取消倾斜分类多个倾斜图像的末端

Question

我之前问过这个question，询问如何扭曲各种图像。我能够得到非常令人满意的结果

.container {
  font-size: 0;
  height: 215px;
  margin: 30px 50px;
  text-align: center;
  color: black;
}

.box1 {
  font-size: initial;
  width: calc(100% / 6);
  height: 100%;
  border: 3px solid;
  box-sizing: border-box;
  transform: skew(-25deg);
  position: relative;
  overflow: hidden;
  display: inline-block;
}

.box2 {
  font-size: initial;
  width: calc(100% / 6);
  height: 100%;
  border: 2.5px solid;
  box-sizing: border-box;
  transform: skew(-25deg);
  position: relative;
  overflow: hidden;
  display: inline-block;
}

.box3 {
  font-size: initial;
  width: calc(100% / 6);
  height: 100%;
  border: 2.5px solid;
  box-sizing: border-box;
  transform: skew(-25deg);
  position: relative;
  overflow: hidden;
  display: inline-block;
}

.box4 {
  font-size: initial;
  width: calc(100% / 6);
  height: 100%;
  border: 2.5px solid;
  box-sizing: border-box;
  transform: skew(-25deg);
  position: relative;
  overflow: hidden;
  display: inline-block;
}

.box5 {
  font-size: initial;
  width: calc(100% / 6);
  height: 100%;
  border: 2.5px solid;
  box-sizing: border-box;
  transform: skew(-25deg);
  position: relative;
  overflow: hidden;
  display: inline-block;
}

.box6 {
  font-size: initial;
  width: calc(100% / 6);
  height: 100%;
  border: 2.5px solid;
  box-sizing: border-box;
  transform: skew(-25deg);
  position: relative;
  overflow: hidden;
  display: inline-block;
}

.box1 span {
  position: absolute;
  top: 0;
  bottom: 0;
  left: -100%;
  right: -100%;
  transform: skew(25deg);
  background-position: center;
  background-size: cover;
}

.box2 span {
  position: absolute;
  top: 0;
  bottom: 0;
  left: -50%;
  right: -50%;
  transform: skew(25deg);
  background-position: center;
  background-size: cover;
}

.box3 span {
  position: absolute;
  top: 0;
  bottom: 0;
  left: -50%;
  right: -50%;
  transform: skew(25deg);
  background-position: center;
  background-size: cover;
}

.box4 span {
  position: absolute;
  top: 0;
  bottom: 0;
  left: -35%;
  right: -35%;
  transform: skew(25deg);
  background-position: center;
  background-size: cover;
}

.box5 span {
  position: absolute;
  top: 0;
  bottom: 0;
  left: -50%;
  right: -50%;
  transform: skew(25deg);
  background-position: center;
  background-size: cover;
}

.box6 span {
  position: absolute;
  top: 0;
  bottom: 0;
  left: -35%;
  right: -35%;
  transform: skew(25deg);
  background-position: center;
  background-size: cover;
}

<div class="container">
  <div class="box1"><span style="background-image:url(illustris1.png)"></span></div>
  <div class="box2"><span style="background-image:url(gal.png)"></span></div>
  <div class="box3"><span style="background-image:url(laniakea.jpg)"></span> </div>
  <div class="box4"><span style="background-image:url(globularstar.jpg)"></span></div>
  <div class="box5"><span style="background-image:url(elliptical.jpg)"></span></div>
  <div class="box6"><span style="background-image:url(illustris2.png)"></span></div>
  <div class="container mid"></div>
</div>

虽然我的这段代码与来自另一个线程的回答相比很长，但它允许我为我输入的每张图片调整大小。

我现在要做的是让这个container 环境的最左端box1 和最右端box6 只在这个分类的内部偏斜。这有点像这张海报想要得到的结果：Skew one side only of an element。

几个小时以来，我一直在尝试几种方法，但我似乎没有运气改变 box1 和 box6 在不扭曲图像的情况下使一侧倾斜。

您可以对最后一个和第一个使用负边距来隐藏一半元素：

.container {
  display: flex;
  height: 150px;
  margin: 0 30px;
  overflow:hidden;
}

.box {
  flex: 1;
  border: 1px solid;
  transform: skew(-25deg);
  position: relative;
  overflow: hidden;
}
.box:first-child {
  margin-left:calc((100% / 5) / -2);
}
.box:last-child {
  margin-right:calc((100% / 5) / -2);
}

.box:after {
  content: "";
  position: absolute;
  top: 0;
  bottom: 0;
  left: -50%;
  right: -50%;
  transform: skew(25deg);
  background-image: var(--i);
  background-position: center;
}
