>>1312i once tried using a rotating coupon code system on my site, kinda like this: ⚡
@keyframes rotate {from { transform:rotate(0deg); }to {transform :rotatate(turn(-1/4));}}. coupon-code{animation-name :-webkit-rotation,rotation;-moz-animation-duration.5s.283976s; /'' for Firefox ''/.worked great to keep things fresh and users guessing! but ya gotta test it on all browsers first
