Answer 1

In Bootstrap 4, the vertical alignment issue is no longer a problem since the badge will inherit the size of the containing heading..

<div class="container">
  <h1><span class="badge badge-pill badge-dark">badge</span> Heading 1</h1>
  <hr>
  <h2><span class="badge badge-pill badge-dark">badge</span> Heading 2</h2>
  <hr>
  <h3><span class="badge badge-pill badge-dark">badge</span> Heading 3</h3>
</div>

However, the align-middle class be used to vertically align badges outside of the heading.

<div class="container">
  <span class="badge badge-pill badge-dark align-middle">badge</span> <span class="h1 align-middle">Heading 1</span>
  <hr>
  <span class="badge badge-pill badge-dark align-middle">badge</span> <span class="h2 align-middle">Heading 2</span>
  <hr>
  <span class="badge badge-pill badge-dark align-middle">badge</span> <span class="h3 align-middle">Heading 3</span>
</div>

Always hated this problem.

A little hacky but this works:

h1 { font-size: 2em; }
h2 { font-size: 1.6em; }
h3 { font-size: 1.4em; }
h1,h2,h3 {
    vertical-align:middle;
}

  h1>.badge, h2>.badge, h3>.badge {
    vertical-align:middle;
    margin-top: -0.5em;
}
