Font Awesome Icons Not Working As Links

My font awesome icons aren't linking to where I set the href on the a tag. In fact when I inspect them there is no href on the a tag. I have some demo code for you to look at, but

Solution 1:

Provide a target attribute to your a tag.

Something on the lines of:

<a target="_blank" href="https://www.google.co.uk/">
  <i class="fa fa-facebook-official fa-3x" aria-hidden="true"></i>
</a>

Check updated fiddle.

Solution 2:

Do you have the latest CDN attached to you page to display the icons?
