旋转时它的旋转中心位置如何 - CSS动画

-1

我在css中创建了一个微调框，并且将它放置在没有动画的中心，但是当我开始动画时，我的旋转框移开。具体当我使用“@keyframes微调”规则。
我如何保持中心位置？旋转时它的旋转中心位置如何 - CSS动画

.spinner-animation{ 
 
    width: 500px; 
 
    height: 500px; 
 
    position: relative; 
 
    background: gray; 
 
} 
 

 
.spinner-animation > .spinner{ 
 
    width: 400px; 
 
    height: 400px; 
 
    position: absolute; 
 
    left: 50%; 
 
    top: 50%; 
 
    transform: translate(-50%,-50%); 
 
    border-radius: 50%; 
 
    box-shadow: inset 3px 3px 3px red; 
 
    animation: spinner 1.2s linear infinite; 
 
} 
 

 
.spinner-animation > .content{ 
 
    display: inline-block; 
 
    width: 300px; 
 
    height: 300px; 
 
    border-radius: 50%; 
 
    position: absolute; 
 
    left: 50%; 
 
    top: 50%; 
 
    transform: translate(-50%,-50%); 
 
    background-color: black; 
 
    text-align: center; 
 
    line-height: 300px; 
 
    color: white; 
 
} 
 

 

 
@keyframes spinner { 
 
    0% { 
 
    transform: rotate(0deg); 
 
    } 
 
    100% { 
 
    transform: rotate(360deg); 
 
    } 
 
}

<div class="spinner-animation"> 
 
    <span class="spinner"></span> 
 
    <div class="content">Loading...</div> 
 
</div>

谢谢大家对你的答案。 – DeveloperBeginner

我修改了动画，并增加了transform-origin的微调：d

.spinner-animation{ 
 
    width: 500px; 
 
    height: 500px; 
 
    position: relative; 
 
    background: gray; 
 
} 
 

 
.spinner-animation > .spinner{ 
 
    width: 400px; 
 
    height: 400px; 
 
    position: absolute; 
 
    left: 50%; 
 
    top: 50%; 
 
    transform-origin: top left; 
 
    transform: translate(-50%,-50%); 
 
    border-radius: 50%; 
 
    box-shadow: inset 3px 3px 3px red; 
 
    animation: spinner 1.2s linear infinite; 
 
} 
 

 
.spinner-animation > .content{ 
 
    display: inline-block; 
 
    width: 300px; 
 
    height: 300px; 
 
    border-radius: 50%; 
 
    position: absolute; 
 
    left: 50%; 
 
    top: 50%; 
 
    transform: translate(-50%,-50%); 
 
    background-color: black; 
 
    text-align: center; 
 
    line-height: 300px; 
 
    color: white; 
 
} 
 

 

 
@keyframes spinner { 
 
    0% { 
 
    transform: rotate(0deg) translate(-50%,-50%); 
 
    } 
 
    100% { 
 
    transform: rotate(360deg) translate(-50%,-50%); 
 
    } 
 
}

<div class="spinner-animation"> 
 
    <span class="spinner"></span> 
 
    <div class="content">Loading...</div> 
 
</div>

Flex的框溶液：显示作为flex元素的父元素，并对齐（垂直方向）和证明（水平地）其绝对定位的儿童到中心。

.spinner-animation{ 
 
    width: 500px; 
 
    height: 500px; 
 
    background: gray; 
 
    display: flex; 
 
    align-items: center; 
 
    justify-content: center; 
 
} 
 

 
.spinner-animation > .spinner{ 
 
    width: 400px; 
 
    height: 400px; 
 
    position: absolute; 
 
    border-radius: 50%; 
 
    box-shadow: inset 3px 3px 3px red; 
 
    animation: spinner 1.2s linear infinite; 
 
} 
 

 
.spinner-animation > .content{ 
 
    display: inline-block; 
 
    width: 300px; 
 
    height: 300px; 
 
    border-radius: 50%; 
 
    position: absolute; 
 
    background-color: black; 
 
    text-align: center; 
 
    line-height: 300px; 
 
    color: white; 
 
} 
 

 

 
@keyframes spinner { 
 
    0% { 
 
    transform: rotate(0deg); 
 
    } 
 
    100% { 
 
    transform: rotate(360deg); 
 
    } 
 
}

<div class="spinner-animation">

把span在另一个容器和应用position: absolute到这个容器

.spinner-animation { 
 
    width: 500px; 
 
    height: 500px; 
 
    position: relative; 
 
    background: gray; 
 
} 
 

 
.holder { 
 
    position: absolute; 
 
    width: 400px; 
 
    height: 400px; 
 
    left: 50%; 
 
    top: 50%; 
 
    transform: translate(-50%, -50%); 
 
} 
 

 
.holder .spinner { 
 
    display: block; 
 
    width: 100%; 
 
    height: 100%; 
 
    border-radius: 50%; 
 
    box-shadow: inset 3px 3px 3px red; 
 
    animation: spinner 1.2s linear infinite; 
 
} 
 

 
.spinner-animation>.content { 
 
    display: inline-block; 
 
    width: 300px; 
 
    height: 300px; 
 
    border-radius: 50%; 
 
    position: absolute; 
 
    left: 50%; 
 
    top: 50%; 
 
    transform: translate(-50%, -50%); 
 
    background-color: black; 
 
    text-align: center; 
 
    line-height: 300px; 
 
    color: white; 
 
} 
 

 
@keyframes spinner { 
 
    0% { 
 
    transform: rotate(0deg); 
 
    } 
 
    100% { 
 
    transform: rotate(360deg); 
 
    } 
 
}

<div class="spinner-animation"> 
 
    <div class="holder"> 
 
    <span class="spinner"></span> 
 
    </div> 
 
    <div class="content">Loading...</div> 
 
</div>

在动画中的transform被覆盖translate()定位，您需要将translate()添加到您的动画transform属性中。

.spinner-animation{ 
 
    width: 500px; 
 
    height: 500px; 
 
    position: relative; 
 
    background: gray; 
 
} 
 

 
.spinner-animation > .spinner{ 
 
    width: 400px; 
 
    height: 400px; 
 
    position: absolute; 
 
    left: 50%; 
 
    top: 50%; 
 
    transform: translate(-50%,-50%); 
 
    border-radius: 50%; 
 
    box-shadow: inset 3px 3px 3px red; 
 
    animation: spinner 1.2s linear infinite; 
 
} 
 

 
.spinner-animation > .content{ 
 
    display: inline-block; 
 
    width: 300px; 
 
    height: 300px; 
 
    border-radius: 50%; 
 
    position: absolute; 
 
    left: 50%; 
 
    top: 50%; 
 
    transform: translate(-50%,-50%); 
 
    background-color: black; 
 
    text-align: center; 
 
    line-height: 300px; 
 
    color: white; 
 
} 
 

 

 
@keyframes spinner { 
 
    0% { 
 
    transform: translate(-50%,-50%) rotate(0deg); 
 
    } 
 
    100% { 
 
    transform: translate(-50%,-50%) rotate(360deg); 
 
    } 
 
}

<div class="spinner-animation"> 
 
    <span class="spinner"></span> 
 
    <div class="content">Loading...</div> 
 
</div>
