What it does

The short version.

01

Header & Footer

Inject code into the head tag, right after the body opens, or just before it closes.

02

CSS · JS · HTML

Paste any code — styles, scripts, verification tags, tracking pixels — it is injected as-is.

03

Page targeting

Serve each snippet everywhere or only on selected pages: home, product, cart, checkout...

04

Unlimited snippets

Create as many snippets as you need, enable or disable each one and order their injection.

The long version

Everything you'd want to know before you install.

A detailed look at how Header/Footer Code Injector (CSS/JS) works, why we built it the way we did, and the thinking behind the features above.

§ 01

Inject your code without touching the theme

The Header/Footer Code Injector lets you add CSS, JavaScript or HTML to your PrestaShop store without editing a single theme file. No more editing templates: everything is managed from a clean back-office interface that survives updates.

§ 02

Three precise locations

Each snippet can be injected exactly where you need it: in the head tag for styles, meta and verification tags, right after the body opens for markup containers, or just before the body closes for performance scripts. Ideal for Google Tag Manager, Google Analytics, Meta Pixel or Search Console verification.

§ 03

Page targeting and fine control

Create as many snippets as you like, enable or disable each one in a click, set their injection order and limit their delivery to specific pages: home, product page, cart, checkout... In multistore, each snippet can be global or restricted to one store.

§ 04

Built for PrestaShop 8 and 9

The module is fully compatible with PrestaShop 8 and 9, multistore and multilingual on the back-office side (French, English, Spanish, German, Italian). The code you enter is injected as-is, with no transformation or purification, for full control.
