有没有办法使用 CSS 形状复制下面的图像设计？我无法重现图像和蓝色背景之间的曲线。

我尝试使用边框但不起作用：

我有 Mozilla Firefox 和 Google Chrome，但我在使用 Microsoft Edge 和 Internet Explorer 时遇到问题。

【问题讨论】：

我猜你需要这个，这样你就可以轻松地在正确的区域内动态交换图像（从管理面板/CMS/等）。如果您没有更改蓝色的动态 CSS 主题，请进一步阅读。否则，请停在这里:)。如果是这种情况，甚至更多，如果您想在所有浏览器上工作，我会将左侧图像切片为 png，并将其用作右侧图像的蒙版。右边的那个会在左边的下面。

标签： css css-shapes

【解决方案1】：

在我看来，实现这一目标的最佳方法是正确使用 overflow: hidden、border-radius、width 和 height 属性

<div class='container' style='position: relative; overflow: hidden; width: 200px; height: 300px; background-color: #161f6e;'>
  <div class='divider' style='position: absolute; left: 26px; top: -100px; width: 300px; height: 500px; border-radius: 100% 0 0 60%; background-color: #52b9c0;'></div>
  <div class='image' style='position: absolute; left: 60px; top: -100px; width: 300px; height: 500px; border-radius: 50% 0 0 50%; background-color: #000000;'></div>
</div>

在所有给定浏览器（Chrome、Firefox、IE 11、Edge）中测试

【解决方案2】：

我只使用了border-radius 和一些transform: rotate 属性来解决您的问题，完全没有使用clip-path 来保证将支持更多的浏览器，包括MS IE 和Edge。

我还创建了一个 Codepen here。

这适用于我的 MS Edge 浏览器。

希望对你有帮助？

【讨论】：

@jameshwartlopez 我刚刚更新了我的答案，如果你之前看过的话。我还添加了对旧版 IE 和 Safari 的支持。

【解决方案3】：

我假设您已经为其他浏览器排序了 CSS，并且正在寻找 IE/Edge 选项。

我想到了两个选项，但都不是理想的，所以这真的取决于你想走多远

在您的相关课程中设置 border-radius 有效：

  border-top-left-radius: 100%;
  border-bottom-left-radius: 50%;

这接近完美的圆形切口，但不如clip-path 灵活

According to MDN，指定 clip-path 对 HTML 元素没有影响，但在 SVG 元素上受支持。然后，如果您无论如何都要生成页面，则可以在 inline-SVG 内生成边框

<div class="home-header-image">
    <svg>     
        <defs><!-- define your clipping path here -->
          <clipPath id="clipping-path">
            <circle cx="760" cy="400" r="650" style="stroke: #0000; fill: #000000;" />
          </clipPath>         
        </defs>
        <!-- order of elements matters here - latter gets drawn over former, so the image goes to the bottom -->
        <circle id="curve-border" cx="740" cy="400" r="700" style="stroke:#006600; fill:#00cc00"/><!-- colored border -->
        <image id="image" clip-path="url(#clipping-path)" width="750" height="500" xlink:href="https://images.unsplash.com/photo-1558981001-5864b3250a69?ixlib=rb-1.2.1&ixid=eyJhcHBfaWQiOjEyMDd9&auto=format&fit=crop&w=750&q=80" />
    </svg>
</div>

这显然会改变您当前的页面布局方式，但它可能会为您提供所需的一致性。另一个优势 - 您可以在您选择的编辑器中起草 SVG，然后将其用作以编程方式生成最终外观的起点。希望探索这条途径会产生一些结果。

【解决方案5】：

您可以使用img2css，这是一个允许您将图像转换为纯 CSS 的工具。截取该部分的屏幕截图或使用图像编辑器（如 Photoshop）并以您喜欢的方式更改图像，将完成的图像上传到网站上，然后您将获得纯 CSS。

您可以考虑沿外部形状使用径向背景：
