你的CSS代码的主要问题是:
你用的高度和宽度不同
你没有旋转正确的角度大小
所以,通过“修复”这些问题,你将生成:
.tear {
显示:inline-block;
变换:旋转(-45度);
边框:5px纯绿色;
宽度:100 px;
身高:100 px;
border-top-left-radius: 50%;
border-bottom-left-radius: 50%;
border-bottom-right-radius: 50%;
}
/***仅用于演示***/
.tear {
保证金:50 px;
}
< div class = "扯" >
< / div >
请注意,为了节省CSS的长度,你可以重写你的border-radius属性:
border-radius: 50% 0 50% 50%;
这可以通过伪元素来增强,如图所示

我在codeen上找到了Vinay Challuru写的。
请注意,根据这里的逻辑,我可以为几乎任何可能的构建形状等创建SVG。例如,一个快速输出是:
<svg viewBox='0 0 400 400'>
<path fill="none" stroke="#333" stroke-width="5" d=" m200,40 C200,115 280,180 280,240 a80,80,0 0,1,120,240 C120,180 200,115 200,40" stroke-linejoin='miter'></path>
< / svg >
它使用SVG,并允许您以多种方式更改形状,能够将其形状更改为所需的结果:
var SVG = function() {
this.element = document.getElementsByTagName("svg")[0];
this.namespace = "http://www.w3.org/2000/svg";
this.width = 400;
this.height = 400;
}
/****Let's initialise our SVG ready to draw our shape****/
var svg = new SVG();
/****This sets up the user interface - we've included the script for this as an external library for the codepen****/
var gui = new dat.GUI();
/****Here's where the code to create the shape begins!****/

CSS版本
虽然这还远远没有完成,但您还可以使用CSS生成这个形状。
.tear{
height:200px;
width:200px;
background: linear-gradient(to bottom, rgba(0,0,0,0) 0%,rgba(0,0,0,0) 29%,rgba(0,0,0,1) 30%,rgba(0,0,0,1) 100%);
border-radius:50%;
margin:120px;
position:relative;
}
.tear:before{
content:"";
position:absolute;
top:-70%;left:0%;
height:100%;width:50%;
background: radial-gradient(ellipse at -50% -50%, rgba(0,0,0,0) 0%,rgba(0,0,0,0) 75%,rgba(0,0,0,1) 76%,rgba(0,0,0,1) 100%);
}
.tear:after{
content:"";
position:absolute;
top:-70%;left:50%;
height:100%;width:50%;
background: radial-gradient(ellipse at 150% -50%, rgba(0,0,0,0) 0%,rgba(0,0,0,0) 75%,rgba(0,0,0,1) 76%,rgba(0,0,0,1) 100%);
}
<div class="tear"></div>
SVG版本
我应该知道SVG应该在这个答案的顶部,但是,我喜欢挑战,所以这里是SVG的一个尝试。
svg {
