Trying to style inside a 17Hats iFrame in WordPress
As a WordPress developer, you may have come across the need to style or manipulate content within an iframe that is hosted on a different domain, such as the 17Hats platform. Unfortunately, this is no longer possible due to cross-origin security restrictions implemented by modern web browsers.
In this article, we'll explore the reasons why you can't style or manipulate content inside an iframe from a different domain, and provide some alternative solutions to achieve your desired functionality.
The Problem: Cross-Origin Restrictions
The main issue you're facing is the same-origin policy, a security concept implemented by web browsers to prevent a document or script loaded from one origin from accessing or manipulating content from a different origin.
An origin is defined by the combination of the scheme (e.g., http
or https
), the domain (e.g., example.com
), and the port (e.g., 80
or 443
) of a URL.
When you try to access or manipulate the content of an iframe that is hosted on a different domain, the browser will block this request due to the same-origin policy. This is a security measure to prevent cross-site scripting (XSS) attacks, where malicious scripts could be injected into the iframe and potentially gain access to sensitive information or perform unwanted actions.
For example, if you have a WordPress site hosted on https://your-website.com
and you try to manipulate the content of an iframe with a source of https://17hats.com/iframe/
, the browser will block this request and throw an error similar to:
Blocked a frame with origin "https://17hats.com" from accessing a cross-origin frame.
The Solution: Workarounds
Since you can't directly manipulate the content of an iframe from a different domain, you'll need to explore alternative solutions to achieve your desired functionality. Here are a few options you can consider:
1. Use Postmessage API
The Postmessage API is a way to securely communicate between an iframe and its parent window, even if they are hosted on different domains. This approach allows you to send messages back and forth between the iframe and your WordPress site, enabling you to perform certain actions or exchange data.
Here's a basic example of how you can use the Postmessage API to communicate with an iframe:
// In your WordPress site
window.addEventListener('message', function(event) {
// Check the origin of the message to ensure it's from the trusted source
if (event.origin === 'https://17hats.com') {
// Process the message received from the iframe
console.log('Message from iframe:', event.data);
}
});
// In the iframe
window.parent.postMessage('Hello from iframe', 'https://your-website.com');
By using the Postmessage API, you can send commands or data to the iframe and receive responses back, allowing you to update the content or behavior of the iframe without directly manipulating its DOM.
2. Use a Proxy Server
Another approach is to use a proxy server to bridge the communication between your WordPress site and the 17Hats iframe. The proxy server would act as an intermediary, forwarding requests and responses between the two domains, effectively bypassing the same-origin policy restrictions.
This solution can be more complex to implement, as it requires setting up and maintaining a proxy server. However, it can be a viable option if you need more advanced functionality or control over the communication between your site and the 17Hats iframe.
3. Utilize 17Hats Integrations
If the 17Hats platform offers official integrations or APIs, you could explore using those to achieve your desired functionality. This may involve setting up a connection between your WordPress site and 17Hats, allowing you to access and manipulate data or settings without directly interacting with the iframe.
The specific integration options available will depend on the features and capabilities provided by 17Hats. You should check their documentation or reach out to their support team to understand the integration possibilities.

Conclusion
In summary, due to cross-origin security restrictions, you can no longer directly manipulate the content of an iframe that is hosted on a different domain, such as the 17Hats platform, from your WordPress site. However, there are alternative solutions you can explore, such as using the Postmessage API, setting up a proxy server, or leveraging 17Hats' official integrations.
By understanding the limitations and exploring these workarounds, you can find a way to achieve your desired functionality and integrate the 17Hats platform seamlessly with your WordPress site.
