Technical how-to
Squarespace and Wix are both fully capable of hosting an embedded calculator — the process just looks a little different on each platform.
See it on a real page
Try the live calculator embedded exactly as your customers would see it.
View the demo →Add a “Code Block” to the page where the calculator should appear, then paste the embed snippet directly into it — Squarespace renders the block's contents on the live page exactly as provided.
Use the “Embed a Widget” or “HTML iframe” element from the Wix editor's add-elements menu, paste the snippet in, and resize the element on the page as needed to fit your layout.
Preview the live page (not just the editor) after adding the embed, since both platforms can apply their own layout constraints that affect how an embedded element displays.
Both are straightforward once you know which specific element to use — Code Block on Squarespace, Embed/HTML element on Wix.
Yes, both platforms generally allow embed elements to be placed within existing page layouts, not just standalone pages.
