4 Copy the code and paste it into your site
This is the code that puts the calculator above on your page. It has three parts:
- The calculator window. It shows the calculator from wealthplannerpro.ai inside your page, the same way a YouTube video is embedded.
- A one-line sizing script. It makes the window grow or shrink so there is no scroll bar inside it.
- A small credit line. It sits under the calculator and names WealthPlannerPro and Morrowgate Private Wealth as the source.
