Crafting a Transparent Triangle with Border Using CSS

Creating complex shapes with CSS can be challenging, but when it comes to triangles, there are various approaches to achieve your desired effect.

One method, which you've experimented with, involves utilizing borders. While this technique works, it relies on visual tricks. Is there a more elegant solution?

Yes, there is! A webkit-exclusive approach involves leveraging the Unicode character U 25B6 (▲). Here's how:

.triangle {
  -webkit-text-stroke: 12px black;
  color: transparent;
  font-size: 200px;
}

▲

This code leverages the text stroke property to outline the character as a triangle. The color transparency allows the interior to remain empty, while the font size controls the size of the shape.

While this solution is specific to webkit browsers, it provides a concise and visually striking way to render a transparent triangle with border.
