css - Webkit transform: rotate -

-

i've got code:

html:

<section class="progress">     <div class="spinner icon-spinner" aria-hidden="true"></div>   <p class="label">loading</p> </section>

css:

@font-face {     font-family: 'icomoon';     src:url('http://s3.amazonaws.com/icomoonfonts/4/6/f.eot');     src:url('http://s3.amazonaws.com/icomoonfonts/4/6/f.eot?#iefix') format('embedded-opentype'),         url('http://s3.amazonaws.com/icomoonfonts/4/6/f.woff') format('woff'),         url('http://s3.amazonaws.com/icomoonfonts/4/6/f.ttf') format('truetype'),         url('http://s3.amazonaws.com/icomoonfonts/4/6/f.svg#icomoon') format('svg');     font-weight: normal;     font-style: normal; }  .icon-spinner:before {     font-family: 'icomoon';     speak: none;     font-style: normal;     font-weight: normal;     line-height: 1;     -webkit-font-smoothing: antialiased;     content: "\e002"; }  @keyframes anim-rotate {     0% {         transform: rotate(0);     opacity: 1;     }   50% {     opacity: .7;   }     100% {         transform: rotate(359deg);     opacity: 1;     } } .spinner {     display: inline-block;     font-size:64px;     height: 64px;     line-height: 1;     margin: .1em;     animation: anim-rotate 3s infinite linear;     color: rgba(223,78,107, 1); } body {   text-align: center;     line-height: 1.5;     background: #fff; } .progress {   margin:2em; } .progress .label {   color:#777;   margin:0;   font-size:16px;   font-family: tahoma,verdana,sans-serif; }

example: http://codepen.io/anon/pen/bfkaa/

why rotate(0deg); -> rotate(359deg); shakes in chrome during rotation? example in ff working. can make code changes there obtain smooth rotation in chrome?

try ...

  @keyframes anim-rotate {     0% {         transform: rotate(0);     opacity: 1;     }   50% {     opacity: 1;   }     100% {         transform: rotate(360deg);     opacity: 1;     }
