title: Double underline under h1 in CSS
body: <p>I want to have my h1 have two borders under it. One that is thick and just the width of the text, and a second that is thinner and the width of the entire container. </p>
  
  <p>Like this: </p>

  <p>How can I do this with CSS? </p>
  
  <p>I've tried quite a few things, and it seems like it'd be easy, but I can't figure it out! I also can't find any other forums or posts like this. </p>
