html - 如何在css中使六边形变长

Question

我已阅读 this回答，但我正在使用 here 中的以下代码制作六边形。虽然六边形 react 灵敏，但无法使其拉长。我不太喜欢使用边框解决方案，而是想添加类来覆盖现有样式。

.socialIcon {
    width: 100px;
    height: 100px;
    color: black;
    transition: color 400ms ease-in;
}
.color {
    background-color: #1ae694;
    transition: background-color 500ms ease-in;
}
.hexagonWrapper {
    text-align: center;
    position: relative;
    display: inline-block;
    margin: 50px;
}
.iconContainer {
    position: absolute;
    display: flex;
    align-items: center;
    justify-content: center;
    top: 0;
    bottom: 0;
    left: 0;
    right: 0;
}
.hexagon {
    height: 100%;
    width: calc(100% * 0.57735);
    display: inline-block;
}
.hexagon:before {
    position: absolute;
    top: 0;
    right: calc((100% / 2) - ((100% * 0.57735) / 2));
    background-color: inherit;
    height: inherit;
    width: inherit;
    content: "";
    transform: rotateZ(60deg);
}
.hexagon:after {
    position: absolute;
    top: 0;
    right: calc((100% / 2) - ((100% * 0.57735) / 2));
    background-color: inherit;
    height: inherit;
    width: inherit;
    content: "";
    transform: rotateZ(-60deg);
}

<a class="socialIcon hexagonWrapper" href="#" target="_blank">
  <div class="color hexagon"></div>
  <div class="iconContainer">
    <span>H</span>
  </div>
</a>

我建议您使用来自 answer 的 Temani 方法.
它使用多个 linear-gradient 来创建背景，并且在 HTML 中需要更少的元素:

.socialIcon {
  color: black;
  transition: color 400ms ease-in;
}

.color {
  --color: #1ae694;
  background-color: var(--color);
}

.hexagonWrapper {
  text-align: center;
  position: relative;
  display: inline-block;
}

.hexagon {
  padding: 10px 60px;
  display: inline-block;

  background:
   linear-gradient(to top right,    var(--color) 49.5%, transparent 50.5%) top right    / 20px 50%,
   linear-gradient(to bottom right, var(--color) 49.5%, transparent 50.5%) bottom right / 20px 50%,
   linear-gradient(to bottom left,  var(--color) 49.5%, transparent 50.5%) bottom left  / 20px 50%,
   linear-gradient(to top left,     var(--color) 49.5%, transparent 50.5%) top left     / 20px 50%,
   linear-gradient(var(--color), var(--color)) center / calc(100% - 40px) 100%;
  background-repeat:no-repeat;
}

/* Added after comment */
.hexagon:hover {
  --color: #aae;
}

<a class="socialIcon hexagonWrapper" href="#" target="_blank">
  <div class="color hexagon"><p>xxx</p></div>
</a>

旧答案

由于拉长的六边形不再是六边形，我建议您使用一种完全不同的方法来实现这一目标，使用:

• height 和 color 的 CSS 变量，
伪元素上的
• border 以创建“三 Angular 形”形状。

这是一个片段:

.socialIcon {
  --color: #1ae694; /* CSS Variable */
  --h: 100px; /* CSS Variable */
  width: 100px;
  height: var(--h); /* Using CSS var */
  color: black;
  transition: color 200ms ease-in;
}

.socialIcon:hover {
  --color: #aae;
}

.color {
  background-color: var(--color); /* Using CSS var */
  transition: background-color 500ms ease-in;
}

.hexagonWrapper {
  text-align: center;
  position: relative;
  display: inline-block;
  margin: 50px;
}

.iconContainer {
  position: absolute;
  display: flex;
  align-items: center;
  justify-content: center;
  top: 0;
  bottom: 0;
  left: 0;
  right: 0;
}

.hexagon {
  height: 100%;
  width: 100%;
  display: inline-block;
}

/* TAKIT: I changed everything below */

.hexagon::before,
.hexagon::after {
  position: absolute;
  height: 0;
  width: 0;
  content: "";
  border: 0 solid transparent;
  /* border is full height but half width, to render a thin arrow shape
  This can be parameterized here: */
  border-width: calc(var(--h)/2) calc(var(--h)/4); /* Using CSS var */
  transition:
    border-left-color 500ms ease-in,
    border-right-color 500ms ease-in;
}

.hexagon::before {
  left: 0;
  transform: translate(-100%, 0);
  border-right-color: var(--color); /* Using CSS var */
}

.hexagon::after {
  right: 0;
  transform: translate(100%, 0);
  border-left-color: var(--color); /* Using CSS var */
}

<a class="socialIcon hexagonWrapper" href="#" target="_blank">
  <div class="color hexagon"></div>
  <div class="iconContainer">
    <span>H</span>
  </div>
</a>

使用该解决方案，唯一需要调整的是 var: --h 以获得实际的六边形或拉长的六边形......
