How to create a transparent triangle with border using CSS?

How can I create the following shape with CSS?

Enter image description here

I tried this to be a solution:

.triangle:after {
  position: absolute;
  content: "";
  width: 0;
  height: 0;
  margin-top: 1px;
  margin-left: 2px;
  border-left: 10px solid transparent;
  border-right: 10px solid transparent;
  border-bottom: 10px solid white;
}

.triangle:before {
  position: absolute;
  content: "";
  width: 0;
  height: 0;
  border-left: 12px solid transparent;
  border-right: 12px solid transparent;
  border-bottom: 12px solid black;
}
<div class="triangle"></div>

You can see it working at Triangle. This is working, but with a trick of borders. Is there another way it could be done?

Using SVG vectors this can be done easily, but I don't want to go that lengthy way.

Solution

  • I've found a webkit-only solution, using the ▲ character:

    .triangle {
  -webkit-text-stroke: 12px black;
  color: transparent;
  font-size: 200px;
}
    <div class="triangle">&#9650;</div>
