Themes

I've recently ported a rather complex Drupal 7 theme to a Backdrop layout, and wanted to talk about the experience with others. 

In this mornings session there were questions about how to customize the appearance of your site without creating a new theme.

Let's talk about things like:

• When do you need a custom theme and when can you avoid it?
• When to create a sub-theme of an existing theme.
• Ways to modify an existing theme without a subtheme.
  • CSS Injector 
  • CSS Editor
• Modules that do things that might also be done in a theme
  • Fancy Blocks
  • Configurable Block Styles
  • Sticky Menus
