两个divs用对角线分割 - CSS

Question

我想让两个div适合整个页面的宽度，但用一条对角线分成两半。

我如何通过CSS来实现这一点？ 这是一个滑块，需要在完成后为每个部分添加内容。

Answer 1

可以是这样的

例1

div {
    min-height: 100px;
    background: #D25A1E;
    position: relative;
    width: calc(50% - 30px);
}
.div1 {
    float: left;
}
.div2 {
    float: right;
}
.div1:after, .div2:before {
    content:'';
    position: absolute;
    top: 0;
    width: 0;
    height: 0;
}
.div1:after {
    left: 100%;
    border-top: 100px solid #D25A1E;
    border-right: 50px solid transparent;
}
.div2:before {
    right: 100%;
    border-bottom: 100px solid #D25A1E;
    border-left: 50px solid transparent;
}

<div class="div1"></div>
<div class="div2"></div>

例二

div {  
    background: #D25A1E;
    min-height: 100px;
    width: calc(50% - 25px);
    position: relative;     
}
.div1 {
    float: left;
}
.div2 {
    float: right;
}
div:after {
    position: absolute; top: 0px;
    content:'';    
    z-index: -1;
    height: 100%;
    width: 50%;
    background: #D25A1E;
}
.div1:after {    
    right: 0;
    transform-origin: bottom right;
    transform: skewX(-20deg);
}
.div2:after {    
    left: 0;
    transform-origin: top left;
    transform: skewX(-20deg);
}

<div class="div1"></div>
<div class="div2"></div>

例三

* {
  padding: 0;
  margin: 0;
  box-sizing: border-box;
}

.blocks {
  display: flex;
  padding: 1em;
}

.block {
  background-color: #D25A1E;
  min-height: 100px;
  width: 50%;
  width: calc(50% + 2rem);
}

.block--left {
  clip-path: polygon(0 0, 100% 0, calc(100% - 3rem) 100%, 0% 100%);
}

.block--right {
  margin-left: -2rem;
  clip-path: polygon(3rem 0, 100% 0, 100% 100%, 0% 100%);
}

<div class="blocks">
  <div class="block block--left"></div>
  <div class="block block--right"></div>
</div>
