CSS Tip

A Modern way to create a star shape

Create a Star shape using clip-path and only 5 points instead of 10.

Three different codes to create the same shape

  1. Precise version using math
  2. Calculated version without math
  3. Simplified version with easier coordinates values

CSS-only star shape

/* Accurate version with precise values */
.one {
  aspect-ratio: 1;
  clip-path: polygon(50% 0,
    calc(50%*(1 + sin(.4turn))) calc(50%*(1 - cos(.4turn))),
    calc(50%*(1 - sin(.2turn))) calc(50%*(1 - cos(.2turn))),
    calc(50%*(1 + sin(.2turn))) calc(50%*(1 - cos(.2turn))),
    calc(50%*(1 - sin(.4turn))) calc(50%*(1 - cos(.4turn))) 
   ); 
}
/* A simplified version of the previous one.
   We do the calculation and we round the result */
.two {
  aspect-ratio: 1;
  clip-path: polygon(50% 0,79% 90%,2% 35%,98% 35%,21% 90%); 
}
/* Another simplification with easier clip-path values 
   It covers a bigger area of the element */
.three {
  aspect-ratio: 1.07;
  clip-path: polygon(50% 0,80% 100%,0 39%,100% 39%,20% 100%);
}
