用CSS实现加载的动画效果
用纯CSS实现加载的一些动态效果,可以把加载效果中的元素分成很多个小部分,每个部分都有动画,每个部分的动画再设置相应的延迟效果,这样,看起来就是连贯的加载动画效果。代码如下:
1、效果1
<div className='loading-con'> <div className='load-dian dian1'></div> <div className='load-dian dian2'></div> <div className='load-dian dian3'></div> <div className='load-dian dian4'></div> <div className='load-dian dian5'></div> <div className='text-loading'>加载中</div> </div>
.loading-con{ position: absolute; top: 50%; width: 100px; height: 100px; left: 50%; transform: translate(-50%,-50%); background: rgba(0,0,0,0.65); border-radius: 8px; }
.load-dian{ position: absolute; width: 8px; height: 8px; border-radius: 5px; background: #fff; top: 40%; -webkit-animation: Loading-delay 1.2s infinite ease-in-out both; animation: Loading-delay 1.2s infinite ease-in-out both; }
.dian1{ left: 15%; -webkit-animation-delay: -1.1s; animation-delay: -1.1s; } .dian2{ left: 30%; -webkit-animation-delay: -1s; animation-delay: -1s; } .dian3{ left: 45%; -webkit-animation-delay: -0.9s; animation-delay: -0.9s; } .dian4{ left: 60%; -webkit-animation-delay: -0.8s; animation-delay: -0.8s; } .dian5{ left: 75%; -webkit-animation-delay: -0.7s; animation-delay: -0.7s; }
@-webkit-keyframes Loading-delay { 0%, 100% { -webkit-transform: scale(0); transform: scale(0); } 40% { -webkit-transform: scale(1); transform: scale(1); } }
2、效果2
<div className='loading-con-o'>
<div className='load-item load-item-1'></div>
<div className='load-item load-item-2'></div>
<div className='load-item load-item-3'></div>
<div className='load-item load-item-4'></div>
<div className='load-item load-item-5'></div>
<div className='load-item load-item-6'></div>
<div className='load-item load-item-7'></div>
<div className='load-item load-item-8'></div>
<div className='load-item load-item-9'></div>
<div className='load-item load-item-10'></div>
<div className='load-item load-item-11'></div>
<div className='load-item load-item-12'></div>
<div className='text-loading'>加载中</div>
</div>
.loading-con-o{ position: absolute; top:50%; width: 100px; height: 100px; left: 50%; transform: translate(-50%,-50%); background: rgba(0,0,0,0.65); border-radius: 8px; } .load-item{ position: absolute; width: 8px; height: 2px; border-radius: 2px; background: #fff; top: 40%; left: calc(50% + 8px); transform-origin:-100%; -webkit-animation: Loading-delay1 1.2s infinite ease-in-out both; animation: Loading-delay1 1.2s infinite ease-in-out both; } @-webkit-keyframes Loading-delay1 { 0%, 100% { opacity: 1; } 40% { opacity: 0.1; } } .load-item-1{ -webkit-transform: rotate(30deg); transform: rotate(30deg); -webkit-animation-delay: -1.1s; animation-delay: -1.1s; } .load-item-2{ -webkit-transform: rotate(60deg); transform: rotate(60deg); -webkit-animation-delay: -1.0s; animation-delay: -1.0s; } .load-item-3{ -webkit-transform: rotate(90deg); transform: rotate(90deg); -webkit-animation-delay: -0.9s; animation-delay: -0.9s; } .load-item-4{ -webkit-transform: rotate(120deg); transform: rotate(120deg); -webkit-animation-delay: -0.8s; animation-delay: -0.8s; } .load-item-5{ -webkit-transform: rotate(150deg); transform: rotate(150deg); -webkit-animation-delay: -0.7s; animation-delay: -0.7s; } .load-item-6{ -webkit-transform: rotate(180deg); transform: rotate(180deg); -webkit-animation-delay: -0.6s; animation-delay: -0.6s; } .load-item-7{ -webkit-transform: rotate(210deg); transform: rotate(210deg); -webkit-animation-delay: -0.5s; animation-delay: -0.5s; } .load-item-8{ -webkit-transform: rotate(240deg); transform: rotate(240deg); -webkit-animation-delay: -0.4s; animation-delay: -0.4s; } .load-item-9{ -webkit-transform: rotate(270deg); transform: rotate(270deg); -webkit-animation-delay: -0.3s; animation-delay: -0.3s; } .load-item-10{ -webkit-transform: rotate(300deg); transform: rotate(300deg); -webkit-animation-delay: -0.2s; animation-delay: -0.2s; } .load-item-11{ -webkit-transform: rotate(330deg); transform: rotate(330deg); -webkit-animation-delay: -0.1s; animation-delay: -0.1s; } .load-item-12{ -webkit-transform: rotate(360deg); transform: rotate(360deg); -webkit-animation-delay: -0s; animation-delay: -0s; }
