Enabling the Custom Code Snippets Extension is simple. Go to the Blocksy Dashboard -> Extensions -> Pro Extensions -> Custom Code Snippets.
To add a Global Code Snippet, simply navigate to the Customiser -> Extension -> Custom Code Snippets section. Everything you add here is executed throughout the whole website. It’s useful in case you wish to add things such as Google Tag Manager.
Per Page/Post Snippets
You can also add snippets just on that special part of your website, like a page or a post. For example, you could add Facebook Pixel Tracking on the “Thank You” page at the end of a transaction.
Simply edit the page or post with Gutenberg, click on the Blocksy settings in the top right corner of the screen and choose Custom Code Snippets.
