Creates a triangular shape with pure CSS.

• Use three borders to create a triangle shape.
• All borders should have the same border-width (20px).
• The opposite side of where the triangle points towards (i.e. top if the triangle points downwards) should have the desired border-color, whereas the adjacent borders (i.e. left and right) should have a border-color of transparent.
• Altering the border-width values will change the proportions of the triangle.

<div class="triangle"></div>

  height: 0;
  border-top: 20px solid #9C27B0;
