Make the booking engine mobile-responsive

Why mobile adaptability is essential

Key points:

  • Over 60% of direct bookings originate from mobile devices.
  • A non-responsive search engine leads to abandoned shopping carts.
  • Mobile experience directly influences conversion and SEO.

A poorly optimized mobile booking engine negatively impacts the performance of your hotel website. Visitors struggle to read information, select dates, or complete their booking. To ensure a seamless experience, it's essential to optimize the engine's integration so that it adapts perfectly to all screen sizes, from smartphones to tablets.

Steps to make the engine responsive

1. Check the engine integration

If your engine is integrated via an iFrame, start by checking that its dimensions are not fixed.

Replace the pixel values ​​(e.g., width="600px" height="800px") with percentage values: <iframe src="https://moteur.votre-hotel.com" width="100%" height="800" style="border:0;"></iframe>

Add the following to your CSS stylesheet: iframe {

max-width: 100%;

height: auto;

}

💡 Tip: Use min-height to ensure proper readability of the content without cropping.

2. Optimize the display using the Designer

In the Webflow Designer, switch over the landscape and portrait mobile breakpoints:

  • Reduce the margins and padding around the engine.
  • Place the engine in a centered container (max-width: 100%).
  • Avoid fixed blocks or multiple columns on mobile: opt for a single, fluid column.

3. Use a responsive container (wrapper)

Encapsulate the engine in a div block configured as follows:

  • Display: Flex
  • Direction: Column
  • Align: Center
  • Width: 100%
  • Overflow: Hidden

This allows the engine size to automatically adapt to the phone's viewport.

4. Check compatibility on the supplier side

Some providers (such as D-Edge, Availpro, Siteminder or BookingButton) offer a dedicated mobile version of their search engine.

  • Enable the “Responsive” or “Mobile version” option in the engine settings.
  • If possible, test both versions (embedded vs. pop-up) to compare display smoothness.

5. Test on multiple devices

  • Open the engine on iPhone, Android, and tablet.
  • Check the input fields, the calendar, the buttons, and the payment process.
  • Use Chrome's built-in testing tools (DevTools → Responsive mode).

Best practices

  • Avoid redirects to non-responsive external search engines.
  • Maintain high contrast and easily clickable buttons.
  • Add a clear "Close" button if the engine opens in a pop-up window.
  • Check that the loading script does not block scrolling on mobile devices.

Conclusion

Making the booking engine responsive is an essential step for any high-performing hotel website. Seamless integration, dynamic dimensions, and multi-device testing guarantee an optimal user experience and a higher conversion rate.
