I have been attempting to create a 3 control input-group using Bootstrap 3.3.7, but I am encountering an issue where the height of the first addon does not match the height of the input field or button that follow.
<div class="input-group">
<span class="input-group-addon">Amount</span>
<input type="text" class="form-control" />
<div class="input-group-btn">
<button class="btn">Submit</button>
</div>
</div>
Does anyone have a solution or a sample code that successfully addresses this design problem?
