Using different popup

How do I import a ‘dialog-mobile.css’ and ‘mcx-dialog.js’ file into my project?

dist/css/dialog-mobile.css
dist/mcx-dialog.js

from: Mobile-first Dialog Popup JavaScript Library - mcx-dialog-mobile | CSS Script

I think you can just drag and drop the required files in to the “Project Explorer” window.

Thanks I’ll try that.
