I realize that it's possible to define a static class method as private and protected in PHP. This allows for an instantiated class, or public static method to access it's own private/protected static methods. protected static function jumpOver () However I'm not sure if this is legal in the sense of OOP design. I can't find any real...

Here is an example that I do not understand: .container_12 .grid_6, .container_16 .grid_8 { width: 460px; } It seems to me that width: 460px is applied to all above mentioned classes.
