How to make your plugin responsive?

Hi, and thanks for a great wp plugin!

I was just wondering if it is possible to make your like box responsive? I am running a responsive theme om my site hence it would be great if i could make the like box responsive as well. I am not that good with coding so therefore it would be awesome if you could explain to me how to do it.

Many thanks!

Jakob
