What it does
Adding custom styles or scripts usually means editing theme files, and those edits can be lost when the theme changes or updates. Custom JavaScript & CSS in Pages! moves that code into the plugin, so your customizations stay in place when you switch themes. It works for styling tweaks beyond what your theme options allow, for extra interactivity, and for third-party scripts you need on certain pages. The plugin lists WooCommerce as a requirement, so it fits sites that already run a WooCommerce store.
You write code in an editor with syntax highlighting, which makes snippets easier to read and debug. Each snippet can be added inline or loaded as an external file, and placed in the header or the footer. Code can apply to the entire site or be assigned to individual posts, pages or custom post types, with visibility filters by page, post or URL. There is no cap on the number of snippets, so you can keep separate customizations organized on their own.
Best for
- WooCommerce store owners adding custom styles or scripts
- Developers placing third-party scripts on specific pages
- Designers customizing styling beyond theme options
Features
Syntax-highlighted code editor
Write and edit JavaScript and CSS in an editor with code coloring, which keeps snippets readable and makes mistakes easier to spot.
Inline or external file
Choose whether each snippet is printed inline on the page or included as an external file, depending on how you prefer to load code.
Header or footer placement
Decide whether your custom code goes into the page header or the footer, giving you control over where scripts and styles load.
Global and per-page code
Apply a snippet across the whole site, or assign it only to particular posts, pages or custom post types that need it.
Visibility filters
Set where code applies using filters by page, post or URL, so styles and scripts appear only in the places you choose.
External library support
Include outside JavaScript and CSS libraries and load them in the header or footer to bring third-party resources into your site.
Survives theme changes
Because the code lives in the plugin instead of theme files, your customizations stay intact when you switch to a different theme.
Unlimited code snippets
Add as many separate JavaScript or CSS snippets as you need, keeping each customization organized as its own entry.
