有没有办法在CSS/HTML/JS中以三角形/金字塔的方式生成六角形？

<div class="hexagon"></div>

.hexagon {
  width: 100px;
  height: 55px;
  background-color: #ff0000;
  position: relative;
}

.hexagon::before,
.hexagon::after {
  content: "";
  position: absolute;
  width: 0;
  border-left: 50px solid transparent;
  border-right: 50px solid transparent;
}

.hexagon::before {
  bottom: 100%;
  border-bottom: 27.5px solid #ff0000;
}

.hexagon::after {
  top: 100%;
  width: 0;
  border-top: 27.5px solid #ff0000;
}
