How can I embed a webpage using "iframe src" in Webflow if nothing is showing up?

TL;DR
  • Verify the source URL and ensure the site allows embedding; use Webflow's Embed Element with the correct <iframe> code.
  • Inspect for X-Frame-Options and Content Security Policy restrictions, and test in multiple browsers. 
  • Save, publish, and adjust settings for proper display.

If you're trying to embed a webpage using an iframe in Webflow and it's not displaying, there may be several reasons why it's not working. Here’s a step-by-step guide to address the issue.

​

1. Verify the Source URL

  • Ensure the URL is correct: Double-check the src URL you are using in the iframe to make sure it's the correct one and that it's live.
  • Check for embedding restrictions: Some websites block embedding through iframes, so confirm that the site allows being embedded.

​

2. Use the Webflow Embed Element

  • Add an Embed Element: Go to the Add panel in Webflow, and drag the Embed Element onto your page.
  • Insert the Iframe Code: Within the embed code editor, type <iframe src="[your URL]" width="100%" height="500" frameborder="0" scrolling="no"></iframe>. Replace [your URL] with your specific URL.

​

3. Inspect Browser Restrictions

  • Look for X-Frame-Options: Some sites set a header named X-Frame-Options that can prevent it from showing in an iframe.
  • Test in Another Browser: Try accessing your Webflow site in different browsers to confirm it's not browser-specific.

​

4. Security and Cross-Origin Policy

  • Check Content Security Policy (CSP): Make sure the site you’re embedding isn't restricted by CSP headers that prevent its content from being loaded in iframes.

​

5. Update and Test

  • Save and Publish Your Changes: Once the iframe parameters are set correctly in Webflow, publish the site to test if the embedded webpage shows up.
  • Test Different Settings: You might need different height or width settings to better fit the embedded content if the issue is with its display rather than embedding.

​

Summary

Embedding an iframe in Webflow requires a working and embeddable URL, using the Webflow Embed Element, and being aware of restrictions like X-Frame-Options or CSP. Make sure your settings are correct and test across different browsers once embedded.
