css - 如何将 Google One 样式的多色边框添加到圆形图像？

问题描述

我正在为我所在大学的 Google DSC 俱乐部创建一个网站，我想在网站上的圆形投资组合图像中添加一个Google One 风格的边框。

我想知道如何使用 CSS 来实现这一点，但预渲染的 Photoshop 或 Illustrator 技巧也可以。

我试图修改这个答案中给出的一些代码，但我无法达到完美的效果。

.test {
  margin: 25px 0;
  width: 200px;
  height: 200px;
  border-radius: 50%;
  border: 12px solid transparent;
  background-size: 100% 100%, 50% 50%, 50% 50%, 50% 50%, 50% 50%;
  background-repeat: no-repeat;
  background-image: linear-gradient(white, white), 
                    linear-gradient(30deg, #ea4335 36%, #4285f4 30%),
                    linear-gradient(120deg, #4285f4 36%, #34a853 30%),
                    linear-gradient(300deg, #fbbc04 36%, #ea4335 30%),
                    linear-gradient(210deg, #34a853 36%, #fbbc04 30%);
  background-position: center center, left top, right top, left bottom, right bottom;
  background-origin: content-box, border-box, border-box, border-box, border-box;
  background-clip: content-box, border-box, border-box, border-box, border-box;
  transform: rotate(90deg);
}
<div class="test"></div>

如您所见，边框颜色未正确对齐。

有什么方法可以使用更简单的方法来实现这一点吗？

谢谢！

解决方案

SVG 选项

要创建圆形的多色扇区，请使用stroke-dasharray

计算行和空格的长度：

对于半径R = 100px 周长 =2 * 3.1415 * 100 = 628.3 px

为了使直线等于圆的四分之一，我们计算属性stroke-dasharray

628.3 / 4 = 157.075空间将是圆长度的 3/4 =471px

但由于蓝色、红色和绿色扇区的长度略大于四分之一圆，我们添加了这个差异。中风破折号=“183.255 445.045”

stroke-dashoffset = "78.54"将扇区的起点移动圆周的 1/8

一个部门的例子 

<svg version="1.1" xmlns="http://www.w3.org/2000/svg" 
    xmlns:xlink="http://www.w3.org/1999/xlink"
	     width="250" height="250" viewBox="0 0 250 250" > 
		 
<circle cx="125" cy="125" r="100" fill="none" stroke="#d3d3d3" stroke-width="8" />		 
 		 
<circle id="blue" cx="125" cy="125" r="100" fill="none" stroke="#4285F4" stroke-width="8" stroke-dasharray="183.255 445.045" stroke-dashoffset="78.54" /> 
 
 </svg>

我们还为其他颜色部门设置了属性。

<svg version="1.1" xmlns="http://www.w3.org/2000/svg" 
    xmlns:xlink="http://www.w3.org/1999/xlink"
	     width="250" height="250" viewBox="0 0 250 250" >  

		 
<circle id="blue" cx="125" cy="125" r="100" fill="none" stroke="#4285F4" stroke-width="8" stroke-dasharray="183.255 445.045" stroke-dashoffset="78.54" /> 

  <circle id="red" cx="125" cy="125" r="100" fill="none" stroke="#EA4335" stroke-width="8" stroke-dasharray="203.255 425.045" stroke-dashoffset="281.9" /> 

  <circle id="gold" cx="125" cy="125" r="100" fill="none" stroke="#FABB04" stroke-width="8" stroke-dasharray="78.54 549.76" stroke-dashoffset="340	" /> 
 
   <circle id="green" cx="125" cy="125" r="100" fill="none" stroke="#34A852" stroke-width="8" stroke-dasharray="183.255 445.045" stroke-dashoffset="525.225	" /> 
 
 </svg>

添加图像并使用蒙版将其剪切以适合圆圈

<svg version="1.1" xmlns="http://www.w3.org/2000/svg" 
    xmlns:xlink="http://www.w3.org/1999/xlink"
	     width="40%" height="40%" viewBox="0 0 250 250" >  

 <defs> 
  <mask id="msk1"> 
    <rect width="100%" height="100%" fill="black" />
   <circle cx="125" cy="125" r="100" fill="white" stroke-width="20" stroke="black"  />
  </mask>
</defs>

 <image xlink:href="https://i.stack.imgur.com/UsGg5.jpg" x="0" y="23" width="100%" height="100%" mask="url(#msk1)" />	
		 
<circle id="blue" cx="125" cy="125" r="100" fill="none" stroke="#4285F4" stroke-width="8" stroke-dasharray="183.2 445.1" stroke-dashoffset="78.54" /> 

  <circle id="red" cx="125" cy="125" r="100" fill="none" stroke="#EA4335" stroke-width="8" stroke-dasharray="203.3 425.1" stroke-dashoffset="281.9" /> 

  <circle id="gold" cx="125" cy="125" r="100" fill="none" stroke="#FABB04" stroke-width="8" stroke-dasharray="80 549.7" stroke-dashoffset="345	" /> 
 
   <circle id="green" cx="125" cy="125" r="100" fill="none" stroke="#34A852" stroke-width="8" stroke-dasharray="183.2 445.1" stroke-dashoffset="525.2	" /> 
 
 </svg>

该解决方案是自适应的，并且在所有现代浏览器中都可以正常工作，包括IE11，Edge

OP没有问，但也许这个补充对他或其他人有用。

SVG+CSS动画

为了给您的应用程序增添趣味，我添加了动画选项。

#1。笔画围绕图像旋转的动画

  • 用组标签包裹所有形成多色线的圆圈 <g>

  • fill ="none"fill ="transparent"当您将鼠标悬停在整个圆圈上时，替换为动画工作
