I think the show hide jq are what you need to use here.
Here is a link that I put together.
$("#homeButton").click(function () {
$("#cuerpo").show() ;
$("#tablet").hide() ;
});
$("#procuctsButton").click(function () {
$("#tablet").show() ;
$("#cuerpo").hide() ;
});

You could also try using iframe, you could make the buttons change the src of the frame.
