Rapid Custom CSS

A lightweight WordPress plugin to securely add custom CSS to your site with a native syntax-highlighting editor.

🚀 Overview

Rapid Custom CSS allows site administrators to add custom CSS rules directly from the WordPress dashboard without modifying theme files. It provides a safer, faster alternative to editing style.css and ensures your custom styles remain intact even when you switch themes.

✨ Features

• Native Code Editor: Utilizes WordPress's built-in CodeMirror library (wp_enqueue_code_editor) for syntax highlighting, bracket matching, and line numbers.
• Highly Secure: Implements strict data sanitization (wp_strip_all_tags) on both save and output (Late Escaping) to prevent XSS attacks.
• Lightweight: The editor assets only load on the specific plugin settings page, ensuring zero performance impact on your WordPress admin dashboard.
• High Priority Output: Custom styles are injected into the <head> of your website with a priority of 99, ensuring they override default theme styles.

🛡️ Security Details

This plugin was built with strict WordPress security standards in mind:
