If you sell your merchandise through a static website, insert the shopping cart button(s) by using whatever tool you used to construct the site. The example here uses Dreamweaver, the industry-standard tool used to create custom websites.
Open the page of the item using Dreamweaver and then click the Split button at the top of the workspace.
This opens the dual-panel view, where you see the underlying code and the page’s design.
Click the page where you want the shopping cart button to appear and then press Ctrl+V (on Mac, Command+V) to paste the code for the button into your page.
Again, this is the code that you copied.
Return to the tab in your browser where you created the shopping cart code, and then select and copy the code in the lower panel.
Press Ctrl+C (on a Mac, Command+C) to copy the code.
