Spent few hours to upgrade the version of `style.css` for a wordpress theme

Finally got following, Assume you want to bump up the version of style.css for twentysixteen theme.

Go To
/wp-content/themes/twentysixteen/functions.php

[php]
function twentysixteen_scripts() {
// Add custom fonts, used in the main stylesheet.
wp_enqueue_style( ‘twentysixteen-fonts’, twentysixteen_fonts_url(), array(), null );

// Add Genericons, used in the main stylesheet.
wp_enqueue_style( ‘genericons’, get_template_directory_uri() . ‘/genericons/genericons.css’, array(), ‘3.4.2’ );

// Theme stylesheet.
//wp_enqueue_style( ‘twentysixteen-style’, get_stylesheet_uri() );
wp_enqueue_style( ‘twentysixteen-style’, get_stylesheet_uri(), array(), ‘5.4.3’ );
