Question

我想像这样创建CSS3加载圈：

enter image description here

内圈将使用计时器增长。

问题是什么技术可以用来像这样发展内圈？

我有这个CSS代码：

.circle {
width:100px;
height:100px;
border-radius:50px;
background:#fff;
}

.circle只是div

外圈可以用作背景图像，因为它是静态的。它永远不会改变，只有内在的会根据计时器而改变。

Answer 1

HTML

在第一个例子中，只创建两个div，并且由于border-radius属性，它们将采用圆形。

<div class="ball"></div>
<div class="ball1"></div>

CSS

对于CSS样式非常简单，只需使用所需图形的参数，关于动画只需使用transform：rotateproperty。

.ball {
    background-color: rgba(0,0,0,0);
    border: 5px solid rgba(0,183,229,0.9);
    opacity: .9;
    border-top: 5px solid rgba(0,0,0,0);
    border-left: 5px solid rgba(0,0,0,0);
    border-radius: 50px;
    box-shadow: 0 0 35px #2187e7;
    width: 50px;
    height: 50px;
    margin: 0 auto;
    -moz-animation: spin .5s infinite linear;
    -webkit-animation: spin .5s infinite linear;
}

.ball1 {
    background-color: rgba(0,0,0,0);
    border: 5px solid rgba(0,183,229,0.9);
    opacity: .9;
    border-top: 5px solid rgba(0,0,0,0);
    border-left: 5px solid rgba(0,0,0,0);
    border-radius: 50px;
    box-shadow: 0 0 15px #2187e7;
    width: 30px;
    height: 30px;
    margin: 0 auto;
    position: relative;
    top: -50px;
    -moz-animation: spinoff .5s infinite linear;
    -webkit-animation: spinoff .5s infinite linear;
}

@-moz-keyframes spin {
    0% {
        -moz-transform: rotate(0deg);
    }

    100% {
        -moz-transform: rotate(360deg);
    };
}

@-moz-keyframes spinoff {
    0% {
        -moz-transform: rotate(0deg);
    }

    100% {
        -moz-transform: rotate(-360deg);
    };
}

@-webkit-keyframes spin {
    0% {
        -webkit-transform: rotate(0deg);
    }

    100% {
        -webkit-transform: rotate(360deg);
    };
}

@-webkit-keyframes spinoff {
    0% {
        -webkit-transform: rotate(0deg);
    }

    100% {
        -webkit-transform: rotate(-360deg);
    };
}

第二个示例CSS3加载动画循环 HTML

第二个例子与标记的先例相同，你将在CSS中找到它的主要区别。

<div class="circle"></div>
<div class="circle1"></div>

CSS

在这个例子中，我们将对旋转进行操作，并且我们会插入一个动画，让我们有一个脉冲效果。此效果仅在第一个圆圈中有效。

.circle {
    background-color: rgba(0,0,0,0);
    border: 5px solid rgba(0,183,229,0.9);
    opacity: .9;
    border-right: 5px solid rgba(0,0,0,0);
    border-left: 5px solid rgba(0,0,0,0);
    border-radius: 50px;
    box-shadow: 0 0 35px #2187e7;
    width: 50px;
    height: 50px;
    margin: 0 auto;
    -moz-animation: spinPulse 1s infinite ease-in-out;
    -webkit-animation: spinPulse 1s infinite linear;
}

.circle1 {
    background-color: rgba(0,0,0,0);
    border: 5px solid rgba(0,183,229,0.9);
    opacity: .9;
    border-left: 5px solid rgba(0,0,0,0);
    border-right: 5px solid rgba(0,0,0,0);
    border-radius: 50px;
    box-shadow: 0 0 15px #2187e7;
    width: 30px;
    height: 30px;
    margin: 0 auto;
    position: relative;
    top: -50px;
    -moz-animation: spinoffPulse 1s infinite linear;
    -webkit-animation: spinoffPulse 1s infinite linear;
}

@-moz-keyframes spinPulse {
    0% {
        -moz-transform: rotate(160deg);
        opacity: 0;
        box-shadow: 0 0 1px #2187e7;
    }

    50% {
        -moz-transform: rotate(145deg);
        opacity: 1;
    }

    100% {
        -moz-transform: rotate(-320deg);
        opacity: 0;
    };
}

@-moz-keyframes spinoffPulse {
    0% {
        -moz-transform: rotate(0deg);
    }

    100% {
        -moz-transform: rotate(360deg);
    };
}

@-webkit-keyframes spinPulse {
    0% {
        -webkit-transform: rotate(160deg);
        opacity: 0;
        box-shadow: 0 0 1px #2187e7;
    }

    50% {
        -webkit-transform: rotate(145deg);
        opacity: 1;
    }

    100% {
        -webkit-transform: rotate(-320deg);
        opacity: 0;
    };
}

@-webkit-keyframes spinoffPulse {
    0% {
        -webkit-transform: rotate(0deg);
    }

    100% {
        -webkit-transform: rotate(360deg);
    };
}

第三个示例CSS3加载动画循环 HTML

在这个最新的例子中，我们发现了一个简单的循环，由于transform：scale属性，它是动画的。标记比其前任更长，但这可能会根据您要插入的块而有所不同。

<div id="block_1" class="barlittle"></div>
<div id="block_2" class="barlittle"></div>
<div id="block_3" class="barlittle"></div>
<div id="block_4" class="barlittle"></div>
<div id="block_5" class="barlittle"></div>

CSS

这里的样式更容易处理，因为我们要将效果应用于动画：每个块的延迟属性。

.barlittle {
    background-color: #2187e7;
    background-image: -moz-linear-gradient(45deg, #2187e7 25%, #a0eaff);
    background-image: -webkit-linear-gradient(45deg, #2187e7 25%, #a0eaff);
    border-left: 1px solid #111;
    border-top: 1px solid #111;
    border-right: 1px solid #333;
    border-bottom: 1px solid #333;
    width: 10px;
    height: 10px;
    float: left;
    margin-left: 5px;
    opacity: 0.1;
    -moz-transform: scale(0.7);
    -webkit-transform: scale(0.7);
    -moz-animation: move 1s infinite linear;
    -webkit-animation: move 1s infinite linear;
}

#block_1 {
    -moz-animation-delay: .4s;
    -webkit-animation-delay: .4s;
}

#block_2 {
    -moz-animation-delay: .3s;
    -webkit-animation-delay: .3s;
}

#block_3 {
    -moz-animation-delay: .2s;
    -webkit-animation-delay: .2s;
}

#block_4 {
    -moz-animation-delay: .3s;
    -webkit-animation-delay: .3s;
}

#block_5 {
    -moz-animation-delay: .4s;
    -webkit-animation-delay: .4s;
}

@-moz-keyframes move {
    0% {
        -moz-transform: scale(1.2);
        opacity: 1;
    }

    100% {
        -moz-transform: scale(0.7);
        opacity: 0.1;
    };
}

@-webkit-keyframes move {
    0% {
        -webkit-transform: scale(1.2);
        opacity: 1;
    }

    100% {
        -webkit-transform: scale(0.7);
        opacity: 0.1;
    };
}
