css - How do you put <a> tags here on my html code so that it doesn't affect it's background-color and color or text?

Question

I wanted to put "a" tags around my "div class="button" but the thing is, when I put the "a" tags with href, the "a" tag is working, but at the same time it is replacing the background-color and color of the text with the color of Facebook. Please help me.

Here are the HTML codes:

footer {
  background-color: #000000;
  display: -ms-grid;
  display: grid;
  height: 100%;
  width: 100%;
  place-items: center;
}

footer p {
  color: #ffffff;
}

footer p .highlight {
  color: #00ffff;
}

.wrapper .button {
  display: inline-block;
  height: 50px;
  width: 50px;
  margin: 0 5px;
  overflow: hidden;
  background: #ffffff;
  border-radius: 50px;
  cursor: pointer;
  -webkit-box-shadow: 0 10px 10px rgba(0, 0, 0, 0.1);
          box-shadow: 0 10px 10px rgba(0, 0, 0, 0.1);

If you are not into design then you can use little javascript.

 <div class="button" onclick="redirectMe('https://instagram.com')">
        <div class="icon">
            <i class="fab fa-instagram"></i>
        </div>
        <span>Instagram</span>
</div>  

And in footer you can simply define the function redirectMe()

<script>function redirectMe(link){ window.location.href = "${link}"; } </script>
