问题:

I want to make a rotation of my loading icon by CSS.

I have an icon and the following code:

<style>
#test {
    width: 32px;
    height: 32px;
    background: url('refresh.png');
}

.rotating {
    -webkit-transform: rotate(360deg);
    -webkit-transition-duration: 1s;
    -webkit-transition-delay: now;
    -webkit-animation-timing-function: linear;
    -webkit-animation-iteration-count: infinite;
}
</style>

<div id='test' class='rotating'></div>

But it doesn't work. How can the icon be rotated using CSS?

回答1:

@-webkit-keyframes rotating /* Safari and Chrome */ {
  from {
    -webkit-transform: rotate(0deg);
    -o-transform: rotate(0deg);
    transform: rotate(0deg);
  }
  to {
    -webkit-transform: rotate(360deg);
    -o-transform: rotate(360deg);
    transform: rotate(360deg);
  }
}
@keyframes rotating {
  from {
    -ms-transform: rotate(0deg);
    -moz-transform: rotate(0deg);
    -webkit-transform: rotate(0deg);
    -o-transform: rotate(0deg);
    transform: rotate(0deg);
  }
  to {
    -ms-transform: rotate(360deg);
    -moz-transform: rotate(360deg);
    -webkit-transform: rotate(360deg);
    -o-transform: rotate(360deg);
    transform: rotate(360deg);
  }
}
.rotating {
  -webkit-animation: rotating 2s linear infinite;
  -moz-animation: rotating 2s linear infinite;
  -ms-animation: rotating 2s linear infinite;
  -o-animation: rotating 2s linear infinite;
  animation: rotating 2s linear infinite;
}

<div 
  class="rotating"
  style="width: 100px; height: 100px; line-height: 100px; text-align: center;" 
 >Rotate</div>

Working nice:

#test {
    width: 11px;
    height: 14px;
    background: url('data:image/gif;base64,R0lGOD lhCwAOAMQfAP////7+/vj4+Hh4eHd3d/v7+/Dw8HV1dfLy8ubm5vX19e3t7fr 6+nl5edra2nZ2dnx8fMHBwYODg/b29np6eujo6JGRkeHh4eTk5LCwsN3d3dfX 13Jycp2dnevr6////yH5BAEAAB8ALAAAAAALAA4AAAVq4NFw1DNAX/o9imAsB tKpxKRd1+YEWUoIiUoiEWEAApIDMLGoRCyWiKThenkwDgeGMiggDLEXQkDoTh CKNLpQDgjeAsY7MHgECgx8YR8oHwNHfwADBACGh4EDA4iGAYAEBAcQIg0Dk gcEIQA7');
}

@-webkit-keyframes rotating {
    from{
        -webkit-transform: rotate(0deg);
    }
    to{
        -webkit-transform: rotate(360deg);
    }
}

.rotating {
    -webkit-animation: rotating 2s linear infinite;
}

<div id='test' class='rotating'></div>

回答3:

/* ENDLESS ROTATE */
.rotate{
  -webkit-animation: rotate 1.5s linear infinite; 
          animation: rotate 1.5s linear infinite; 
}
@-webkit-keyframes rotate{ to{-webkit-transform: rotate(360deg); } }
@keyframes         rotate{ to{        transform: rotate(360deg); } }



/* SPINNER JUST FOR DEMO */
.spinner{
  display:inline-block; width: 50px; height: 50px;
  border-radius: 50%;
  box-shadow: inset -2px 0 0 2px #0bf;
}

<span class="spinner rotate"></span>

回答4:

Without any prefixes, e.g. at it's simplest:

.loading-spinner {
  animation: rotate 1.5s linear infinite;
}

@keyframes rotate {
  to {
    transform: rotate(360deg);
  }
}

回答5:

Works in all browsers

.rotate{
 animation: loading 3s linear infinite;
 @keyframes loading {
  0% { 
    transform: rotate(0); 
  }
  100% { 
    transform: rotate(360deg);
  }
 }
}

<style>
div
{  
     height:200px;
     width:200px;
     -webkit-animation: spin 2s infinite linear;    
}
@-webkit-keyframes spin {
    0%  {-webkit-transform: rotate(0deg);}
    100% {-webkit-transform: rotate(360deg);}   
}

</style>
</head>

<body>
<div><img src="1.png" height="200px" width="200px"/></div>
</body>
