Ionic CSS Components. Where are the styles?

I am trying to use the Cards showcase CSS component. I copied the HTML but it appears that I also need to use the CSS to make it look exactly like shown in demo page. Where do I get this CSS, do I have to write it separately or it is available somewhere I have missed importing it?

I started with a ionic2 sample app and just copied the Markup of cards showcase to my home page.html

Hi. This is very silly, but the reason styles were not appearing were because I am using IONIC2 and I was referring to IONIC1 documentation.
