title: How to get an animated underline effect in HTML?
body: <p>I am designing my personal website for the very first time using Bootstrap. I think it would be an amazing learning experience. I have used Jekyll in the past but I ended up learning very little out of that.</p>
  
  <p>For my website, I'd like to use the <strong>animated underline</strong> seen at <a href="http://tobiasahlin.com/spinkit/" rel="nofollow">http://tobiasahlin.com/spinkit/</a> when you hover over 'Source' or 'View on Github'. I tried looking for it at places but could not find it as I'm not sure if I am searching for the right things.</p>
  
  <p>I would appreciate it if someone showed me a way to write this. I am assuming CSS would be used for such an effect.</p>
  
  <p>Thank you.</p>
