rx-search.css

I’ll build this as a production-ready rx-search.css file for your RX Theme: global variables, search form UI, live results, archive/search page layouts, filters, pagination, dark mode, responsive design, accessibility, RTL, and print support.

Friend, below is a strong advanced-level assets/css/rx-search.css for your RX Theme. It is written safely with the prefix rx- so it will not easily conflict with WordPress, plugins, or future app/chunk CSS.

Use this file here:

rx-theme/assets/css/rx-search.css

Then enqueue it from your theme, for example inside your enqueue file:

wp_enqueue_style(
    'rx-search',
    get_template_directory_uri() . '/assets/css/rx-search.css',
    array(),
    wp_get_theme()->get('Version')
);

Best naming system for this file:

assets/css/rx-search.css

Best related future files:

assets/js/rx-search.js
template-parts/search/search-form.php
template-parts/search/search-results.php
template-parts/search/search-empty.php
template-parts/search/search-filters.php
search.php
searchform.php

This CSS is safe for an advanced WordPress theme because it uses rx-search- scoped class names, CSS variables, responsive layout, dark mode, RTL, accessibility, live-search dropdown styling, mobile overlay, and search archive result design.
