I've been reading and researching how to build a responsive email - the thing is I am building it using a table. I know tables are not responsive by nature; however, I've been reading up on responsive design, media queries, and such and I still cannot find a solution. Below is what I have so far. Any help would be greatly appreciated as I would like to learn how to make an email responsive.

<style type="text/css">
@media (max-width: 480px){
 table,tbody,tr,td,img {
  display:block;
 }
 div#background {
   width: 400px;
  }
 table#container{
   width:300px;
 }
} 
</style>
</head>
