The Blank theme by ThemeFlood has a variety of possible uses; ranging from casual addon testing through to learning web coding, building backend / utility webpages, drafting new content, and even the construction of full websites from a blank canvas.
This latest version (exclusively for RapidWeaver 8 and above) gives you checkboxes to control what libraries or frameworks you want loaded. Plus a single colour picker to change the body background and a setting to control the maximum width of the main page container. There is absolutely nothing else! So this truly is a blank framework you can use, abuse and do almost whatever you want with. No complicated stacks or pages of boring documentation to tediously work through either. Instead, this is a blank theme to dive straight into and start using 30 seconds from now.
Offered in the frameworks and libraries, you can choose to enable:
With the default settings applied, Blank has a total page size (without content) of only about 4KB. Consider that there are some supposedly blank themes for RapidWeaver that can be over 500x that size!
