title: Flat buttons vs raised buttons
body: <p>I want to know the basic difference between <code>Flat button</code> and <code>Raised Button</code>. According to the new <code>Android</code> material design guidelines i want to use raised button but i don't know what are they. there are forums on the web that display a button which is raised but they call it Flat. </p>
  
  <p>can any one tell me the base difference between the two ? (By Look specifically)</p>
