the type of user (e.g., Anonymous or Authenticated), giving references for the first use case and sample code for the second.
