title: How to definitively align vertically and centrally with the bootstrap?
body: <p>I tried a lot before creating this doubt, but I didn't find anything like that, I can't align a div vertically with the bootstrap, how can I do this?</p>
  
  <p><div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">
  <div class="snippet-code">
  <pre class="snippet-code-html lang-html prettyprint-override"><code>&lt;link href="https://stackpath.bootstrapcdn.com/font-awesome/4.7.0/css/font-awesome.min.css" rel="stylesheet" /&gt;
  &lt;link href="https://stackpath.bootstrapcdn.com/bootstrap/4.3.1/css/bootstrap.min.css" rel="stylesheet" /&gt;
  
  &lt;div class="container text-center p-5"&gt;
    &lt;h1 style="font-family: 'Montez', cursive; font-size: 100px;"&gt;Nome&lt;/h1&gt;
    &lt;p style="font-family: 'Montserrat'; font-size: 20px;"&gt;Dev&lt;/p&gt;
    &lt;a href="#" class="btn btn-primary col-lg-4 col-sm-4 col-md-4 rounded-pill font-weight-bold"&gt;PORTFÓLIO&lt;/a&gt;
    &lt;div class="mt-4"&gt;
      &lt;a href="#"&gt;
        &lt;i class="fa fa-instagram fa-2x"&gt;&lt;/i&gt;
      &lt;/a&gt;
      &lt;a href="#"&gt;
        &lt;i class="fa fa-linkedin fa-2x"&gt;&lt;/i&gt;
      &lt;/a&gt;
    &lt;/div&gt;
  &lt;/div&gt;</code></pre>
  </div>
  </div>
