AppRanks verdict
Generated from live marketplace data — refreshed daily
Custom CSS and JS is a newly-listed WordPress app with a limited review volume. It is listed in the Post category on WordPress Plugin Directory, which AppRanks treats as the canonical taxonomy node for ranking and competitor comparison. no published reviews yet means feature claims are unverified by the wider merchant base. Without a published review base, the only fit-signal available is the developer's own documentation plus the marketplace's listing-quality audit (linked below). Paid-only pricing means evaluating fit on the marketplace listing or via the developer's documentation before installing. AppRanks tracks rating, review count, pricing tier, and category position daily — the figures on this page reflect the most recent scrape from the canonical WordPress Plugin Directory listing.
Pros
- No standout positives based on current data signals.
Cons
- −No public reviews yet — fit and reliability are unverified

How Custom CSS and JS works
Show full descriptionShow less
Custom CSS and JS allows you to add stylesheets and JavaScripts to any individual post by adding custom fields. Both CSS and scripts can be either internal or external. Since this is a plugin, the custom CSS and JavaScript are available to any theme used to display the post, as long as the themes call “wp_head”.
Using the Plugin To use the plugin, add any combination of the following custom fields to your post.
custom_css
Add an external stylesheet by adding a custom field with the name custom_css. The value of the field should be the path to your css file.
cusrom_css_code
Add an internal stylesheet by adding a custom field with the name custom_css_code. Include your CSS code as the value. (Do not include the style tags.)
custom_js
Add an external JavaScript by adding a custom field with the name custom_js. The value of the field should be the path to your script.
custom_js_code
Add an internal JavaScript by adding a custom field with the name custom_js_code. Include your JavaScript code as the value. (Do not include the script tags.)
Custom Fields Order
The external styles and scripts are included before the internal ones.
If you include multiple entries for a given field, the entries will be included in order.
Okay, but what if I don’t like those tags? Just edit custom-css-js.php and change the constants defined near the top of the file.
Note This plugin only works with individual posts and pages. It does not work for list pages (e.g., the index page, search results).
