if i'm right, you are using theme osclasswizards where bootstrap is implemented, so you can try to add a class to the outer div
change in ../telephone/index.php ~39
<div class="box control-group">
<div class="row">
<label for="telephone"><?php _e('Phone', 'telephone'); ?></label>
<div class="controls">
<input id="telephone" type="text" value="<?php echo $detail; ?>" name="telephone"></input>
</div>
</div>
</div>
to
<div class="col-xs-12 box control-group">
<div class="row">
<label for="telephone"><?php _e('Phone', 'telephone'); ?></label>
<div class="controls">
<input id="telephone" type="text" value="<?php echo $detail; ?>" name="telephone"></input>
</div>
</div>
</div>
