CSS & JavaScript Toolbox PLUS

PREMIUM Editor Tools

  • Full-width and full-screen mode for distraction-free coding.
  • Beautify your code to make it perfectly formatted for code readability.
  • Minify your code by removing white space for code optimisation and faster website performance.
  • Use the built-in Code Auto Completion (CAC) feature that allows you to add code into the editor automatically. The CAC utilises a code syntax dictionary so you can quickly auto-complete CSS, JavaScript, PHP, and HTML code syntax or embed code snippets. There are stacks of code snippets for you to choose from and it even supports your own local variables.
  • Choose from over 32 editor themes for changing the editor background colour, syntax highlighting colour, or adjust the font-size to just the way you like it.
  • There are many useful editor tools that you can use such as: undo, redo, find and replace, go to line, go to next error, and much more.

PREMIUM Location Editor

  • Assign code blocks to run on WordPress common website locations such as: entire website, all pages, all posts, recent posts, blog index, all categories, search pages, all archives, tag archives, author archives, website backend, 404 errors, and more.
  • Assign code blocks to run on specific website URLs or via Regex (Regular Expressions).
  • We include a powerful invert feature that allows you to run your code everywhere OTHER than what you selected in the location editor.

PREMIUM Additional Locations

  • Assign code blocks to run on WordPress post tags.
  • Assign code blocks to run on WordPress pages, posts or custom posts via the shortcode embed feature.
  • Assign code blocks to run on WordPress widgets. Great for adding code or textual content to your website sidebar or footer.
  • Add a single metabox code block at the page or post edit level. Great for one-off functions such as a page or post redirect.
  • For those that prefer to work with WordPress Gutenberg blocks. Simply use our Gutenberg shortcode embed feature.

PREMIUM Code Block Toolbar

  • Code block information panel showing useful details such as: code block ID and name, author, and when the block was created and last modified.
  • In the free version, you can choose to run your code in the header or footer of the page. The premium version gives you 8 extra hook locations such as: body open, before or after post content, before or after post excerpt, before or after posts list, and before post. These additional hooks can be useful for things like adding advertising banners just before blog posts.
  • Assign code blocks to run on WordPress widgets. Great for adding code or textual content to your website sidebar or footer.
  • Load code from an external URL link and the code will be copied and embedded to your code block automatically. This can be useful when adding code from GitHub, which you can do by clicking into the script and copying the link from the Raw button.
  • Don't lose your best code revision! Our code block revisions system lists all saved revisions with date/time stamp and author. This allows you to restore any previously saved version.

This plugin does exactly what I was looking for, so simple and effective. Congratulations to the authors!

Francesco Menzera

It works where others failed

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.

Simon Watson

This plugin saves me hours of time

This is my most used plugin. It's incredibly useful. It allows incredible customisation to a WordPress install.

All Pain of WordPress is Gone

The pain of any CMS is the box one is placed in. This plugin frees those of us who want a little extra (or a lot of extra) customisation. Adding custom CSS and Javascript in a WordPress site could not be easier.
