Limitations on adding custom code

Before learning how to add custom codes in Webflow, it is important to review some basic rules.

Keep in mind that custom codes are advanced modifications. As such, they can cause conflicts with Webflow functionality, leading to unexpected behavior on your site. Therefore, there is no guarantee that each Custom Code will be fully compatible or functional.

In general, Webflow supports the following types of code:

Adding custom JavaScript codes can add a lot of functionality to your website. For this reason, Webflow also comes with a simpler version of JavaScript called jQuery. You can use it with JavaScript to make the writing process easier.

When importing jQuery, it is essential to pay attention to its version. The version should match the currently imported Webflow version to avoid conflicts and unexpected behavior. Additionally, scripts like onClick and onHover that affect DOM events can also cause unexpected behavior on your site.

When embedding custom code, you may not use any server-side languages, including:

Another critical aspect to consider is the length of the custom code. Webflow imposes the following character limitations:

  • 10,000 characters for embedded elements
  • 10,000 characters for codes on a single page
  • 20,000 characters for codes throughout the website

If the code you want to embed exceeds these character limits, you cannot embed it directly. However, you can store the code on another server and then reference the script in your code. You can also use a third-party tool to minify your custom code.

Most custom code does not affect elements in designer mode to avoid unexpected behavior. Therefore, you will only see results after your website is published.

Unfortunately, if your custom code doesn’t work, the Webflow support team won’t be much help, as custom coding is outside the scope of their customer support policy. Try double-checking your code and visit the Webflow forum for additional help, if needed.
