Just as its name implies, Fluidity is a fluid design, created to take up the full width of the screen. It is a darker theme with black, orange, and green set as the primary colours, it does hold a lot of potential.
Fluidity is a versatile and a very powerful theme and has a fluid layout. I have created three version of the same theme namely with left sidebar , right sidebar and 3 column theme.
The theme was originally developed by Dave.I ported and modified it for WordPress.
