我一直在绞尽脑汁想如何使用The Code Player's CSS3 Squircles example在我的网站上创建一个iOS-7风格的应用程序图标（在Safari浏览器中测试）。这个例子使用伪标签来裁剪背景色，而我需要裁剪一个<img>。如果你不熟悉，squircle就像一个圆角矩形，但是侧面倒圆超过拐角半径，像这样：

.icons img {
  width: 100px;
  height: 100px;

  border-radius: 24%;
}

.icons a {
  text-decoration: none;
  display: inline-block;
  position: relative;
}
/*Now we will create fish-eye shapes using pseudo elements and clip them to add a curve to the sides of the icons*/
.icons a:before, .icons a:after {
  content: '';
  position: absolute; left: 0; top: 0;
  width: 100%; height: 100%;
  background: inherit;
  border-radius: 100%; /*circle*/
  /*time to transform the circle into fish-eye shape. iOS7 style now.*/
  -webkit-transform: scaleX(2) scaleY(1.05);
  transform: scaleX(2) scaleY(1.05);
  /*clipping the left and right sides - 17px from the left and right*/
  clip: rect(0, 66px, 100px, 34px);
  /*pushing it behind the icon*/
  z-index: -1;
}
/*duplicating the :before element and rotating it 90deg and swapping the X/Y transforms*/
.icons a:after {
  -webkit-transform: scaleY(2) scaleX(1.05) rotate(90deg);
}

<div class="icons">
  <a href="#"><img src="http://lorempixel.com/256/256/abstract/2/" /></a>
</div>

最简单的解决方案可能是创建具有透明背景的图像，直到实现以下某些功能。
如果你可以通过CSS添加图像，那么你可以只添加高度，宽度，背景图像和背景大小的链接（.icons a）。

- 注：**这可能不是所需的效果，因为它是由背景颜色补充的。

.icons a {
      height: 100px;
      width: 100px;
      background-image: url(https://picsum.photos/256/);
      background-size: cover;
      text-decoration: none;
      color: white;
      display: inline-block;
      margin: 20px;
      border-radius: 24px;
      position: relative;
    }

    .icons a:before,
    .icons a:after {
      content: '';
      position: absolute;
      left: 0;
      top: 0;
      width: 100%;
      height: 100%;
      background: inherit;
      border-radius: 100%;
      -webkit-transform: scaleX(2) scaleY(1.05);
      transform: scaleX(2) scaleY(1.05);
      clip: rect(0, 66px, 100px, 34px);
      z-index: -1;
    }

    .icons a:after {
      -webkit-transform: scaleY(2) scaleX(1.05) rotate(90deg);
      transform: scaleY(2) scaleX(1.05) rotate(90deg);
    }

<div class="icons">
    <a href="#"></a>
</div>

如果不是这种情况，你可以添加大小和边界半径到图像。在这种情况下，伪圆形边界是由背景色填充的'图标a'元素。

- 注：**这可能不是所需的效果，因为它是由背景颜色补充的。

一个二个一个一个

**SVG Solution 1:**Use a cliping-path using an svg but this is not yet supported by webkit (sticks the clipped image at the top left of the screen). See this link for more info: https://css-tricks.com/clipping-masking-css/#comment-1587234

#squircle{  
  -webkit-clip-path: url(#svg-shape);
  -moz-clip-path: url(#svg-shape);
  -o-clip-path: url(#svg-shape);
  -ms-clip-path: url(#svg-shape);
  clip-path: url(#svg-shape);
}

<img src="https://picsum.photos/400/" id="squircle">

<svg height="0" width="0" version="1.1"
     xmlns="http://www.w3.org/2000/svg">
  <defs>
  <clipPath id="svg-shape">
<path d="M100,200c43.8,0,68.2,0,84.1-15.9C200,168.2,200,143.8,200,100s0-68.2-15.9-84.1C168.2,0,143.8,0,100,0S31.8,0,15.9,15.9C0,31.8,0,56.2,0,100s0,68.2,15.9,84.1C31.8,200,56.2,200,100,200z" />
    </clipPath>
    </defs>
</svg>

- SVG解决方案2：**使用模式将图像添加为背景图像。

svg.iOS-svg {
  height: 100px;
  width: 100px;
}

<svg class="iOS-svg" viewBox="0 0 200 200">
  <defs>
    <pattern id="squircle" patternUnits="userSpaceOnUse" width="200" height="200">
        <image xlink:href="https://picsum.photos/256/" x="0" y="0" width="200" height="200" />
    </pattern>
  </defs>

    <path d="M100,200c43.8,0,68.2,0,84.1-15.9C200,168.2,200,143.8,200,100s0-68.2-15.9-84.1C168.2,0,143.8,0,100,0S31.8,0,15.9,15.9C0,31.8,0,56.2,0,100s0,68.2,15.9,84.1C31.8,200,56.2,200,100,200z" fill="url(#squircle)" />
</svg>

松鼠是不是border-radius或圆角，你必须自己画路径。

这篇文章来自figma的博客以及它们在Github中的实现。
