Wix requires a Premium plan to add custom code (the free plan doesn’t
allow custom <script> tags site-wide).
Paste the script tag:
<script
src="https://cdn.jsdelivr.net/gh/Ricky1800/leadbox@v0.2.0/dist/leadbox.min.js"
data-endpoint="YOUR_ENDPOINT_URL"
data-title="Get a Free Quote"
></script>
If you only want the widget on one page, choose that specific page instead of “All pages” in step 4 above — Wix lets you scope custom code per page.
z-index internally,
but if a specific Wix element still overlaps it, try data-position
values (bottom-left, top-right, top-left) to avoid the conflict.<script> tags the same way
as the live site.
