Challenge: Add Font Awesome Icons to our Buttons

Link to the challenge:

Hello @Advitya-sharma,

<span> is an HTML semantic tag that acts like… a span on the page. In this exercise, you are using Font Awesome icons, and they use the <i> tag for the tag to put icons on. But sometimes, you can also use <span> as your tag instead of <i>, it doesn’t matter, the CDN will still use that span. That’s what the exercise is trying to say, just a healthy reminder and tip…
