To delay the initial loading of iframes in your Webflow site and improve the site's speed, you can use some techniques. By postponing the loading of iframes until they are needed or until after the initial content has loaded, you can optimize the performance of your site. Here are some methods you can use:

  1. Use a lazy-loading script: Implementing a lazy-loading script for your iframes allows you to delay their loading until they are in the user's viewport. This technique helps reduce the initial load time and speeds up the performance of your site. Several scripts are available that can be easily integrated into your Webflow site, such as lazysizes or lozad.js.

  2. Use JavaScript: Another approach is to use JavaScript to dynamically load the iframes after the initial content has finished loading. You can achieve this by listening for the DOMContentLoaded event and then programmatically inserting the iframes into the page. By doing this, you ensure that the main content is prioritized before loading the iframes.

  3. Implement custom interactions: Utilize Webflow's interactions feature to create custom triggers for loading iframes. For example, you can defer the loading of an iframe until a specific action, such as clicking a button or scrolling to a certain section. This way, the iframes will only load when necessary, improving the overall performance of your site.

  4. Optimize iframe content: If possible, optimize the content within the iframes to reduce their size and loading time. This could involve optimizing images, minifying JavaScript and CSS, and compressing any media files. By reducing the overall file size within the iframes, you can enhance the loading speed of the content.

Remember to test your site's performance after implementing any changes to ensure that the delay in loading the iframes does not negatively impact the user experience.
