I've found answers to my question but (being a newbie) I can't figure out how to apply them to the great animation example that I'm using.
How would I pause this on hover?
.quote:nth-child(1) {
-webkit-animation: cycle 15s 0s infinite linear;
-moz-animation: cycle 15s 0s infinite linear;
-ms-animation: cycle 15s 0s infinite linear;
-o-animation: cycle 15s 0s infinite linear;
animation: cycle 15s 0s infinite linear;
}
