Custom codes

The Custom codes section lets you inject CSS or JavaScript across your site, in order to tweak its appearance or plug in a third-party script that the standard marketing plugins don't cover. This is an advanced feature that requires basic development skills.

Come here when you need to add CSS that the themes don't cover, when you want to integrate a third-party script (chat widget, A/B testing tool, specific advertising pixel…), or when you want to temporarily disable an existing code without deleting it.

Custom codes

This section lists every custom code already added to your site, with its Name, its Type (CSS style or JavaScript) along with its location (head or body), the Last edited date and its Status (Visible or Inactive). Click on a row to open the code and edit it; the Enable / Disable switch at the top of the form turns the code off without deleting it. When you select several rows, the More actions menu lets you activate, deactivate, delete or export them to a CSV file.

To add a new code, click Create a code. Choose the Code type (CSS style or JavaScript) and its Code location (head or body tag), name your code so you can find it later (the description is optional), then paste its content into the editor. Save to apply the code to your site immediately.

Caution

An error in an injected code can break your site's display or block its operation (blank page, scripts crashing, broken forms). Test your code before saving, and disable it immediately if a malfunction appears live, rather than trying to fix it under pressure.

Not a developer?

This section assumes minimum HTML, CSS and JavaScript skills. If you want to add a third-party script (chat, pixel, analytics) without coding, first check Marketing extensions: the most common services already have a dedicated field there. For a specific case not listed, you can open a Support request: we can help you set it up.
