Paste the code to you Wix website’s HTML field.
Next, go to your Wix website and find the HTML field. It is most likely in the form of an HTML/Code widget or module which you can find on Wix’s dashboard. Add it to your page, and paste the code you’ve copied before to the HTML field. Save and update, and that’s it, you should have Common Ninja’s Free Bracket Maker app on your Wix website.
