🧐 Frequently Asked Questions


How does the "border method" work?
By setting an element's dimensions to zero and applying thick borders with one side colored and the others transparent, the diagonal meeting points of the borders form a perfect triangle.


Can I make these triangles responsive?
Yes. While the generator outputs px by default, you can manually swap those units for rem, em, or vw in your code for fluid scaling.


Is this compatible with modern frameworks?
Absolutely. The output is standard CSS that works in vanilla projects, React, Vue, Tailwind config files, or any CSS-in-JS library.


💡 Pro Tip


While modern properties like clip-path can also create shapes, the border method remains the industry standard for UI "tails" and tooltips because it requires zero dependencies and offers the broadest browser support.
