Paste the code to you ASP event website’s HTML field.
Next, go to your ASP event 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 ASP’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 Back to Top Button widget on your ASP event website.
