rx-forms.css

harun.bspt2014@gmail.com

I’ll build this as a production-ready rx-forms.css for RX Theme: global form variables, inputs, labels, validation states, search/comment/contact forms, accessibility, dark mode, responsive rules, and WordPress-specific form styling.

Dear friend, paste this full code into:

assets/css/rx-forms.css

This is an advanced, performance-friendly form CSS file for RX Theme.

/*!
 * RX Theme Forms
 * File: assets/css/rx-forms.css
 * Purpose: Advanced form styling for WordPress forms, search forms, comment forms,
 * contact forms, newsletter forms, login forms, WooCommerce-style forms, and utility states.
 * Author: RX Theme
