Question

我创建了一个动画微调器，使用＆＃34;披萨片＃34;由背景渐变。问题是我无法弄清楚起源应该是什么。动画继续跳跃。

我怎样才能摆脱跳跃？

HTML：

<div class="slices bar">
    <div></div>
    <div></div>
    <div></div>
    <div></div>
    <div></div>
    <div></div>
    <div></div>
    <div></div>
</div>

CSS：

.slices {
    width:100px;
    height:100px;
    position:relative;
    transform-origin: right bottom;
    -webkit-animation: spin 2.8s infinite steps(8);
    -moz-animation: spin 2.8s infinite steps(8);
    -ms-animation: spin 2.8s infinite steps(8);
    -o-animation: spin 2.8s infinite steps(8);
    animation: spin 2.8s infinite steps(8);
}
.slices.bar div {
    width: 100%;
    height: 100%;
    position: absolute;
    top: 35px;
    left: 45px;
    border-radius: 50%;
    background: linear-gradient(45deg, #CDCDCD 50%, transparent 50%) 0 0;
    background-repeat: no-repeat;
    background-size: 50% 50%;
    transform-origin: 56px 52px;
    /* container height / 2 */
}
@-webkit-keyframes spin {
    to {
        transform: rotate(1turn);
    }
}
@-moz-keyframes spin {
    to {
        transform: rotate(1turn);
    }
}
@-ms-keyframes spin {
    to {
        transform: rotate(1turn);
    }
}
@keyframes spin {
    to {
        transform: rotate(1turn);
    }
}
.slices.bar div:nth-child(1) {
    -webkit-transform: rotate(0deg);
    transform: rotate(0deg);
    background: linear-gradient(45deg, red 50%, transparent 50%) 0 0;
    background-repeat: no-repeat;
    background-size: 50% 50%;
}
.slices.bar div:nth-child(2) {
    -webkit-transform: rotate(45deg);
    transform: rotate(45deg);
}
.slices.bar div:nth-child(3) {
    -webkit-transform: rotate(90deg);
    transform: rotate(90deg);
}
.slices.bar div:nth-child(4) {
    -webkit-transform: rotate(135deg);
    transform: rotate(135deg);
}
.slices.bar div:nth-child(5) {
    -webkit-transform: rotate(180deg);
    transform: rotate(180deg);
}
.slices.bar div:nth-child(6) {
    -webkit-transform: rotate(225deg);
    transform: rotate(225deg);
}
.slices.bar div:nth-child(7) {
    -webkit-transform: rotate(270deg);
    transform: rotate(270deg);
}
.slices.bar div:nth-child(8) {
    -webkit-transform: rotate(315deg);
    transform: rotate(315deg);
}

我修改了你的代码。首先，我添加了一个容器div并简单地旋转它。 fiddle

HTML：

<div id='hold'>
    <div class="slices bar">
        <div></div>
        <div></div>
        <div></div>
        <div></div>
        <div></div>
        <div></div>
        <div></div>
        <div></div>
    </div>
</div>

CSS：

.slices {
    width:100px;
    height:100px;
    position:relative;
    margin-top: -31px;
    margin-left: -45px;
    transform-origin: right bottom;
    /*-webkit-animation: spin 2.8s infinite steps(8);
    -moz-animation: spin 2.8s infinite steps(8);
    -ms-animation: spin 2.8s infinite steps(8);
    -o-animation: spin 2.8s infinite steps(8);
    animation: spin 2.8s infinite steps(8);*/
}
#hold {
    width: 112px;
    height: 112px;
    border-radius: 50%;
    overflow: hidden;
    -webkit-animation: spin 2.8s infinite steps(8);
    -moz-animation: spin 2.8s infinite steps(8);
    -ms-animation: spin 2.8s infinite steps(8);
    -o-animation: spin 2.8s infinite steps(8);
    animation: spin 2.8s infinite steps(8);
}
.slices.bar div {
    width: 100%;
    height: 100%;
    position: absolute;
    top: 35px;
    left: 45px;
    border-radius: 50%;
    background: linear-gradient(45deg, #CDCDCD 50%, transparent 50%) 0 0;
    background-repeat: no-repeat;
    background-size: 50% 50%;
    transform-origin: 56px 52px;
    /* container height / 2 */
}
@-webkit-keyframes spin {
    to {
        transform: rotate(1turn);
    }
}
@-moz-keyframes spin {
    to {
        transform: rotate(1turn);
    }
}
@-ms-keyframes spin {
    to {
        transform: rotate(1turn);
    }
}
@keyframes spin {
    to {
        transform: rotate(1turn);
    }
}
.slices.bar div:nth-child(1) {
    -webkit-transform: rotate(0deg);
    transform: rotate(0deg);
    background: linear-gradient(45deg, red 50%, transparent 50%) 0 0;
    background-repeat: no-repeat;
    background-size: 50% 50%;
}
.slices.bar div:nth-child(2) {
    -webkit-transform: rotate(45deg);
    transform: rotate(45deg);
}
.slices.bar div:nth-child(3) {
    -webkit-transform: rotate(90deg);
    transform: rotate(90deg);
}
.slices.bar div:nth-child(4) {
    -webkit-transform: rotate(135deg);
    transform: rotate(135deg);
}
.slices.bar div:nth-child(5) {
    -webkit-transform: rotate(180deg);
    transform: rotate(180deg);
}
.slices.bar div:nth-child(6) {
    -webkit-transform: rotate(225deg);
    transform: rotate(225deg);
}
.slices.bar div:nth-child(7) {
    -webkit-transform: rotate(270deg);
    transform: rotate(270deg);
}
.slices.bar div:nth-child(8) {
    -webkit-transform: rotate(315deg);
    transform: rotate(315deg);
}

改变原点，让动画不跳
