PP Custom CSS & JS is a free and highly practical module for every PrestaShop administrator. It allows you to instantly add your own CSS styles and JavaScript scripts directly from the shop management panel – without logging into an FTP server and without the risk of editing theme files.

Thanks to the built-in mini-editor with syntax highlighting, managing your website's appearance and integrating external tools (such as Google Analytics, advertising pixels, or live chats) becomes simple, fast, and secure.

Key benefits for your store

  • 100% Free – a professional, premium-class tool that you receive entirely free of charge.
  • Quick fixes without a developer – change the appearance of elements or add scripts in seconds, saving time and tech support budget.
  • Work directly in the Back Office – forget about searching for FTP passwords. Configure everything in one convenient place within the administrator panel.
  • Safe for the shop engine – the module does not overwrite the PrestaShop core. Your modifications are secure and will not disappear during engine or theme updates.
  • All custom codes in one place – end the chaos of searching through `.tpl` files to find where a specific tracking script was pasted.

Main applications

This module is indispensable for everyday store management. It is ideal for quickly pasting analytical and marketing codes (Google Analytics, Meta Pixel, Hotjar), implementing seasonal visual tweaks (e.g., changing button colours for Black Friday), or hiding broken layout elements using simple CSS rules.

Features – Administrator Panel (Back Office)

1. Convenient mini code editor

Work on dedicated Custom CSS and Custom JS fields with the comfort of a proper programming editor.

  • Automatic syntax highlighting for effortless code reading.
  • Line numbering and helpful bracket auto-closing to prevent syntax errors.
  • Clean and clear text field layout.

2. Stable and secure saving

The system ensures that the code you enter is saved exactly as it was pasted, protecting it from data corruption.

  • Protection against the system stripping out essential special characters (such as curly brackets in CSS).
  • Clear, colour-coded messages informing you of a successful save or an error.

3. Updates Tab

A built-in section that ensures you always know you are using the latest, most secure version of the tool.

  • Quick preview of the module's current status.
  • Information about new features and improvements available at a glance.

Operation on the store front (Front Office)

1. Proper CSS style loading

The entered CSS code goes automatically into the <head> section. This ensures new styles load instantly when the page opens, eliminating the ugly "blinking" effect of an unstyled template.

2. Optimal JS script embedding

JavaScript scripts are securely injected at the very bottom of the page (before the </body> tag). This is a web performance best practice – ensuring scripts do not slow down the loading of your store's primary content.

3. Duplicate script protection

An intelligent internal mechanism ensures that a given script runs on the page exactly once, preventing code conflicts and reducing the load on the customer's browser.

Impact on SEO and store flexibility

The module allows you to react instantly to market demands. Need to urgently test a new review widget or fix an element alignment issue on smartphones? You can do it yourself, right away. Properly embedding JavaScript code at the bottom of the page supports optimal site loading speed, which is highly valued by Google robots for SEO rankings.

Important information

This module offers great flexibility, so please remember to only paste codes and scripts from verified, trusted sources. Before introducing major visual changes, it is always recommended to test the code in a secure staging environment or to perform a full backup.
