title: How do I make the label appear inside the input field?
body: <p>looking at this site: <a href="http://www.gofundme.com/sign-up/" rel="nofollow">http://www.gofundme.com/sign-up/</a> they have a nice 'amount' input where you can change the $ £ € symbol. I've had it explained to me (thanks guys) how they go about that with javascript. Apparently it changes the label of the input.</p>
  
  <p>So my question is, how do they get their symbol (which is the fields label) inside the input field? </p>
