Create an Angled Color Banner

Question

Hi I'm trying to create the following Angled Strip Look in HTML & CSS:

Just the Blue and Purple area with white after.

I can obviously see how to do it using an image but what about HTML/CSS only?

Is this possible?

Its used on the site - www.africa.dating

I know I should have more example code but I'm actually not sure where to begin so I only have the following HTML:

Fiddle: http://jsfiddle.net/e2dr5udr/3/

<div id="container">
    <div id="blue"></div>
    <div id="purple"></div>
</div>

#container {
    width: 100%;
    height: 100px;
    background-color: white;
    position: absolute;
}

#blue {
    width: 100%;
    height: 100px;
    background-color: blue;
    position: absolute;
} 

#purple {
    width: 100%;
    height: 100px;
    background-color: purple;
    position: absolute;
}

thankyou

You can use a pseudo element and some border manipulation.

This would allow you to create it with only a single element, to create this:

.title {
  height: 1px;
  background-color: transparent;
  border-bottom: 170px solid blue;
  border-right: 170px solid transparent;
  width: 190px;
  position:relative; 
}

.title:after{
  content:"";
  position:absolute;
  height: 1px;
  top:0px;
  background-color: transparent;
  border-bottom: 170px solid purple;
  border-right: 170px solid transparent;
  width: 210px;
  z-index:-1;
  }

<div class="title"></div>

If you do not want to use this approach, an alternative method (using background gradients) can be viewed here

Using SkewX:

div{
  position:relative;
  height:15vh;
  width:60vw;
  overflow:hidden;
  }
div:before{
  z-index:-1;
  content:"";
  position:absolute;
  top:0;
  height:100%;
  right:50%;
  width:150%;
  border-right:10px solid green;
  background:cornflowerblue;
  -webkit-transform:skewX(45deg);
  transform:skewX(45deg);
  }

<div>123</div>
