Creates a triangle shape with pure CSS.
<div class="triangle"></div>
.triangle {
width: 0;
height: 0;
border-top: 20px solid #333;
border-left: 20px solid transparent;
border-right: 20px solid transparent;
}
View this link for a detailed explanation.
The color of the border is the color of the triangle. The side the triangle tip points
corresponds to the opposite border-*
property. For example, a color on border-top
means the arrow points downward.
Experiment with the px
values to change the proportion of the triangle.
✅ No caveats.
