前端用纯css 制作水滴特效充电效果,这个思路是我在b站看up主Steven做的,觉得很不错,然后自己也弄了一个,用于学习和记录;
实现思路:
1.先定义三个盒子和一个最底层的盒子,还有一个span 用于显示数字;
<div class="container">
<div class="drop"></div>
<div class="drop"></div>
<div class="drop"></div>
<div class="collection"></div>
<span>80%</span>
</div>
2.给大盒子定义基本样式,用弹性布局,这样三个水滴盒子(.drop)会左右上下居中排列;
filter的contrast(number); 调整图像对 比度。值是0%的话,图像会全黑。值是100%,图像不变。值可以超过100%,意味着会运用更低的对比。若没有设置值,默认是1。
.container {
display: flex;
justify-content: center;
align-items: center;
min-height: 100vh;
background-color: #000;
flex-direction: column;
filter: contrast(30);
}
3.给三个水滴盒子设置绝对定位,让它们重叠在一起;
filter: blur(20px);给水滴盒子设置模糊;
⚠️注意:给水滴盒子和收集的大盒子( .collection )设置模糊,然后再给父盒子设置对比度,这样在水滴滴落的过程中,会重新绘制图像,实现类似粘连的效果;
.drop {
width: 100px;
height: 100px;
background-color: #fff;
border-radius: 50%;
position: absolute;
filter: blur(20px);
opacity: 0;
animation: 2.5s drop linear infinite;
}
.collection {
width: 100px;
height: 100px;
background-color: #fff;
border-radius: 50%;
filter: blur(20px);
animation: 3s colleation linear infinite;
}
4.其次给水滴添加滴落的动画 drop ,以及收集盒子的动画 colleation ,自己把参数调到看着舒服为止;
/* 给水滴添加动画延时,避免三个水滴同时掉落 */
.drop:nth-child(2) {
animation-delay: .5s;
}
.drop:nth-child(3) {
animation-delay: .7s;
}
/* 水滴掉落动画 */
@keyframes drop {
0% {
transform: scale(0.7) translateY(-600%);
opacity: 0;
}
50% {
transform: scale(0.4) translateY(-80%);
opacity: 1;
}
100% {
transform: scale(0.3) translateY(0px);
}
}
/* 收集水滴的盒子添加的蠕动效果 */
@keyframes colleation {
0% {
transform: scale(1) rotate(0deg);
}
50% {
transform: scale(1.3) rotate(180deg);
width: 90px;
}
100% {
transform: scale(1) rotate(360deg);
}
}
