custom CSS

Custom CSS & JS by ClassyDevs is a free PrestaShop module that lets store owners and developers inject custom CSS styles and JavaScript code into their storefront directly from the admin dashboard. Rather than editing theme files over FTP or modifying server-side code, this module provides two text areas in the back office — one for CSS and one for JavaScript — where changes can be entered, enabled, or disabled at any time without touching core files.

• Add custom CSS and JavaScript from the admin back office — no FTP access required
• Independent enable/disable toggles for the CSS and JavaScript fields
• Theme-specific CSS and JavaScript conditions supported
• Extremely lightweight with no third-party library dependencies
• Stores CSS and JavaScript in variables rather than writing directly to files

This module suits store owners who need to make quick visual or behavioral tweaks to their theme without developer assistance, as well as developers who want a convenient injection point for style overrides and small scripts without modifying theme files directly.
