The web has overused standard gray horizontal rule lines. Using an inline flexbox array of CSS polygons, you can build glowing fairy-lights horizontally across your pages!

Flex Alignment and Staggering

.twinkle-string {
  display: flex;
  justify-content: space-around;
  width: 80%;
  margin: 50px auto;
  border-top: 1px solid rgba(253, 224, 71, 0.3); /* The wire */
}

.star {
  width: 10px; height: 10px;
  background: #fde047;
  clip-path: polygon(50% 0%, 61% 35%, 98% 35%, 68% 57%, 79% 91%, 50% 70%, 21% 91%, 32% 57%, 2% 35%, 39% 35%);
  margin-top: -5px; /* Pull it exactly onto the wire line */
  animation: shine 2s infinite alternate;
}

/* De-sync the flashing array natively! */
.star:nth-child(odd)  { animation-delay: 0.5s; }
.star:nth-child(3n)   { animation-delay: 1.2s; }
.star:nth-child(4n)   { animation-delay: 0.2s; }

@keyframes shine {
