Sorry, aber ich bin Amateur :-( ich habe folgendes Scripts - was ist denn falsch?

<style type="text/css">
main {
        background: transparent;
        border-color: transparent;
}

#gallery {
        position: relative;
        background: none;
        border: none;
}

#gallery figure {
        position: absolute;
        top: 0;
        left: 60px;
        z-index: 1;
        -webkit-animation: wechseln 15s infinite;
        animation: wechseln 15s infinite;
}

@keyframes wechseln {
        0% {opacity: 1;}
        25% {opacity: 1;}
        40% {opacity: 0;}
        92% {opacity: 0;}
        100% {opacity: 1;}
}

@-webkit-keyframes wechseln {
        0% {opacity: 1;}
        25% {opacity: 1;}
        40% {opacity: 0;}
        92% {opacity: 0;}
        100% {opacity: 1;}
}

#gallery figure:nth-of-type(8) {
        animation-delay: 5s;
}
#gallery figure:nth-of-type(7) {
        animation-delay: 5s;
}
#gallery figure:nth-of-type(6) {
        animation-delay: 5s;
}
#gallery figure:nth-of-type(5) {
        animation-delay: 5s;
}
#gallery figure:nth-of-type(4) {
        animation-delay: 5s;
}
#gallery figure:nth-of-type(3) {
        animation-delay: 5s;
}
#gallery figure:nth-of-type(2) {
        animation-delay: 5s;
}
#gallery figure:nth-of-type(1) {
        animation-delay: 10s;
}
</style>
