Here is a quick JSFiddle I made with the current setup:

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

}
.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);

width: -webkit-calc(50% - 10px);
width: calc(50% - 10px);

我已经尝试结合使用正&负偏斜可实现此目的，
I've tried using a combination of positive & negative skews to achieve this,
-webkit-transform: skew(20deg);
-moz-transform: skew(20deg);
-o-transform: skew(20deg);
但似乎无法获得所需的布局，有可能吗？
but can't seem to get the desired layout, is it even possible?
推荐答案
诀窍是正确设置transform-orgin，border，然后容易应用两个偏斜变换。您可能还需要一些负余量来纠正某些空格。
The trick is to correctly set the transform-orgin, the border and then it should be easy to apply both skew transformation. You may also need some negative margin to rectify some spaces.
我使用CSS变量来简化代码，但这不是强制性的。
I used CSS variables to make the code easy but it's not mandatory.
#about-gallery {
margin: 60px 0;
display: flex;
flex-wrap: wrap;
--s:-8deg; /* The skew factor (the same for all)*/
}
.about-img-wrapper {
margin: 5px;
overflow: hidden; /* Don't forget this !!*/
flex-grow:1;
}
.about-img-wrapper > * {
height: 300px;
background: center/cover no-repeat;
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;
height:100%;
background:inherit; /* inherit the image */
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)));
}
/**/
.image-1 {
border-left: solid 10px black;
flex-basis:50%;
margin-right:-15px;
}
.image-1>* {
transform-origin: top;
border: solid 10px black;border-left: none;
}
/**/
.image-2 {

flex-basis:40%;

}
/**/

}
.image-5 {
margin-top:-12vw;
}
.image-5>* {
height:calc(300px + 7vw); /* We need a bigger height here */
}
/**/

这里是另一个使用更少的代码并依靠 mask 来创建偏斜效果的想法：
Here is another idea using less of code and relying on mask to create the skew effect:
.about-gallery {
margin: 60px 0;
display: flex;
flex-wrap: wrap;
}
.about-gallery > * {
margin: 5px;
flex-grow:1;
height: 300px;
background:
var(--g),
var(--img) center/cover no-repeat;
border: solid 10px black;
-webkit-mask:
linear-gradient(#fff,#fff) no-repeat,
linear-gradient(to var(--p,bottom right),#fff 49.5%,transparent 50%) no-repeat;
mask:
linear-gradient(#fff,#fff) no-repeat,
linear-gradient(to var(--p,bottom right),#fff 49.5%,transparent 50%) no-repeat;
}
/**/
.image-1 {
flex-basis:50%;
margin-right:-15px;
--g:linear-gradient(to bottom right,transparent 49.8%,black 50%) right/50px 100% no-repeat;
-webkit-mask-position:left,right;
mask-position:left,right;
-webkit-mask-size:calc(100% - 50px) 100%, 50px 100%;
mask-size:calc(100% - 50px) 100%, 50px 100%;
}
/**/
.image-2 {
flex-basis:40%;
margin-left:-15px;
--g:linear-gradient(to top left,transparent 49.8%,black 50%) left/50px 100% no-repeat;
-webkit-mask-position:right,left;
mask-position:right,left;
-webkit-mask-size:calc(100% - 50px) 100%, 50px 100%;
mask-size:calc(100% - 50px) 100%, 50px 100%;
--p:top left;
}
/**/
.image-3 {
flex-basis:100%;
--g:linear-gradient(to bottom right,transparent 49.8%,black 50%) bottom/100% 80px no-repeat;
-webkit-mask-position:top,bottom;
mask-position:top,bottom;
-webkit-mask-size:100% calc(100% - 80px),100% 80px;
mask-size:100% calc(100% - 80px),100% 80px;
}
/**/

--p:top left;
}
.image-5 {
margin-top:-70px;
height:340px;
}
/**/

box-sizing: border-box;
}
<div class="about-gallery">
