Vertically align span in a div

Question

I am trying to vertically align the content "ABC Company" in a div using Bootstrap 4's alignment helper classes; but unable to do so. I am using the below code.

<div class="container" style="width: 740px;">
<div class="row">
  <div class="col-sm text-right" style="line-height: 20px; height: 20px; color:#004990; text-decoration:none; font-family:Helvetica, Arial, sans-serif; font-size:10px;">
      Your Account
  </div>
</div>
<div class="row">
  <div class="col-sm text-center" style="background-color:#0471AF; height:100px;">
    <span class="align-middle">ABC Company</span>
  </div>
</div>

Please point out what am I missing !

Solution

Set display: flex; justify-content: center; align-items: center; for col-sm text-center or, alternatively, set display: flex; justify-content: center; for col-sm text-center and align-self: center; for <span>.

.col-sm.text-center {
    display: flex;
    justify-content: center;
    align-items: center;
}

<link href="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0-alpha.6/css/bootstrap.min.css" rel="stylesheet"/>
<div class="container-fluid">
<style>

</style>
<div class="row">
  <div class="col-sm text-right" style="line-height: 20px; height: 20px; color:#004990; text-decoration:none; font-family:Helvetica, Arial, sans-serif; font-size:10px;">
      Your Account
  </div>
</div>
<div class="row">
  <div class="col-sm text-center" style="background-color:#0471AF; height:100px;">
    <span class="align-middle">ABC Company</span>
  </div>
</div>

if you are planning to have an image... use an image. It is much easier. Then play with padding-top, padding-bottom, margin-top, margin-bottom.
