New theme HTML5 Support for Search in WordPress 4.4

Question

You can add HTML5 support which will be very useful. I will consider that you won’t be testing your new wordpress theme on all the real devices due to which you should add HTML5 support in functions.php. You can frame the code as below:

function customTheme_setup() {
    // HTML support
    add_theme_support( 'html5', array( 'search-form' ) );
    // Thumbnails support
    add_theme_support('post-thumbnails');
}
add_action('after_setup_theme', 'customTheme_setup');

Please let me know, if you have any query.
