## Description

**Simple Custom Code – CSS, JS, and HTML** is a powerful yet easy-to-use plugin 
that lets you create, edit, and manage custom CSS, JavaScript, and HTML snippets—
visually or through code. Instantly apply styles to any element using an intuitive
Visual CSS Customizer, or write your own custom code snippets with full control.
All code is stored as optimized, file-based snippets for better performance, caching,
and portability — no database clutter, no complicated setup.

Whether you prefer point-and-click design or hands-on coding, the plugin adapts 
to your workflow. Use the live visual editor to experiment with fonts, colors, and
layouts in real time, or add precise styling and scripting through the built-in 
code editor with syntax highlighting and autocomplete. Both methods integrate seamlessly,
so your visual changes are automatically translated into clean, optimized code.

Designed for speed and flexibility, this plugin supports unlimited CSS, JS, and 
HTML snippets, advanced file-based management, AI-powered code generation, and a
Gravity Forms visual CSS customizer. It’s perfect for customizing your WordPress
site’s appearance, extending functionality, and keeping your changes safely organized—
without touching theme files.

### 🎨 Live Visual CSS Customizer

Create beautiful, responsive designs directly from your site’s frontend using the
built-in Visual CSS Editor. Perfect for both beginners and professionals, it combines
visual controls with real CSS generation for complete flexibility.

**Key Features:**

 * **One-Click Activation:** Launch the CSS Customizer instantly from your site’s
   admin bar.
 * **Point, Click, Style:** Select any element visually — no need to inspect HTML
   or write selectors manually.
 * **Real-Time Visual Controls:** Adjust fonts, colors, spacing, borders, transitions,
   and hover effects with instant live preview.
 * **Automatic CSS Code Generation:** Every visual change automatically produces
   clean, performance-optimized CSS.
 * **Safe Testing Environment:** Preview your changes without affecting your live
   site until you hit “Save.”

### 🌐 Gravity Forms Visual CSS Customizer

Style your Gravity Forms effortlessly with the dedicated Gravity Forms CSS live 
customizer. Accessible directly from the admin bar under **CSS Customize  Gravity
Forms**, it allows you to visually fine-tune form fields, labels, buttons, and layouts—
all in real time, with zero code required. Perfect for matching your forms to your
brand without writing a single line of CSS manually.

### ⚡ Unlimited CSS, JavaScript & HTML Snippets

Go beyond CSS. With version 1.3, you can now create and manage unlimited snippets
for CSS, JavaScript, and HTML — all from a single, unified interface. Each snippet
type is purpose-built for its use case, giving you the flexibility to style, script,
and structure your site exactly the way you want.

**Highlights:**

 * **Unlimited Snippets:** Create as many snippets as you need for CSS, JS, or HTML—
   dedicated to different themes, layouts, components, or site sections.
 * **File-Based Storage:** All snippets are saved as external files in `/wp-content/
   uploads/simple-custom-code/` for better caching, performance, and portability—
   no database clutter.
 * **Granular Control Per Snippet:**
    - Activate or deactivate snippets anytime.
    - Load externally or inline for speed optimization.
    - Choose code position (`<head>`, before `</body>`, or right after `<body>`).
    - Set priority levels to control load order.
    - Rename snippet files for better organization.

### 📍 Flexible Loading Locations

One of the most powerful aspects of the plugin is where your code gets loaded. Unlike
basic custom CSS plugins, Simple Custom Code – CSS, JS, and HTML gives you granular
control over the context and location of each snippet:

 * **Frontend:** Load CSS, JS, or HTML on the public-facing side of your site.
 * **Backend (wp-admin):** Inject code into the WordPress admin dashboard — useful
   for custom admin styles or admin-only scripts.
 * **Login Page:** Target the WordPress login screen specifically — great for branded
   login pages.
 * **Block Editor:** Load code inside the Gutenberg block editor environment for
   editor-specific tweaks.

This level of contextual control means you’re never loading unnecessary code where
it doesn’t belong, keeping your site lean and fast.

### ✍️ Advanced Code Editor with Autocomplete & Syntax Highlighting

The built-in code editor is designed for professional developers and beginners alike.
It’s not just a plain text area — it’s a smart, IDE-like editing experience inside
your WordPress admin:

 * **Syntax Highlighting:** CSS, JavaScript, and HTML are visually color-coded for
   easy reading and editing.
 * **Real-Time Autocomplete:** As you type, the editor suggests CSS properties, 
   JavaScript functions, and WordPress hooks — dramatically speeding up your workflow
   and reducing typos.
 * **Code Beautifier:** Automatically format and indent messy code with one click,
   turning unreadable code into clean, maintainable snippets.
 * **Smart Error Detection & Validation:** The editor flags syntax errors and potential
   issues in real time, before you save — so you can fix mistakes before they ever
   reach your site.

### 🤖 AI-Powered Code Generation

Not sure how to write the code you need? Simply describe what you want in plain 
English, and the AI assistant will generate ready-to-use CSS, JavaScript, or HTML
for you. Whether it’s a sticky header, a custom button style, a scroll animation,
or an admin tweak — just tell the AI what you need and it does the heavy lifting.

 * Works with CSS, JavaScript, and HTML snippets.
 * Uses your own OpenAI API key — you stay in control of your API usage and costs.
 * Generated code is inserted directly into the editor, where you can review, adjust,
   and save it as a snippet.

This feature is especially powerful for site owners and designers who want to extend
their site’s functionality without being full-time developers.

### 🔐 Smart Plugin Settings & Configuration

The Simple Custom Code – CSS, JS, and HTML plugin is built for flexibility and speed.
Whether you manage a single website or multiple client projects, its settings give
you total control over how and where your code snippets are loaded.

**Core Settings & Controls:**

 * **Role-Based Access Control:** Limit access to the code editor for specific WordPress
   roles (Administrator, Editor, etc.) — perfect for maintaining control in multi-
   user or agency environments.
 * **Cache-Busting File Versions:** Automatically append version numbers to ensure
   browsers always load the most recent changes.
 * **Performance-Optimized Output:** Choose between inline or external file loading
   to balance speed and caching efficiency.
 * **Clean, Intuitive Interface:** A lightweight admin panel that keeps configuration
   simple — no unnecessary options or clutter.
 * **Advanced Control Options:** Adjust snippet loading priority, file naming, and
   execution location directly from your settings page.

### 🚀 Upgrade to Pro – Developer-Grade Power

The free version is powerful, but the **[Pro upgrade](https://simplecustomcode.com/)**
unlocks a suite of advanced performance, automation, and precision features built
for developers, agencies, and power users who need complete control over their site’s
code delivery.

**Pro Features:**

 * **Fine-Tuned Conditional Loading:** Target your snippets to load only on specific
   URLs, post types, pages, or user conditions — not site-wide. This means faster
   pages and cleaner code delivery exactly where it’s needed.
 * **Defer JavaScript Loading:** Mark external JavaScript snippets to load with 
   the `defer` attribute, preventing render-blocking scripts from slowing down your
   page load speed.
 * **Asynchronous CSS Loading:** Load CSS files asynchronously to prevent stylesheet
   render-blocking — a key technique for improving Core Web Vitals and Lighthouse
   scores.
 * **SCSS & Less Compiler:** Write your styles using SCSS or Less syntax and let
   the plugin compile them automatically into valid CSS. No build tools or command-
   line setup required.
 * **Automatic Code Minification:** Automatically minify your CSS and JavaScript
   snippets on save. Minified versions are stored separately so you always have 
   access to the readable original.
 * **Cache Mode:** Combine all active snippets for a given page into a single cached
   file, dramatically reducing the number of HTTP requests and improving Time to
   First Byte (TTFB).
 * **Clean Source Code Output:** Remove snippet loading comments from your site’s
   HTML source code for a cleaner, more professional output.
 * **Fewer HTTP Requests:** Pro’s optimized snippet handling intelligently consolidates
   code delivery to minimize round-trips and maximize site speed.
 * **Priority Technical Support:** Get faster responses, dedicated assistance, and
   early access to new features and updates.

Pro is the ideal choice for performance-focused developers and agencies who need
production-grade code management on WordPress. **[Learn more and upgrade at simplecustomcode.com ](https://simplecustomcode.com/)**

## FAQ

### Can I use the Visual Customizer on any theme?

The customizer works on most modern, well-coded themes. It may have limited functionality
on themes that:
 – Heavily rely on JavaScript for rendering their layout – Use excessive
iframes or shadow DOM elements – Have complex, non-standard DOM structures

For best results, we recommend using it with block themes (WordPress 5.9+) or classic
themes with standard HTML structure.

### Is it safe to use on a live site?

Absolutely! You have full control:
 1. Create and test snippets while they are set
to **“Inactive”** 2. The visual customizer shows a live preview, but changes are
only saved when you explicitly click **“Save Snippet”** 3. Even after saving, snippets
won’t affect your live site until you change their status to **“Active”** 4. You
can use URL conditions to test snippets on specific pages before applying site-wide

### Can I use this alongside other CSS plugins?

Yes, but be mindful of potential conflicts. Simple Custom Code – CSS, JS, and HTML
loads after most theme styles but before other plugins. Use the **Priority** setting
to adjust load order if needed.

### I’m upgrading from a version prior to 1.3 — where did the “CSS Modifications” menu go?

In version 1.3, the **CSS Modifications** admin menu item has been renamed to **
Custom Code**. This reflects the expanded capabilities of the plugin, which now 
supports CSS, JavaScript, and HTML snippets — not just CSS. All of your existing
custom CSS snippets, settings, and configurations are fully preserved and will continue
to work exactly as before. Nothing is lost — the menu has simply been renamed to
better represent what the plugin can now do.

### Can I use the AI code generation feature?

Yes! AI-powered code generation is available in the free version. You’ll need to
provide your own OpenAI API key, which you can obtain from your OpenAI account. 
Once configured in the plugin settings, simply describe what you want in plain English
and the AI will generate the appropriate CSS, JavaScript, or HTML code for you.

### Does the plugin slow down my site?

No — performance is a core design principle. All snippets are stored as external
files (not in the database), which means they benefit from browser and server-side
caching. You can also choose between inline or external loading per snippet, and
use priority settings to ensure optimal load order. Pro users gain additional performance
tools including minification, async loading, and cache mode.

### What’s the difference between the free version and Pro?

The free version includes all the core features: unlimited CSS, JS, and HTML snippets,
the Visual CSS Customizer, file-based storage, the advanced code editor, AI-powered
generation, loading location control, and role-based access. Pro adds developer-
grade performance tools: conditional loading by URL, JS defer, async CSS, SCSS/Less
compilation, auto-minification, cache mode, and priority support.

### Will upgrading to Pro affect my existing snippets?

Not at all. Upgrading to Pro is seamless — all your snippets and settings remain
fully intact.
