如何创建自定义形状 - CSS

Question

我想创建一个像这个图像的自定义形状:

我能怎么做 ？

我的CSS:

#chevron { 
  position: relative;
  text-align: center;
  padding: 12px;
  margin-bottom: 6px;
  height: 60px; 
  width: 200px; }

#chevron:before { 
  content: ''; 
  position: absolute;
  top: 0; 
  left: 0;
  height: 100%;
  width: 51%;
  background: #337AB7;
  -webkit-transform: skew(0deg, 6deg);    -moz-transform: skew(0deg, 6deg);
  -ms-transform: skew(0deg, 6deg);
  -o-transform: skew(0deg, 6deg);
  transform: skew(0deg, 6deg); }

#chevron:after { 
  content: ''; 
  position: absolute;
  top: 0; 
  right: 0;
  height: 100%;
  width: 50%;
  background: #337AB7;
  -webkit-transform: skew(0deg, -6deg); -moz-transform: skew(0deg, -6deg); -ms-transform: skew(0deg, -6deg); -o-transform: skew(0deg, -6deg); transform: skew(0deg, -6deg); }

我的HTML文件:

<div id="chevron">

</div>

但我的结果不是我想要的:

Answer 1

• 将背景颜色添加到父div以填充间隙
• 放置border-radius在父div上以创建两个圆角
• 稍微向下:before和:after向下移动,top: 20px这样它们就不会在div顶部出现峰值

例

这是下面的小提琴:

#chevron {
  width: 350px;
  height: 100px;
  background: #337AB7;
  border-radius: 10px 10px 0 0;
  position: relative;
}
#chevron:before {
  content: '';
  position: absolute;
  top: 20px;
  left: 0;
  height: 100%;
  width: 51%;
  background: #337AB7;
  -webkit-transform: skew(0deg, 6deg);
  -moz-transform: skew(0deg, 6deg);
  -ms-transform: skew(0deg, 6deg);
  -o-transform: skew(0deg, 6deg);
  transform: skew(0deg, 6deg);
}
#chevron:after {
  content: '';
  position: absolute;
  top: 20px;
  right: 0;
  height: 100%;
  width: 50%;
  background: #337AB7;
  -webkit-transform: skew(0deg, -6deg);
  -moz-transform: skew(0deg, -6deg);
  -ms-transform: skew(0deg, -6deg);
  -o-transform: skew(0deg, -6deg);
  transform: skew(0deg, -6deg);
}

<div id="chevron"></div>
