CSS3 animation (1): 5 types of pre-loaded animation effects and 35 types of CSS

Animation effect:

Preload Animation 1: Double Rotation

Rotate circles in two different directions. We define a CSS code for the rotation speed of the inner ring, that is, the inner ring is twice faster than the outer ring.
Implementation:

Html code:

<body style="background: #ffb83c;">    <div id="preloader-1">        <span></span>        <span></span>    </div></body>

Css code:

#preloader-1{    position: relative;}#preloader-1 span{    position: absolute;    border:8px solid #fff;    border-top:8px solid transparent;    border-radius: 999px;}#preloader-1 span:nth-child(1){    width:80px;    height: 80px;    animation: spin-1 2s infinite linear;}#preloader-1 span:nth-child(2){    top:20px;    left:20px;    width:40px;    height: 40px;    animation: spin-2 1s infinite linear;}@keyframes spin-1{    0%{transform: rotate(360deg); opacity: 1.0;}    50%{transform: rotate(180deg); opacity: 0.5;}    100%{transform: rotate(0deg);opacity: 0;}}@keyframes spin-2{    0%{transform: rotate(0deg); opacity: 0.5;}    50%{transform: rotate(180deg); opacity: 1;}    100%{transform: rotate(360deg);opacity: 0.5;}}

Preload Animation 2: staggered circles

The two circles are horizontally staggered and moved back and forth. Each circle has a separate reverse animation parameter.
Effect:

Html code:

<body style="background: #4ad3b4;">    <div id="preloader-2">        <span></span>        <span></span>    </div></body>

Css code:

#preloader-2{    position: relative;}#preloader-2 span{    position: absolute;    width:30px;    height: 30px;    background: #fff;    border-radius: 999px;}#preloader-2 span:nth-child(1){    animation: cross-1 1.5s infinite linear;}#preloader-2 span:nth-child(2){    animation: cross-2 1.5s infinite linear;}@keyframes cross-1{    0%{transform: translateX(0); opacity: 0.5;}    50%{transform: translateX(80px); opacity: 1;}    100%{transform: translateX(0);opacity: 0.5;}}@keyframes cross-2{    0%{transform: translateX(80px); opacity: 0.5;}    50%{transform: translateX(0); opacity: 1;}    100%{transform: translateX(80px);opacity: 0.5;}}
