难以将蓝色变为透明

Question

如何将蓝色变为透明？ https://jsfiddle.net/o64znkc5/

这就是我想要在代码中做的所有事情。

我怎么能做到这一点？

它要求我提供更多信息，但仅此而已。

我不知道该怎么做。

.exit {
  top: auto;
  bottom: -47.63px;
  margin: auto;
  right: 0;
  left: 0;
  width: 47.63px;
  height: 47.63px;
  cursor: pointer;
  border: none;
  background: none;
  padding: 0;
  border-radius: 50%;
  clip-path: circle(50%);

}

.exit svg {
  fill: red;
}

      <button class="exit" type="button" aria-label="Close">

Answer 1

<path fill="blue"> 到 <path fill="transparent"> 在第 7 行

<path fill="transparent" d="m-101.116-101.116m169.705 11.313a113 113 0 00-137.178 0l68.589 68.59zm-158.392 21.214a113 113 0 000 137.178l68.59-68.589zm21.214 158.392a113 113 0 00137.178 0l-68.589-68.59zm158.392-21.214a113 113 0 000-137.178l-68.59 68.589z" />

Answer 2

您可以在标签中设置不透明度，但正如您将在示例中看到的那样，蓝色形状位于红色圆圈上方，因此我认为调整透明度不会产生您正在寻找的效果。

<path fill="blue" opacity="50%" d="m-101.116-101.116m169.705 11.313a113 113 0 00-137.178 0l68.589 68.59zm-158.392 21.214a113 113 0 000 137.178l68.59-68.589zm21.214 158.392a113 113 0 00137.178 0l-68.589-68.59zm158.392-21.214a113 113 0 000-137.178l-68.59 68.589z" />

我建议您更改创建 svg 的方式，从红色形状中打出蓝色形状，然后导出 svg，这将为您提供您正在寻找的结果，除非您只想显示红色圆圈?

编辑：您的图形由从左到右相互叠加的以下形状组成。最右边的图像是由其他三个组成的最终图形。所以使蓝色透明会显示一个红色圆圈。

Answer 3

您现在拥有它的方式是不可能归档它transparent 或none 尽管您可以将其填充为白色作为背景。

.exit {
  top: auto;
  bottom: -47.63px;
  margin: auto;
  right: 0;
  left: 0;
  width: 47.63px;
  height: 47.63px;
  cursor: pointer;
  border: none;
  background: none;
  padding: 0;
  border-radius: 50%;
  clip-path: circle(50%);

}

svg,use{fill:blue}



button:hover svg, 
button:hover use
{fill:white}

<button class="exit" type="button" aria-label="Close">
        <svg width="100%" height="100%" viewBox="-144 -144 288 288">
          <g id="exit">
            <title>exit</title>
            <path fill="red" d="m-101.116-101.116a143 143 0 11202.232 202.232a143 143 0 01-202.232-202.232zzzz" />
            <circle cx="0" cy="0" r="113" fill="red" />
            <path d="m-101.116-101.116m169.705 11.313a113 113 0 00-137.178 0l68.589 68.59zm-158.392 21.214a113 113 0 000 137.178l68.59-68.589zm21.214 158.392a113 113 0 00137.178 0l-68.589-68.59zm158.392-21.214a113 113 0 000-137.178l-68.59 68.589z" />
          </g>
        </svg>
      </button>

      <button class="exit" type="button" aria-label="Close">
        <svg width="100%" height="100%" viewBox="-144 -144 288 288">
          <use href="#exit" />
        </svg>
      </button>

      <button class="exit" type="button" aria-label="Close">
        <svg width="100%" height="100%" viewBox="-144 -144 288 288">
          <use href="#exit" />
        </svg>
      </button>
      <button class="exit" type="button" aria-label="Close">
        <svg width="100%" height="100%" viewBox="-144 -144 288 288">
          <use href="#exit" />
        </svg>
      </button>

但是，如果您需要它是透明的，我会像这样更改代码：我正在使用由两条路径制成的蒙版来刺穿红色底座。请注意，在面具中，应该是一个洞的地方被填充为白色，而可见部分保持为黑色。

.exit {
  top: auto;
  bottom: -47.63px;
  margin: auto;
  right: 0;
  left: 0;
  width: 47.63px;
  height: 47.63px;
  cursor: pointer;
  border: none;
  background: none;
  padding: 0;
  border-radius: 50%;
  clip-path: circle(50%);

}

svg,use{fill:blue}

button:hover svg,
button:hover use
{fill:none}

  <button class="exit" type="button" aria-label="Close">
        <svg width="100%" height="100%" viewBox="-144 -144 288 288">
          <g id="exit">

            <path fill="red" mask="url(#m)"  d="m-101.116-101.116a143 143 0 11202.232 202.232a143 143 0 01-202.232-202.232zzzz" />

            <path fill="black" d="m-101.116-101.116m169.705 11.313a113 113 0 00-137.178 0l68.589 68.59zm-158.392 21.214a113 113 0 000 137.178l68.59-68.589zm21.214 158.392a113 113 0 00137.178 0l-68.589-68.59zm158.392-21.214a113 113 0 000-137.178l-68.59 68.589z" />

          </g>
        </svg>
      </button>

      <button class="exit" type="button" aria-label="Close">
        <svg width="100%" height="100%" viewBox="-144 -144 288 288">
          <use href="#exit" />
        </svg>
      </button>

      <button class="exit" type="button" aria-label="Close">
        <svg width="100%" height="100%" viewBox="-144 -144 288 288">

          <use href="#exit" />
        </svg>
      </button>

还有一个观察：为了保持一致性，我将只在按钮内使用 <use> 元素，方法是使 svg 元素不可见，宽度 =“0”高度 =“0”和位置：绝对；

您也不需要按钮内的 svg 元素内的 width="100%" 。默认情况下，它们的宽度为 100%

.exit {
  top: auto;
  bottom: -47.63px;
  margin: auto;
  right: 0;
  left: 0;
  width: 47.63px;
  height: 47.63px;
  cursor: pointer;
  border: none;
  background: none;
  padding: 0;
  border-radius: 50%;
  clip-path: circle(50%);
}

svg[width = "0"]{
position:absolute;
left:-100em;}

use{fill:blue}
button:hover use
{fill:none}

<svg width="0" height="0">
          <g id="exit">
            <title>exit</title>
            <circle cx="0" cy="0" r="113"  />
            <path fill="red" mask="url(#m)"  d="m-101.116-101.116a143 143 0 11202.232 202.232a143 143 0 01-202.232-202.232zzzz" />
