Just waiting for this demo app to load...

Hi

There should be three components here. One red, one green, one blue:

I'm a red component I'm a green component I'm a blue component
I'm a content span
I'm just a div with the .red class
I'm just a div with the .green class
I'm just a div with the .blue class

Nesting

I'm a blue component. I'm a red component. I'm a green component.
