How CJT can help you

CSS front-end changes

No need to modify theme files or work with tedious built-in theme options. Just create a CSS code block.

Adding site functionality

Stop adding plugins for simple tasks as they can slow down your site. Create a JavaScript or PHP code block instead.

Third-party scripts

Code blocks are perfect for adding scripts such as Google Analytics and chat widgets to your website.

Location Editor

Assign code blocks to specific WordPress locations, including the entire website, pages, posts, recent posts, blog index, categories, search pages, archives (tag, author), the website backend, and 404 errors. You can also target specific URLs or use Regex for dynamic control. With an invert feature, run your code everywhere except selected locations for flexible customization.

Additional Locations

Run custom code on WordPress post tags, embed it in pages, posts, or custom posts via shortcodes, and integrate it into widgets for sidebars or footers. Create single metabox code blocks at the post-edit level for redirects, and use Gutenberg’s shortcode embed feature for block-based customization.

“Several other plugins we tried failed to insert code correctly. Although this has a slightly ‘clunky’ interface it has so far inserted code accurately every time. Recommended.”
