Simple Custom CSS and JS PRO

Changing a site's look or behavior often means editing theme or plugin files, and those edits can disappear after an update. This plugin gives you one place in the WordPress dashboard to write custom CSS, JavaScript and HTML instead. You can load the code across the whole site or limit it to specific URLs, so styles and scripts only appear where you want them.

The plugin also supports a more organized way of working. You can preview changes in a separate tab before saving, share that preview with a client or teammate, and review a versioned history of revisions. It works with Sass and Less, can minify your code, and handles multisite networks from the main installation. It suits developers, freelancers and site owners who make regular code tweaks.

Features

• Targeted code loading: Apply custom CSS or JavaScript to the entire site or restrict it to specific URLs, so each style or script loads only on the pages that need it.
• Multisite network support: Manage custom CSS, JS and HTML for every subsite from the main installation, which keeps administration in one place on a WordPress multisite network.
• Reusable shortcodes with variables: Turn any custom HTML into a shortcode that accepts variables, then reuse it across pages and posts for consistent content placement.
• Live preview before saving: Open a preview in a separate tab to see how your CSS or JS affects the site, so you or a client can approve changes first.
• Revision history with comparison: Keep a versioned log of your code changes and compare revisions to see what was added, edited or removed, which helps with troubleshooting and rollback.
• Sass and Less preprocessing: Write styles with nested rules, variables, mixins and calculations, and let the plugin process Sass or Less, including code meant for the Block editor.
• Automatic code minification: Reduce the size of your CSS and JS files through built-in minification, so custom code adds less weight to your pages.
• Export, import and admin styling: Move code snippets and settings to another WordPress installation, and add custom CSS to the admin area to adjust the backend for yourself or clients.

Best for

• WordPress developers who manage custom code for client sites
• Freelancers and agencies sharing previews for client approval
• Multisite administrators who need network-wide custom CSS and JS
