如何使用CSS将形状组合成一个云？

Question

所以我主要尝试使用div和CSS创建云。我几乎没有div形状为圆形或斑点的想法，其想法是将它们合并为一个，以便它们看起来像云。

.cloud-body{
 
  width:250px;
  height:200px;
  background: linear-gradient(blue,blueviolet);
  margin-left: 30%;
  margin-top:20%;
  border-radius:50%;
  
}
.blob1{
  width: 100px;
  height: 100px;
  background: blue;
  border-radius:50%;
  position:relative;
  bottom: 200px;
  left: 60%;
 
}
.blob2{
  width: 200px;
  height: 150px;
  background: linear-gradient(blueviolet, blue);
  border-radius:50%;
  position:relative;
  bottom: 200px;
  left: 150px;
}
.blob3{
  width: 200px;
  height: 150px;
  background: linear-gradient(blueviolet, blue);
  border-radius:50%;
  position:relative;
  bottom: 400px;
  left: 400px
}

<div class="wrapper">
<div class="cloud-body"></div>
<div class="blob1"></div>
<div class="blob2"></div>
<div class="blob3"></div>
</div>

但是它们看起来就像是彼此叠放的不同blob（如divs所期望的那样）。结合它们的方法是什么？或更具体地说，是使每种形状之间的边界消失吗？这是我正在处理的Codepen上pen for this的链接。

您可以考虑多个背景来创建具有一个元素的云。您可以轻松添加任意数量和大小的任意数量的圆/椭圆。一个半径值将给出一个圆，而两个值将给出一个椭圆

.cloud {
  width:200px;
  height:150px;
  border-radius: 0 0 50px 50px;
  background:
  /*                radius                            position  / 2xradius*/
  radial-gradient(35px 30px,blue 98%,transparent 100%) 20% 30%  /70px    60px,
  radial-gradient(50px 45px,blue 98%,transparent 100%) 50% 50%  /100px   90px,
  radial-gradient(50px     ,blue 98%,transparent 100%) 100% 100%/100px   100px,
  radial-gradient(40px     ,blue 98%,transparent 100%) 0 100%   /80px    80px,
  /* base of the cloud */
  linear-gradient(blue,blue) bottom/100% 40px;;
  background-repeat:no-repeat;
}

<div class="cloud"></div>

如果要使用渐变作为着色，则可以使用mask完成。您只需使用先前在mask属性内定义的渐变即可：

.cloud {
  width:200px;
  height:150px;
  border-radius: 0 0 50px 50px;
  background:linear-gradient(60deg,red,blue);
  -webkit-mask:
  radial-gradient(35px 30px,blue 98%,transparent 100%) 20% 30%  /70px   60px,
  radial-gradient(50px 45px,blue 98%,transparent 100%) 50% 50%  /100px  90px,
  radial-gradient(50px     ,blue 98%,transparent 100%) 100% 100%/100px  100px,
  radial-gradient(40px     ,blue 98%,transparent 100%) 0 100%   /80px   80px,
  
  linear-gradient(blue,blue) bottom/100% 40px;
  mask:
  radial-gradient(35px 30px,blue 98%,transparent 100%) 20% 30%  /70px   60px,
  radial-gradient(50px 45px,blue 98%,transparent 100%) 50% 50%  /100px  90px,
  radial-gradient(50px     ,blue 98%,transparent 100%) 100% 100%/100px  100px,
  radial-gradient(40px     ,blue 98%,transparent 100%) 0 100%   /80px   80px,
  
  linear-gradient(blue,blue) bottom/100% 40px;
  -webkit-mask-repeat:no-repeat;
  mask-repeat:no-repeat;
}

<div class="cloud"></div>

Answer 2

我建议使用此CSS云：

.cloud, .cloudshadow {
	width: 350px; height: 120px;
	background: #3498db;
	border-radius: 100px;
	position: relative;
	margin: 150px 50px;
}
.cloud:after, .cloud:before, .cloudshadow:after, .cloudshadow:before {
	content: '';
	position: absolute;
	background: #3498db;
	z-index: 1
}

.cloud:after, .cloudshadow:after {
	width: 100px; height: 100px;
	top: -50px; left: 50px;
	border-radius: 100px;
}
.cloud:before, .cloudshadow:before  {
	width: 180px; height: 180px;
	top: -90px; right: 50px;
	border-radius: 200px;
}

<div class="cloud">
    <div class="cloudshadow"></div>
</div>

响应式云：

svg {
  height: 50%;
  width: 50%;
}
path {
  fill: #3498DB;
  stroke: #3498DB;
  stroke-width: 2;
  stroke-linejoin: round;
}
path:hover {
  fill: aliceblue;
  stroke: lightskyblue;
}

<svg viewBox='0 0 105 105'>
  <path d='M 25,60 
           a 20,20 1 0,0 0,40 
           h 50 
           a 20,20 1 0,0 0,-40 
           a 10,10 1 0,0 -15,-10 
           a 15,15 1 0,0 -35,10  
           z' />
</svg>

      background: linear-gradient(blue, blueviolet);

      border-radius: 50%;

    }

    .blob1 {
      width: 130px;
      height: 100px;
      background: blue;
      border-radius: 50%;



    }

    .blob2 {
      width: 200px;
      height: 150px;
      background: linear-gradient(blueviolet, blue);
      border-radius: 50%;


    }

    .blob3 {
      width: 200px;
      height: 150px;
      background: linear-gradient(blueviolet, blue);
      border-radius: 50%;



    }

    div.cloud-body,
    div.blob1,
    div.blob2,
    div.blob3 {
      float: left;
    }

    .my-4 {
      margin-top: 2.4rem !important
    }
