I am struggling to adjust the width of the left box to match its placeholder.
Ideally, I want it to resemble something like this:

.row {
background: #f8f9fa;
margin-top: 20px;
}
.col {
border: solid 1px #6c757d;
padding: 10px;
}

<div class="container">
<label for="phonNum"> Please enter phone Number</label>
<div class="row text-left">
<div class="form-group form-inline" show-errors>
<div class="col-xs-6">
<input type="text" class="form-control" maxlength=3 name="phoneInt" placeholder="000" ng-model="client.phoneIn">
</div>
<div class="col"></div>
<input type="text" class="form-control" maxlength=10 name="phone" placeholder="670125" ng-model="client.phone">
</div>
</div>
