An alternative to popups.

Download the script here and include it on your webpage:

<script src="proxy.php?url=https%3A%2F%2Fgithub.com.%2Fpath%2Fto%2Funpopup.js"></script>

Do not include the script directly from GitHub (http://raw.github.com/...). The file is being served as text/plain and as such being blocked in Internet Explorer on Windows 7 for instance (because of the wrong MIME type). Bottom line: GitHub is not a CDN.

1. Add the class unpopup to the element that you'd like to convert.
2. Give that element a unique id
3. Enjoy!

Unpopup will create a background overlay to bring the element into focus and display a "close" icon. "Closing" the unpopup element will create a cookie that will prevent the unpopup from being shown again to the same user for the next week.

1. npm install
2. Edit configuration or code in src/
3. npm run build
