Bootstrap footer doesn't stick to the bottom of the page

I'm currently working on some design and front-end issues, I'm not really a Front-End specialist of positioning and other similar elements. So for now I have built some design in my <div class="container"></div>, and basically the thing is that my footer sticks up near my last element, for now in the middle. I tried using <br> but that's not what I want... How can I set it to be in the bottom of the page? Thank you!

My code:

<footer class="page-footer font-small bg-dark pt-5">

  <!-- Footer Elements -->
  <div class="container">
    <!-- Social buttons -->
    <ul class="list-unstyled list-inline text-center">
      <li class="list-inline-item">
        <a class="btn-floating btn-fb mx-1" href="https://www.facebook.com/UAB-Interkodas-1882309422025359/">
          <img alt="fb" width="30" src="{% static '/main/svgs/facebook.svg' %}">
        </a>
      </li>
      <li class="list-inline-item">
        <a class="btn-floating btn-tw mx-1">
          <img alt="linkedin" width="30" src="{% static '/main/svgs/linkedin.svg' %}">
        </a>
      </li>
      <li class="list-inline-item">
        <a class="btn-floating btn-gplus mx-1">
          <img alt="google_plus" width="30" src="{% static '/main/svgs/google-plus.svg' %}">
        </a>
      </li>
      <li class="list-inline-item">
        <a class="btn-floating btn-li mx-1">
          <img alt="google_maps" width="30" src="{% static '/main/svgs/google-maps.svg' %}">
        </a>
      </li>
    </ul>

Don't use the fixed-bottom class in the footer and try this instead. You may need to adjust the values a bit instead of using 160px.

html {
  position: relative;
  min-height: 100%;
  padding-bottom:160px;
}
body {
  margin-bottom: 160px;
}
footer {
  position: absolute;
  bottom: 0;
  width: 100%;
  height: 160px;
}
