Hi - sorry for the stupid question;
Trying something really simple.
http://codepen.io/oneiamfor/pen/zGQdvj
This works in codepen environment, but not in my project/site.
When viewing the console and looking at the inspector, I can actually see the <div id="heartIcon" class="fa fa-heart" style="transform: matrix(1, 0, 0, 1, 0, 0);"></div> transform matrix values change as it tweens, but nothing changes or appears on screen.
Any beginner tips or ways i can troubleshoot further?
