_brv_

I don’t want to change the font size as per h3 tag. I want the title to be a h3 tag.
I found a solution modifying the files functions.php and footer.php.
BUT I’m not sure that these are done in a proper way. Here what I have right now:
in functions.php:

function brv_widgets_init() {
        unregister_sidebar('footer-widget-area');
        register_sidebar( array(
                        'name' => __( 'Footer Widget Area', 'brv' ),
                        'id' => 'footer-widget-area',
                        'description' => __( 'footer widget area', 'brv' ),
                        'before_widget' => '<div class="col-md-3 col-sm-6 enigma_footer_widget_column">',
                        'after_widget' => '</div>',
                        'before_title' => '<div class="enigma_footer_widget_title"><h3>',
                        'after_title' => '</h3><div class="enigma-footer-separator"></div></div>'
                ) );
        dynamic_sidebar( 'footer-widget-area' );
}

remove_action( 'widgets_init', 'weblizar_widgets_init' );
add_action( 'widgets_init', 'brv_widgets_init' );

and in footer.php with call to brv_widgets_init();:

<!-- enigma Callout Section -->
<?php $wl_theme_options = weblizar_get_options(); ?>
<!-- Footer Widget Secton -->
<div class="enigma_footer_widget_area">
        <div class="container">
                <div class="row">
                        <?php
                        if (  is_active_sidebar( 'footer-widget-area' ) ){
                                //dynamic_sidebar( 'footer-widget-area' );
                                brv_widgets_init();
                        } else
                        {
                        $args = array(
                        'before_widget' => '<div class="col-md-3 col-sm-6 enigma_footer_widget_column">',
                        'after_widget'  => '</div>',
                        'before_title'  => '<div class="enigma_footer_widget_title"><h3>', // added <h3> BRV 01/12/2015
                        'after_title'   => '</h3><div class="enigma-footer-separator"></div></div>' ); // added </h3> BRV 01/12/2015
                        the_widget('WP_Widget_Pages', null, $args);
                        } ?>
                </div>
        </div>
</div>

is it OK this way of doing things? It’s not clear for me the sequence order when the page is loading…
