Hi There,
Let’s update your _topbar.php code as follows.
<?php
// =============================================================================
// VIEWS/GLOBAL/_TOPBAR.PHP
// -----------------------------------------------------------------------------
// Includes topbar output.
// =============================================================================
?>
<?php if ( x_get_option( 'x_topbar_display' ) == '1' ) : ?>
<div class="x-topbar">
<div class="x-topbar-inner x-container max width">
<a class="cart-contents" href="<?php echo wc_get_cart_url(); ?>" title="<?php _e( 'View your shopping cart' ); ?>"><?php echo sprintf ( _n( '%d item', '%d items', WC()->cart->get_cart_contents_count() ), WC()->cart->get_cart_contents_count() ); ?> - <?php echo WC()->cart->get_cart_total(); ?></a>
<?php if ( x_get_option( 'x_topbar_content' ) != '' ) : ?>
<p class="p-info"><?php echo x_get_option( 'x_topbar_content' ); ?></p>
<?php endif; ?>
<?php x_social_global(); ?>
</div>
</div>
<?php endif; ?>
Then add the following CSS rules into your Customizer, Custom > Edit Global CSS area.
.cart-contents {
border: 0.25em solid black;
padding: 5px;
border-radius: 5px;
}
Hope that helps.
