Input Group w/ Textarea
Created by: travpeck
The button does not align with the text-area anymore (in both Firefox and IE11).
This worked perfectly fine in Bootstrap 4 Beta:
<div class="input-group">
<span class="input-group-addon">Id</span>
<textarea class="form-control" maxlength="1000">Text</textarea>
<span class="input-group-btn">
<button class="btn btn-danger" type="button">Delete</button>
</span>
</div>
