Frequently Asked Questions
Common questions about using NexTool calculators with Wix.
Can I use this on a free Wix site?
Yes. The HTML embed widget is available on all Wix plans, including the free tier. However, note that free Wix sites display Wix ads — upgrading to a Wix premium plan removes those.
How do I resize the calculator on Wix?
After adding the HTML embed widget, you can drag its corners to resize. Set the width to match your content area (usually 100%) and the height to at least 450px for optimal display.
Does it work with Wix ADI sites?
Yes. You can switch to the Wix Editor from an ADI-created site and add the HTML embed widget. Once added, you can switch back to ADI mode and the embed will be preserved.
Can I use Wix Velo with the calculator?
Absolutely. Wix Velo lets you add custom JavaScript that can communicate with the embedded calculator. This is useful for dynamic resizing, event tracking, or passing parameters.
