写几个简单的加载中动画吧。
像前面三种都是相当于几个不同的点轮流来播放同一动画:变大变小。css3里面有一个用于尺度变换的方法:scale(x,y):定义 2D 缩放转换,改变元素的宽度和高度。
第四种就是一个小球从上往下跌落,再弹回去,在上面的时候速度最小,下面的时候速度最大。由于该小球只进行了上下的移动,所以我们可以运用:translateY(n):定义 2D 转换,沿着 Y 轴移动元素,从而实现小球沿Y方向来回移动。
废话不多说了,上代码。
首先,第一个加载中的动画:
1 <div id="loading1"> 2 <div class="demo1"></div> 3 <div class="demo1"></div> 4 <div class="demo1"></div> 5 <div class="demo1"></div> 6 <div class="demo1"></div> 7 </div>
html Code
1 .demo1 { 2 width: 4px; 3 height: 4px; 4 border-radius: 2px; 5 background: #68b2ce; 6 float: left; 7 margin: 0 3px; 8 animation: demo1 linear 1s infinite; 9 -webkit-animation: demo1 linear 1s infinite; 10 } 11 .demo1:nth-child(1){ 12 animation-delay:0s; 13 } 14 .demo1:nth-child(2){ 15 animation-delay:0.15s; 16 } 17 .demo1:nth-child(3){ 18 animation-delay:0.3s; 19 } 20 .demo1:nth-child(4){ 21 animation-delay:0.45s; 22 } 23 .demo1:nth-child(5){ 24 animation-delay:0.6s; 25 } 26 @keyframes demo1 27 { 28 0%,60%,100% {transform: scale(1);} 29 30% {transform: scale(2.5);} 30 } 31 @-webkit-keyframes demo1 32 { 33 0%,60%,100% {transform: scale(1);} 34 30% {transform: scale(2.5);} 35 }
css Code
第二个动画和第一个动画大同小异,第一个动画是将小球整体变大变小,第二动画则是将小方块的高度变大变小,而宽度不变:
1 <div id="loading2"> 2 <div class="demo2"></div> 3 <div class="demo2"></div> 4 <div class="demo2"></div> 5 <div class="demo2"></div> 6 <div class="demo2"></div> 7 </div>
html Code
1 .demo2 { 2 width: 4px; 3 height: 6px; 4 background: #68b2ce; 5 float: left; 6 margin: 0 3px; 7 animation: demo2 linear 1s infinite; 8 -webkit-animation: demo2 linear 1s infinite; 9 } 10 .demo2:nth-child(1){ 11 animation-delay:0s; 12 } 13 .demo2:nth-child(2){ 14 animation-delay:0.15s; 15 } 16 .demo2:nth-child(3){ 17 animation-delay:0.3s; 18 } 19 .demo2:nth-child(4){ 20 animation-delay:0.45s; 21 } 22 .demo2:nth-child(5){ 23 animation-delay:0.6s; 24 } 25 @keyframes demo2 26 { 27 0%,60%,100% {transform: scale(1);} 28 30% {transform: scaleY(3);} 29 } 30 @-webkit-keyframes demo2 31 { 32 0%,60%,100% {transform: scale(1);} 33 30% {transform: scaleY(3);} 34 }
css Code
第三个动画就需要将小球的位置定位一下,让几个小球整体上看起来围成一个圆,然后就像第一个一样使小球变大变小:
1 <div id="loading3"> 2 <div class="demo3"></div> 3 <div class="demo3"></div> 4 <div class="demo3"></div> 5 <div class="demo3"></div> 6 <div class="demo3"></div> 7 <div class="demo3"></div> 8 <div class="demo3"></div> 9 <div class="demo3"></div> 10 </div>
html Code
1 #loading3 { 2 position: relative; 3 width: 50px; 4 height: 50px; 5 } 6 .demo3 { 7 width: 4px; 8 height: 4px; 9 border-radius: 2px; 10 background: #68b2ce; 11 position: absolute; 12 animation: demo3 linear 0.8s infinite; 13 -webkit-animation: demo3 linear 0.8s infinite; 14 } 15 .demo3:nth-child(1){ 16 left: 24px; 17 top: 2px; 18 animation-delay:0s; 19 } 20 .demo3:nth-child(2){ 21 left: 40px; 22 top: 8px; 23 animation-delay:0.1s; 24 } 25 .demo3:nth-child(3){ 26 left: 47px; 27 top: 24px; 28 animation-delay:0.1s; 29 } 30 .demo3:nth-child(4){ 31 left: 40px; 32 top: 40px; 33 animation-delay:0.2s; 34 } 35 .demo3:nth-child(5){ 36 left: 24px; 37 top: 47px; 38 animation-delay:0.4s; 39 } 40 .demo3:nth-child(6){ 41 left: 8px; 42 top: 40px; 43 animation-delay:0.5s; 44 } 45 .demo3:nth-child(7){ 46 left: 2px; 47 top: 24px; 48 animation-delay:0.6s; 49 } 50 .demo3:nth-child(8){ 51 left: 8px; 52 top: 8px; 53 animation-delay:0.7s; 54 } 55 56 @keyframes demo3 57 { 58 0%,40%,100% {transform: scale(1);} 59 20% {transform: scale(3);} 60 } 61 @-webkit-keyframes demo3 62 { 63 0%,40%,100% {transform: scale(1);} 64 20% {transform: scale(3);} 65 }
css Code
接下来是第四个动画:
1 <div id="loading5"> 2 <div class="demo5"></div> 3 </div>
1 #loading5 { 2 width: 20px; 3 height: 100px; 4 border-bottom: 1px solid #68b2ce; 5 } 6 .demo5 { 7 width: 20px; 8 height: 20px; 9 border-radius: 10px; 10 background: #68b2ce; 11 animation: demo5 cubic-bezier(0.5,0.01,0.9,1) 0.6s infinite alternate; 12 -webkit-animation: demo5 cubic-bezier(0.5,0.01,0.9,1) 0.6s infinite alternate; 13 } 14 @keyframes demo5 15 { 16 0%{ 17 transform:translateY(0px); 18 -webkit-transform:translateY(0px); 19 } 20 100% { 21 transform:translateY(80px); 22 -webkit-transform:translateY(80px); 23 } 24 } 25 @-webkit-keyframes demo5 26 { 27 0%{ 28 transform:translateY(0px); 29 -webkit-transform:translateY(0px); 30 } 31 100% { 32 transform:translateY(80px); 33 -webkit-transform:translateY(80px); 34 } 35 }
css Code
以上就是这几个简单的加载中小动画的内容了。
