I am facing an issue with the design of a form. The lower edges are not aligned properly. What could be the cause of this problem?
<div class="form-group row">
<label for="inputPassword" class="col-sm-2 col-form-label col-form-label-lg">CIDR-Suffix:</label>
<div class="input-group col">
<div class="input-group-prepend">
<span class="input-group-text" id="CIDRSu123">/</span>
</div>
<input type="number" min="0" max="32" class="form-control" id="CIDRSu" aria- describedby="CIDRSu123" required>
</div>
Here is how it currently appears: https://i.sstatic.net/h9R0N.jpg
