水滴融合效果
CSS
- 首先设置一个容器，在容器里写三个div
<div class="container">
<div class="drop"></div>
<div class="drop"></div>
<div class="drop"></div>
</div>
- 在把这个容器居中
.container {
display: flex;
justify-content: center;
align-items: center;
min-height: 100vh;
background: #000;
flex-direction: column; /* 使三个圆形垂直排列 */
}
- 设置水滴样式
.drop {
width: 100px;
height: 100px;
background-color: #fff;
border-radius: 50%;
}
效果如下
- 通过绝对定位，使三个球重叠
.drop {
width: 100px;
height: 100px;
background-color: #fff;
border-radius: 50%;
position: absolute;
}
- 然后再设置三个球的位置，和过滤度
.drop {
width: 100px;
height: 100px;
background-color: #fff;
border-radius: 50%;
position: absolute;
filter: blur(20px);
}
.drop:nth-child(2) {
transform: translateY(-80px);
}
.drop:nth-child(3) {
transform: translateY(-130px);
}
如下效果
- 在container里添加对比度来模糊边框 ，重新绘制出一个实边，从而达到融合到一起的效果
.container {
display: flex;
justify-content: center;
align-items: center;
min-height: 100vh;
background: #000;
flex-direction: column; /* 使三个圆形垂直排列 */
filter: contrast(30);
}
效果如下
- 在 HTML 中新增一个用来装水的容器
<!-- 用来装水的容器 -->
<div class="collection"></div>
<span>80%</span>
- CSS 样式如下
.collection {
width: 100px;
height: 100px;
background-color: #fff;
border-radius: 50%;
filter: blur(20px);
}
效果如下
- 编写CSS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);
}
}
- 给drop设置动画
.drop {
width: 100px;
height: 100px;
background-color: #fff;
border-radius: 50%;
position: absolute;
filter: blur(20px);
opacity: 0;
animation: 2.5s drop linear infinite;
}
即可达到以下效果
- 给drop的另两个分别设置动画延迟
.drop:nth-child(2) {
animation-delay: 0.5s;
}
.drop:nth-child(3) {
animation-delay: 0.7s;
}
效果如下
- 编写collection的动画
@keyframes collection {
0% {
transform: scale(1) rotate(0deg);
}
50% {
transform: scale(1.3) rotate(180deg);
width: 90px;
border-top-left-radius: 40%;
border-bottom-left-radius: 45%;
}
100% {
transform: scale(1) rotate(360deg);
}
}
.collection {
width: 100px;
height: 100px;
background-color: #fff;
border-radius: 50%;
filter: blur(20px);
animation: 3s collection linear infinite;
}
效果如下
