looks cool, but the share button, shares your codepen not the quote.
i did it by calling this method:
var url = "https://twitter.com/intent/tweet";
var tweet = yourQuote + " " +yourAuthor;
I don’t know if you’ll be able to do this because from the looks of it your quotes are not strings but part of an image. Maybe you can google how to tweet an image, and that’ll solve your problem.
Alternatively you can use text for your quotes.
Store them in an array, or use an API to fetch them. I used the forismatic API: https://forismatic.com/en/api/
