css部分
用css3的動畫的 @keyframes 規則,製作輪轉圖。
body{
background: url("../img/1.jpg");
animation-name:myfirst;
animation-duration:12s;
/*變換時間*/
animation-delay:2s;
/*動畫開始時間*/
animation-iteration-count:infinite;
/*下一週期迴圈播放*/
animation-play-state:running;
/*動畫開始執行*/
}
@keyframes myfirst
{
0% {background:url("../img/1.jpg");}
34% {background:url("../img/2.jpg");}
67% {background:url("../img/3.jpg");}
100% {background:url("../img/1.jpg");}
}
.form{background: rgba(255,255,255,0.2);width:400px;margin:120px auto;}
/*陰影*/
.fa{display: inline-block;top: 27px;left: 6px;position: relative;color: #ccc;}
input[type="text"],input[type="password"]{padding-left:26px;}
.checkbox{padding-left:21px;}
