my "like facebook button" not responsive to my web ? any recommendation ?

hi all. I wanna ask, I use responsive wordpress theme. and i used plugin “like facebook button ” to my web. but I wonder, why the plug-in doesn’t response when browser had minimized ? … is there a facebook plugin button that’s recommended for a responsive theme? or what coding should I put so that the plugin can responsive to the size of the browser and doesn’t make it bumping the web content.

here is my web post :
