What is Custom Code in Squarespace?
All websites are created using programming code.
This code is a combination of letters and numbers that tells the website how to act and look.
Most website content design editors, like Squarespace, are what are known as WYSIWYG, or ‘what you see is what you get.’
This is what how it looks when you edit a Squarespace site:
…and this is what you actually edit:
This means that rather than coding the website yourself, you tell the design editor how you want the site to look, and it creates the relevant code around your requirements.
Custom code lets you directly insert your own code into Squarespace, overriding the web editor with your own design choices.

Is it Safe to Add Custom Code into Squarespace?
Yes, for the most part.
One thing to bear in mind when doing this: custom code falls outside the scope of Squarespace’s support.
This means Squarespace can’t help with any custom code you want to add or support you if the code breaks your website.
Also, even if your custom code works now, there is no guarantee that it will work in the future when Squarespace update it service.
So if you do want to add custom code to your Squarespace website, be careful.
Always thoroughly test your code before adding it and ensure it has come from a trusted source.
You can also use a plugin that automatically generates and updates the code for you, like Spark Plugin.
