Having difficulty center-aligning the fields in a simple login page sample. The h:commandButton is aligned to center, but the other fields remain unchanged with the <div align="center">.
How can I ensure that all fields are centered?
<div align="center">
<h:message for="btnSubmit"/>
<div class='form-row'>
<div class='col-xs-2 form-group required'>
<label class='control-label'> User Name </label>
<h:inputText styleClass="form-control" size="12" maxlength="20"
id="userName" value="#{loginController.userName}"
required="true"/>
</div>
</div>
<div class='form-row'>
<div class='col-xs-2 form-group card required'>
<label class='control-label'>Password</label>
<h:inputText styleClass="form-control" size="12" maxlength="20"
id="password" value="#{loginController.password}"
required="true" />
</div>
</div>
<div class='form-row'>
div class='col-md-12 form-group'>
<h:commandButton styleClass="btn btn-success"
value="#{bundle['label.Login']}" id="btnSubmit"
action="#{loginController.clientLoginAction}"/>
</div>
</div>
</div>
