我基本上要创建的布局如下:

下面是我用当前设置制作的一个快速JSFiddle:

#about-gallery {
  margin: 60px 0;
  display: -ms-flex;
  display: -webkit-flex;
  display: flex;
  flex-wrap: wrap;
  margin-bottom: 500px;
  width: 100%;
}

.about-img-wrapper {
  position: relative;
  width: 100%;
  display: -ms-flex;
  display: -webkit-flex;
  display: flex;
  flex-wrap: wrap;
  margin: 5px;
}

#about-gallery .about-bg {
  border: solid 10px black;
  float: left;
  width: 100%;
  height: 300px;
  background-size: cover;
  background-position: center;
}

#about-gallery .image-1 {
  width: -moz-calc(55% - 10px);
  width: -webkit-calc(55% - 10px);
  width: calc(55% - 10px);
}

#about-gallery .image-2 {
  width: -moz-calc(45% - 10px);
  width: -webkit-calc(45% - 10px);
  width: calc(45% - 10px);
}

#about-gallery .image-4,
#about-gallery .image-5 {
  width: -moz-calc(50% - 10px);
  width: -webkit-calc(50% - 10px);
  width: calc(50% - 10px);
}

<div id="about-gallery">
  <div class="about-img-wrapper img-about image-1">
    <div class="about-bg" style="background-image: url(https://via.placeholder.com/1140x400.png?text=SKEW+THIS+IMAGE+ON+ONE+SIDE);"></div>
  </div>
  <div class="about-img-wrapper img-about image-2">
    <div class="about-bg" style="background-image: url(https://via.placeholder.com/1140x400.png?text=SKEW+THIS+IMAGE+ON+ONE+SIDE);"></div>
  </div>
  <div class="about-img-wrapper img-about image-3">
    <div class="about-bg" style="background-image: url(https://via.placeholder.com/1140x400.png?text=SKEW+THIS+IMAGE+ON+ONE+SIDE);"></div>
  </div>
  <div class="about-img-wrapper img-about image-4">
    <div class="about-bg" style="background-image: url(https://via.placeholder.com/1140x400.png?text=SKEW+THIS+IMAGE+ON+ONE+SIDE);"></div>
  </div>
  <div class="about-img-wrapper img-about image-5">
    <div class="about-bg" style="background-image: url(https://via.placeholder.com/1140x400.png?text=SKEW+THIS+IMAGE+ON+ONE+SIDE);"></div>
  </div>

</div>

我试着用正反两方面的结合来达到这个目的,

-webkit-transform: skew(20deg);
   -moz-transform: skew(20deg);
     -o-transform: skew(20deg);

诀窍是正确地设置变换orgin、边界,然后应该很容易地应用这两个歪斜变换。您可能还需要一些负边距来校正一些空间。

我使用CSS变量来简化代码,但这不是强制性的。

#about-gallery {
  margin: 60px 0;
  display: flex;
  flex-wrap: wrap;
  --s:-8deg; /* The skew factor (the same for all)*/
}

.about-img-wrapper {
  position: relative;
  margin: 5px;
  overflow: hidden; /* Don't forget this !!*/
  flex-grow:1;
}

.about-img-wrapper > * {
  height: 300px;
  background-size: 0 0; /* Hide the image here */
  background-position: center;
  overflow: hidden; /* Don't forget this !!*/
  transform:skewX(var(--s,0deg));
}
/* We need skewY for the 3 last element */
.about-img-wrapper:nth-child(n + 3) > *  {
  transform:skewY(var(--s,0deg));
}
/* The pseudo element will get the image and the inverse of skewing */
.about-img-wrapper > *::before {
  content:"";
  display:block;
  width:100%;
  height:100%;
  background:inherit; /* inherit the inline image */
  background-size:cover; 
  transform-origin: inherit; /* inherit the same transform-origin */
  transform:skewX(calc(-1*var(--s,0deg)));
}
.about-img-wrapper:nth-child(n + 3) > *::before  {
  transform:skewY(calc(-1*var(--s,0deg)));
}
