Create star shapes using polygon with alternating outer and inner points. Learn the geometry of star shapes.
clip-path: polygon(50% 0%, 61% 35%, 98% 35%, 68% 57%, 79% 91%, 50% 70%, 21% 91%, 32% 57%, 2% 35%, 39% 35%);
/* 5-pointed star requires 10 points */
/* Alternates between outer and inner points
