我画了使用不同通过CSS3云div标签我试图添加边框整个造型,但我有麻烦,因为每一个形状获得自己的边界如何申请边框整个云计算?

HTML:

<div id="cloud">
  <div id="bottom_c"></div>
  <div id="right_c"></div>
  <div id="left_c"></div>
</div>

CSS:

* {
  margin: 0;
  padding: 0;
  border: 0;
}

body{
  background-color: #4ca3ff;
}
#cloud {
  position: absolute;

}
#bottom_c {
  position: relative; top: 200px; left: 500px;
  width: 350px;
  height: 150px;
  background-color: #fff;
  border-radius: 100px;
  border: solid 5px black;
  z-index: 100;
}
#right_c{
  position: absolute; top: 140px; left: 640px;
  width: 150px;
  height: 150px;
  border-radius: 100%;

Answer 1:

你可以这样做没有任何额外的元素。 只需使用::before::after以相同的尺寸和圆形的顶级云气泡伪元素。 z-index保持在正确的层中的一切。

CSS:

body{
    background-color: #4ca3ff;
}

#cloud {
    height: 230px;
    margin: 40px;
    position: relative;
    width: 400px;
}

#cloud div {
    border: solid 5px black;
}

#bottom_c {
    background-color: #fff;
    border-radius: 100px;
    height: 150px;
    position: absolute; 
    top: 100px;
    width: 350px;
    z-index: 0;
}

#right_c{
    background-color: #fff;
    border-radius: 100%;
    height: 150px;
    left: 140px;
    position: absolute; 
    top: 40px; 
    width: 150px;
    z-index: -1;
}

#left_c{
    background-color: #fff;  
    border-radius: 100%;
    height: 100px;
    left: 50px;
    position: absolute; 
    top: 70px; 
    width: 100px;
    z-index: -1;
}

#cloud::before {
    background-color: white;
    border-radius: 50%;
    content: '';
    height: 100px;
    left: 55px;
    position: absolute; 
    top: 75px; 
    width: 100px;
    z-index: 1;
}

#cloud::after {
    position: absolute; top: 45px; left: 145px;
    background-color: white;
    border-radius: 50%;
    content: '';
    width: 150px;
    height: 150px;
    z-index: 1;
}

HTML:

<div id="cloud">
  <div id="bottom_c"></div>
  <div id="right_c"></div>
  <div id="left_c"></div>
</div>

谢谢你的原来的解决方案! 我需要创建多个云和动态调整大小和重新着色他们,所以我适合原来的解决方案如下:

  1. 余由通过使用百分比值的高度,宽度,top和left属性可调整大小的云。 所述.cloud类使用填充顶调整相对于云的宽度云的高度。
  2. 我所做的:before和:after伪元素的div。
  3. 我换了ID选择到类选择
  4. 我重组了属性,使他们更容易阅读。

我希望这可以帮助别人。 下面的代码:

CSS:

.cloud {
    position: relative;
    width: 100%;
    padding-top: 57.5%;
    box-sizing: border-box;
}

.cloud_bottom,
.cloud_left,
.cloud_right {
    border: solid 5px black; 
}

.cloud_bottom,
.cloud_left,
.cloud_right,
.cloud_leftCircle,
.cloud_rightCircle {
    background-color: #fff;
}

.cloud_bottom {
    position: absolute;
    top: 43.48%;
    height: 65.2%;
    width: 87.5%;
    border-radius: 100px;
    z-index: 0;
}

.cloud_left {
    position: absolute;
    top: 30.43%;
    left: 12.5%;
    height: 43.48%;
    width: 25%;
    border-radius: 100%;
    z-index: -1;
}

.cloud_right {
    position: absolute;
    top: 17.39%; 
    left: 35%;
    height: 65.2%;
    width: 37.5%;
    border-radius: 100%;
    z-index: -1;
}

.cloud_leftCircle {
    position: absolute; 
    top: 32.61%;
    left: 13%;
    height: 43.48%;
    width: 25%;
    border-radius: 50%;
    z-index: 1;
}

.cloud_rightCircle {
    position: absolute;
    top: 23.48%;
    left: 35%;
    height: 65.21%;
    width: 37.5%;
    border-radius: 50%;
    z-index: 1;
}

HTML:

<div class="firstCloud cloud">
    <div class="cloud_bottom"></div>
    <div class="cloud_left"></div>
    <div class="cloud_right"></div>
    <div class="cloud_leftCircle"></div>
    <div class="cloud_rightCircle"></div>
</div>

<div class="secondCloud cloud">
    <div class="cloud_bottom"></div>
    <div class="cloud_left"></div>
    <div class="cloud_right"></div>
    <div class="cloud_leftCircle"></div>
    <div class="cloud_rightCircle"></div>
</div>

JavaScript的:

function updateCloudColor(cloudElement, color) {
    cloudElement.children().css("background-color", color);
}

$(window).load(function () {
    updateCloudColor($(".firstCloud"), "red");
    updateCloudColor($(".secondCloud"), "blue");
});
