How to Create Transparent Triangles with Visible Borders in CSS: Beyond WebKit's Text-Stroke?

Alternative to Using Borders for Transparent Triangles with CSS

In pursuit of creating a transparent triangle with a visible border, one may encounter limitations using the traditional approach with pseudo-elements and borders. This path involves the use of the Unicode character ▲ and the CSS text-stroke property, which is exclusive to WebKit browsers.

To implement this technique:

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

<code class="html"><div class="triangle">▲</div></code>

The ▲ character represents a symmetrical triangle, and the text-stroke property defines the width and color of its border. The transparent color of the text ensures that the triangle itself remains invisible, allowing only its border to be visible.

While this method provides a solution unique to WebKit browsers, it's worth noting its limited compatibility. For broader support, consider exploring alternative approaches such as SVG vectors or CSS transforms.
