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。
