I based my ideas off of the following thoughts and questions:
1. To what extent can a user modify a theme without programming?
- Currently, certain themes allow the user to select various parameters to customize the look of their website. What if users could visually edit the wireframe of their website and administer the positions of widgets and content?
2. How can users be encouraged to employ principles of graphic design in their themes?
- CSS frameworks (such as Blueprint  and YUI Grids ) allow designers to easily combine the principles of print design and web design through the use of grids. While grids are by no means necessary, they encourage a consistent website aesthetic and provide clarity when handling large amounts of content.
3. Can the memory print of a default theme be optimized after it has been customized?
- Customized themes often contain unused and overridden CSS and hidden DOM elements. Can these be automatically removed or avoided?
With these questions in mind, I have developed an outline for a WYSIWYG theme generator and editor. I’ve found that by placing a formal divide between structure and style in CSS a theme can easily be manipulated by the user. Since CSS and HTML are functionally linked, compiling structural CSS and HTML in tandem allows a theme to be built and optimized the fly. By treating stylistic CSS as a separate entity, the aesthetic look and feel of a website can be preserved across structural edits. This flexibility will allow the user unprecedented freedom and speed in theme design and customization.
Creating and embedding a grids-based system within the editor will provide a consistent foundation on which pages can be built. Making themes cross-browser compatible is tedious work and a headache for users of all experience levels. By embedding cross-browser functionality in the theme generator, all themes created by the editor will be inherently cross-browser compatible.
I’m seeking to make theme design within WordPress a natural process. I plan to refer to and learn from other attempts to build a theme editor, such as the now defunct Canvas, when I create my implementation. Ideally, the theme editor will become useful tool for users of all experience levels.
