加载动画效果
写在前面
在无限的时间的河流里,人生仅仅是微小又微小的波浪。——郭小川
实现效果
实现原理
- 通过2个伪元素来设置3条颜色边框
- 通过定位将3个圆弧边框层叠再一起，再通过旋转实现一个圆的效果
- 再给loading添加旋转动画即可
- 要实现文字转动的效果，只需让其反向旋转即可
实现代码
HTML
<div class="loading">
<span>loading...</span>
</div>
CSS
@keyframes rotate {
100%{
transform: rotateZ(360deg);
}
}
@keyframes rotate_ni {
100%{
transform: rotateZ(-360deg);
}
}
body {
margin: 0;
padding: 0;
background-color: black;
}
.loading {
position: relative;
width: 200px;
height: 200px;
box-sizing: border-box;
border-radius: 50%;
border-top: 10px solid #74b9ff;
animation: rotate 2s linear infinite;
margin: 100px auto;
}
.loading::before,.loading::after {
content: '';
width: 200px;
height: 200px;
position: absolute;
left: 0;
top: -10px;
box-sizing: border-box;
border-radius: 50%;
}
.loading::before {
border-top: 10px solid #a29bfe;
transform: rotate(120deg);
}
.loading::after {
border-top: 10px solid #55efc4 ;
transform: rotate(240deg);
}
span {
position: absolute;
color: snow;
width: 200px;
height: 200px;
text-align: center;
line-height: 200px;
animation: rotate_ni 2s linear infinite;
}
