Divide div with diagonal line

Question

How would you divide a div into 2 parts (both containing horizontal text) along a diagonal line?

eg. see this where 1 has a rectangular background image and 2 has text with background color:

Answer 1

You can do this with a pseudo-element rotating as follows:

body {
  background-color: #00bcd4;
}
.main {
  margin: 50px;
  overflow: hidden;
  position: relative;
  width: 350px;
}
.image {
  background: url(https://s-media-cache-ak0.pinimg.com/564x/ca/9b/ca/ca9bca4db9afb09158b76641ea09ddb6.jpg) center center no-repeat;
  background-size: cover;
  height: 200px;
}
.text {
  background-color: white;
  padding: 30px;
  position: relative;
}
.text > div {
  position: relative;
  z-index: 1;
}
.text:before {
  content: "";
  background-color: white;
  position: absolute;
  height: 100%;
  width: 120%;
  top: -20px;
  left: -10%;
  transform: rotate(5deg);
  z-index: 0;
}

<div class="main">
  <div class="image"></div>
  <div class="text">
    <div>
      Lorem ipsum dolor sit amet, consectetur adipiscing elit. Praesent vitae gravida purus. Ut quis elit magna. Fusce et mattis sapien. Sed venenatis magna ut ligula facilisis, eget vulputate neque aliquet. Nulla lacinia condimentum leo non aliquet. Integer
      et enim dapibus, tempor ipsum non, fringilla enim. Cras semper fermentum dolor, at pharetra dolor ornare sit amet. Morbi eu dictum orci, tincidunt pretium nisi. Sed finibus vulputate eleifend. Nulla ac leo facilisis, fermentum tellus in, feugiat
      risus. Curabitur in sem luctus, pellentesque justo nec, aliquet velit. Nam euismod est sit amet ultrices consequat.
    </div>

Answer 2

As I know, it cannot be executed using any one CSS property directly, you will have to hack it using pseudo elements, or the best approach would be to do it using SVG

.container {
  width: 90%;
  margin: 0 auto;
}
.box {
  width: 200px;
  height: 150px;
  text-align: center;
}
.box-1 {
  background: #ff6347;
}
.box-2 {
  background: #0ff;
}
.box-2:before {
  display: inline-block;
  margin: 0;
  margin-top: -30px;
  margin-left: -30px;
  content: '';
  border: 30px solid transparent;
  border-right: 200px solid #0ff;
}

<div class="container">
    <div class="box box-1"></div>
    <div class="box box-2">
      TITLE 1
    </div>
</div>

Answer 3

.container {
  width: 400px;
  margin: 0 auto;
}
.box {
  width: 200px;
  height: 150px;
  text-align: center;
  float: left;
}
.box-1 {
  background: #ff4500;
}
.box-2 {
  background: #0ffab9;
}
.box-2:before {
  display: inline-block;
  margin: 0;
  margin-left: -101px;
  margin-top: -1px;
  position: absolute;
  content: '';
  width: 0;
	height: 0;
	border-bottom: 151px solid #0ffab9;
	border-left: 30px solid transparent;
}

<div class="container">
    <div class="box box-1">
    </div>
    <div class="box box-2">
      TITLE 1
    </div>
</div>
