should cards have a fluid option?

[fuzetsu]

Right now cards seem to have a set max-width of 320px, easy enough to override with styles, but it might be nice to have a fluid option to remove that max-width.

Maybe I'm abusing cards, and should be making my own container.

I have done the same, so if you are abusing the cards, you are not alone :)

I'll add a fluid attr, it'll keep it consistent with other components.
