two divs split with diagonal line - CSS

Question

I am trying to get two divs to fit the full width of the page but split in half with a diagonal line.

How can I achieve this with two divs through CSS? it is for a slider and needs content added to each part when finished

What did you try so far? – Dominick

You should have a look at this answer. Using a combination of the examples where there is a slant on the left side and on the right side, you can achieve what you need. Please try and update the question if you get stuck while doing. – Ashwell

It can be something like this

Example 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>

Great answer. I was just doing something similar. If you do all values in em it auto-adjusts to font size - My Demo – Nippur

Thanks for this. Did not actually use the way you did but helped get a rough idea – Princessprinceton

<div class="container">
  <div class="left"><span>left</span></div>
  <div class="right"><span>right</span></div>
</div>

.container {
  display: flex;
  flex-direction: row;
  color: white;
  font-family: system-ui;
  font-size: 2rem;
  overflow: hidden;
  margin: 0 auto;
}

.left,
.right {
  width: 50%;
  height: 400px;
  display: flex;
  justify-content: center;
  align-items: center;
}

.left {
  position: relative;
}

.left::after {
  content: "";
  position: absolute;
  background: blue;
  top: 0;
  bottom: 0;
  right: 0;
  width: 100vw;
  transform: skew(-25deg);
  z-index: 10;
}

.right {
  position: relative;
  text-align: right;
}

.right::before {
  content: "";
  position: absolute;
  background: red;
  top: 0;
  bottom: 0;
  left: 0;
  width: 100vw;
  transform: skew(-25deg);
  z-index: 10;
}

span {
  z-index: 20;
}
