您可以使用:before和:after伪元素来实现此目的。

您可以拥有容器元素<div class="image-container image-container-col-2">和多个子<div class="image-container-split">。

添加了

.image-container-col-2以标记容器将被拆分为两个。因此，该解决方案可适用于更多列。或者甚至更多，使用像Bootstrap自己的列系统这样的现有CSS库并对其进行调整。

以下代码很长，如果您使用SCSS，您可以轻松地对其进行参数化以便更具可读性。

解决方案1：多列但不在主容器上的内容

＆＃13;
＆＃13; 
p {
  font-size: 1.1em;
  font-family: Arial;
  color: #fff;
}

.image-container {
  position: relative;
  width: 500px;
  height: 331px;
}

.image-container.image-container-col-2 .image-container-split {
  width: 50%;
}

.image-container:before {
  content: '';
  position: absolute;
  z-index: -2;
  top: 0;
  left: 0;
  right: 0;
  bottom: 0;
  background-image: url(http://az616578.vo.msecnd.net/files/2016/04/09/6359580807140768861266757027_Never-Study-Hard-The-Art-of-Studying-Smart.jpg);
  background-repeat: none;
  background-size: cover;
}

.image-container-split {
  position: relative;
  height: 100%;
  float: left;
  box-sizing: border-box;
  border: 20px solid transparent;
  border-bottom-color: #fff;
  
  text-align: center;
  
  /* Flexbox - use this to align items inside your container */
  display: flex;
  justify-content: center;
  align-items: center;
  flex-flow: wrap column;
}

.image-container-split:first-child {
  border-left: none;
}

.image-container-split:last-child {
  border-right: none;
}

.image-container-split:nth-child(odd) {
  padding-left: 20px;
}

.image-container-split:nth-child(even) {
  padding-right: 20px;
}

.image-container-split:after {
  content: '';
  position: absolute;
  top: -20px;
  border: 10px solid #fff;
  border-bottom-color: transparent;
}

.image-container-split:nth-child(odd):after {
  right: -20px;
  border-left-color: transparent;
}

.image-container-split:nth-child(even):after {
  left: -20px;
  border-right-color: transparent;
}

.image-container-split:before {
  content: '';
  position: absolute;
  z-index: -1;
  top: -20px;
  right: 0;
  left: 0;
  bottom: -20px;
  border: 20px solid transparent;
  border-bottom-color: #fff;
  opacity: 0.5;
}

.image-container-split:first-child:before {
  border-left: none;
}

.image-container-split:last-child:before {
  border-right: none;
}

.image-container-split:nth-child(odd):before {
  background-color: red;
  right: -20px;
}

.image-container-split:nth-child(even):before {
  background-color: blue;
  left: -20px;
}
＆＃13;

＆＃13;

解决方案2：多个列以及主容器上的内容

内容放在主容器上和单独的两列上（注意表情符号）。

＆＃13;
＆＃13; 
p {
  font-size: 1.1em;
  font-family: Arial;
  color: #fff;
}

.image-container-split p {

  flex-flow: wrap column;
  align-items: center;
  justify-content: center;
}

.image-container.image-container-col-2 .image-container-split:nth-child(odd) {
  left: 0;
  right: 50%;
}

.image-container.image-container-col-2 .image-container-split:nth-child(even) {

  background-repeat: none;
  background-size: cover;
}

.image-container-split {
  position: absolute;
  z-index: -3;
  top: 0;
  bottom: 0;
  box-sizing: border-box;
  border: 20px solid transparent;
  border-bottom-color: #fff;
  padding-bottom: 20px;
  
  /* Flexbox - use this to align content */
  display: flex;
  flex-direction: wrap column;
  align-items: center;
  justify-content: center;
}

.image-container-split:first-child {
  border-left: none;
  padding-left: 20px;
}

.image-container-split:last-child {
  border-right: none;
  padding-right: 20px;
}

.image-container-split:before {

}

仅包含三角形的容器

如果需要包含某些三角形的容器，则可以实现以下目标：

图片的尺寸为500 x 331。

:before - 正在创建顶部三角形

:after +背景图片 - 正在创建底部三角形

.image-container的高度比图片小，以便将剩余部分添加到底部三角形

＆＃13;
＆＃13; 
p {
  font-size: 1.1em;
  font-family: Arial;
  color: #fff;
}

.image-container-split p {
  font-size: 3em;
}


.image-container {
  position: relative;
  width: 500px;
  height: 311px;
  padding: 20px;

  text-align: center;

}

.image-container:before {

  border-top-color: #fff;
}

.image-container:after {

答案 1 :(得分：0)

只需进行一些更改，即可完成目标：

.anchor_top {
    width: 0;
    height: 0;
    border-left: 15px solid transparent;
    border-right: 15px solid transparent;
    border-top: 10px solid white;
    position: absolute;
    left: 48.9%; //change here
    top: 0px;
    z-index: 1;
}

对于底部： 

.anchor_bottom_left {
    width: 0;
    height: 0;
    border-left: 15px solid transparent;
    border-top: 10px solid grey;
    position: absolute;
    left: 48.9%; //change here
    z-index: 1;
}

.anchor_bottom_right {
    width: 0;
    height: 0;
    border-right: 15px solid transparent;
    border-top: 10px solid #d98d8e;
    position: absolute;
    left: 50%; //change here and remove border-left
    z-index: 1;
}

答案 2 :(得分：0)

一种选择是使用pseudo-classes + transform:skewX。 

/* Using pseudo-classes + transform skewX */

.products_box:before,
.products_box:after {
  content: '';
  display: block;
  width: 50%;
  position: absolute;
  bottom: 0;
  height: 15px;
  background: white;
  transform: skewX(50deg);
  z-index: 2;
}

.products_box:before {
  left: -10px;
}

.products_box:after {
  right: -10px;
  transform: skewX(-50deg);
}
