How CSS Triangles Work

CSS triangles are created using border tricks. By making an element with zero width/height and manipulating its borders, you can create triangle shapes. This technique is useful for:

  • Tooltips and popovers
  • Dropdown indicators
  • Speech bubbles
  • Arrow icons
  • Decorative elements

Tip: The triangle adjusts in real-time as you change the settings.
