Ich habe den folgenden Code:http: //jsfiddle.net/odj8v0x4.

function stopGlobe() {
    $('.mapfront').removeClass('mapfront-anim');
    $('.mapback').removeClass('mapback-anim');
}

function startGlobe() {
    $('.mapfront').addClass('mapfront-anim');
    $('.mapback').addClass('mapback-anim');
}

@keyframes mapfront_spin {
    0% {
        background-position: 1400px 0%;
    }
    100% {
        background-position: 0 0%;
    }
}
@keyframes mapback_spin {
    0% {
        background-position: 0 0%;
    }
    100% {
        background-position: 1400px 0%;
    }
}
@-webkit-keyframes mapfront_spin {
    0% {
        background-position: 1400px 0%;
    }
    100% {
        background-position: 0 0%;
    }
}
@-webkit-keyframes mapback_spin {
    0% {
        background-position: 0 0%;
    }
    100% {
        background-position: 1400px 0%;
    }
}
body {
    margin: 50px;
    background: #000;
}
.globe {
    width: 400px;
    height: 400px;
    position: relative;
}
.front {
    width: 400px;

.mapfront {
    background: url(http://dl.dropboxusercontent.com/u/17180596/CartoForeground.png) repeat-x;
}
.mapfront-anim {
    -webkit-animation: mapfront_spin 15s linear infinite;
    animation: mapfront_spin 15s linear infinite;
}
.mapback {

    position: absolute;
}
.mapback-anim {
    -webkit-animation: mapback_spin 15s linear infinite;
    animation: mapback_spin 15s linear infinite;
}

<div class="globe">
    <div class="front"></div>
    <div class="mapfront mapfront-anim"></div>
    <div class="mapback mapback-anim"></div>
    <div class="back"></div>
</div>

Nach dem Ausführen von Javascript-FunktionenstopGlobe() Animation stoppt, stoppt aber abrupt.

Kann ich die Animation reibungslos anhalten, um plötzliche Sprünge zu vermeiden, und die Animation an dem Punkt fortsetzen, an dem sie aufgehört hat?
