Overview

Wix has technical constraints that affect how embedded forms display, especially on mobile devices. This guide covers best practices for embedding Flashquotes forms on Wix sites and solutions to common issues.
Wix enforces a 320px width limit on mobile iframes and uses sandboxed rendering that can break responsive design. Test your embed on mobile before going live.

Known Wix Limitations

​
Mobile Display Issues

Wix’s mobile rendering differs from other website builders:
  • 320px width constraint: All mobile content displays at 320px width regardless of device capabilities
  • Non-responsive preview: Chrome Developer Tools cannot accurately preview Wix mobile layouts
  • Sandboxed iframes: Wix wraps embeds in an additional iframe that prevents natural responsive behavior
  • Fixed height containers: Dynamic height adjustments may not work as expected

​
What This Means for Your Forms

  • Multi-step forms may appear cramped on mobile
  • Form fields might not scale properly
  • Scrolling within the iframe may be required
  • Dynamic height changes between form steps may not function
For the best user experience, use a hybrid approach:

​
Desktop: Full Embed

Embed your Flashquotes form normally for desktop users where space isn’t constrained. Replace the iframe with a button that links to your form’s Share Link. Implementation steps:
  1. Generate a Share Link in your Flashquotes dashboard
  2. In Wix’s mobile editor, hide the HTML iframe element
  3. Add a button with text like “Get Custom Pricing” or “Request Quote”
  4. Link the button to your Share Link URL
This ensures mobile users get the full, responsive form experience without Wix’s constraints. Additional Wix resources: Video tutorial: How to fix iframes on Wix mobile

If You Choose to Embed on Mobile

If you prefer to keep the iframe embed on mobile, follow these optimization steps:
  • Ensure the embed code is wrapped in a div with at least 320px width and 650px height
  • Test the embed on actual mobile devices, not just Wix’s mobile preview

​
Google Analytics and Ad Tracking

Wix’s sandboxed iframe also prevents your embedded form from reading the visitor’s original traffic source, so Google Analytics records form events as direct instead of the campaign or Google Ads click that drove the visit. If you track conversions with Google Analytics, add the Flashquotes attribution script to your Wix header.

Add one script to your Wix site’s header so form events are attributed to the right source instead of direct.
