Question

您是否知道如何实现（仅使用CSS，画布等）这种具有不规则形状的Circle菜单？ PS。 IE和旧浏览器 - 我不在乎

Answer 1

＆＃34;圈＆＃34;在以下示例中， 与图像完全相同形状。这是可能的，但至少以下内容将帮助您入门。

＆＃13;

＆＃13;

UL.circle-menu {
  list-style: none;
  padding: 0;
}

UL.circle-menu LI {
  display: block;
  float: left;
  width: 115px;
  text-align: center;

Answer 2

我认为实现这一目标的最佳方法是使用SVG过滤器。你在谈论已经存在的效果，它被称为Goo。

＆＃13;

＆＃13;

.menu{
  filter:url('#shadowed-goo');
  position:absolute;
  left:0;
  padding-top:20px;
  padding-left:50px;
  width:100px;
  height:100px;
  box-sizing:border-box;
  font-size:20px;
  text-align:left;
}
.menu-item{
  border-radius:100%;
  width:80px;
  height:80px;
  position:absolute;
  top:20px;
  text-align:center;
  line-height:80px;
  background:#f62;
  left:10px;
}
.home{
  width:100px;
  position:absolute;
  text-align:center;
  top:113px;
  left:0;
  background:#f62;
  height:100px;
}

＆＃13;

<nav class="menu">
  <a href="#" class="menu-item"></a>
  <div class="home">home</div>
</nav>


<!-- filters -->
<svg xmlns="http://www.w3.org/2000/svg" version="1.1">
    <defs>
      <filter id="shadowed-goo">
          
          <feGaussianBlur in="SourceGraphic" result="blur" stdDeviation="10" />
          <feColorMatrix in="blur" mode="matrix" values="1 0 0 0 0  0 1 0 0 0  0 0 1 0 0  0 0 0 18 -7" result="goo" />
          <feGaussianBlur in="goo" stdDeviation="3" result="shadow" />
          <feColorMatrix in="shadow" mode="matrix" values="0 0 0 0 0  0 0 0 0 0  0 0 0 0 0  0 0 0 1 -0.2" result="shadow" />
          <feOffset in="shadow" dx="1" dy="1" result="shadow" />
          <feBlend in2="shadow" in="goo" result="goo" />
          <feBlend in2="goo" in="SourceGraphic" result="mix" />
      </filter>
      <filter id="goo">
          <feGaussianBlur in="SourceGraphic" result="blur" stdDeviation="10" />
          <feColorMatrix in="blur" mode="matrix" values="1 0 0 0 0  0 1 0 0 0  0 0 1 0 0  0 0 0 18 -7" result="goo" />
          <feBlend in2="goo" in="SourceGraphic" result="mix" />
      </filter>
    </defs>
</svg>
