How can I make CSS media query gaps work on an older iPhone 5 with iOS 10.3.4 and Safari for my Ecommerce site using Webflow?

To make CSS media query gaps work on an older iPhone 5 with iOS 10.3.4 and Safari for your Ecommerce site using Webflow, there are a few things you can try:

1. Use Vendor Prefixes: Older versions of Safari may require vendor prefixes in order to recognize certain CSS properties. For example, you can try using `-webkit-column-gap` instead of just `column-gap` for column gaps in a media query targeting older iPhones.

2. Use Flexbox or Grid with Fallbacks: If you are using flexbox or grid for your layout, make sure to provide fallbacks for older Safari versions that don't support these features. You can use a combination of `display: flex` and `display: -webkit-flex` or `display: -ms-flexbox` to ensure compatibility.

3. Test with Remote Debugging: Safari's remote debugging tools allow you to inspect and debug your website running on an actual iPhone device. This can help you identify any specific issues that are affecting your media queries. You can connect your iPhone to your computer and use Safari's "Develop" menu to inspect your site on the device.

4. Test and Adjust: It's crucial to test your website on the actual device you are targeting. Use the iOS Simulator or borrow an older iPhone to ensure that your media queries are working as expected. This will help you identify any gaps or issues that need to be addressed.

5. Consider Progressive Enhancement: If you find that certain CSS properties or features are not well supported on older iPhones, you can use a technique called progressive enhancement. This involves starting with a solid baseline experience that works well on all devices and then gradually enhancing the experience for devices that support more advanced features.

6. Provide a Mobile-First Design: By adopting a mobile-first design approach, you can ensure that your website is optimized for smaller screens and older devices from the start. This will make it easier to create media queries that work well on older iPhones.

Remember, browser support for CSS properties and media queries can vary, especially on older devices and versions. It's essential to test and make adjustments accordingly to ensure a consistent and optimized experience for your users.
