rx-admin.css

harun.bspt2014@gmail.com

I’ll build this as a strong rx-admin.css foundation for RX Theme admin UI: variables, layout, cards, forms, notices, tables, tabs, badges, dark-mode-ready support, responsive behavior, and WordPress admin compatibility.

Friend, place this code in:

assets/static/static-css/rx-admin.css

This is an advanced admin CSS foundation for RX Theme. It is safe for WordPress admin pages and designed for your RX Theme settings panel, cards, forms, buttons, tabs, tables, notices, status badges, responsive layout, and future plugin/theme options.

For WordPress admin loading, enqueue it like this inside your admin enqueue file, for example:

function rx_theme_admin_assets( $hook ) {
    wp_enqueue_style(
        'rx-admin',
        get_template_directory_uri() . '/assets/static/static-css/rx-admin.css',
        array(),
        wp_get_theme()->get( 'Version' ),
        'all'
    );
}
add_action( 'admin_enqueue_scripts', 'rx_theme_admin_assets' );

Best naming is:

Handle: rx-admin
File: rx-admin.css
Purpose: RX Theme admin dashboard/settings UI
