<h3>IDEAL FOR:</h3>
<ul>
<li>Making CSS front-end changes – No need to modify theme files or work with tedious built-in theme options. Just create a CSS code block.</li>
<li>Adding site functionality – Stop adding plugins for simple tasks as they can slow down your site. Create a JavaScript or PHP code block instead.</li>
<li>Adding widgets, code snippets and third-party scripts – Code blocks are perfect for adding scripts such as Google Analytics and chat widgets to your website.</li>
</ul>
CJT is built on the concept of a code block. Each code block is more than just a code editor. It also contains a location editor so you can click the sections of your website you want your code to run.
It was designed for super-fast development without any cumbersome page refreshing. Create as many code blocks as you need and see all of your code and locations in the one dashboard. Don’t worry, CJT has been optimised to handle 100’s of code blocks and thousands of locations (i.e. Pages, Posts, Categories, Custom Posts, etc).
