如何在路徑內的圓圈上應用指標事件？

如何在代碼中修復它以便洗掉空格？

https://jsfiddle.net/k14svx2q/

我怎樣才能從代碼中洗掉空格？

有沒有辦法修復或調整它以便沒有空白？

指標事件應該只應用于路徑內的“圓圈”。

.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%;
  animation: fadeInExit 2s forwards 0s;
  opacity: 0;
  pointer-events: none;
}

@keyframes fadeInExit {
  99% {
    pointer-events: none;
  }

  100% {
    pointer-events: initial;
    opacity: 1;
  }
}

.exit:hover .exitHover {
  fill: green;
}

      <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 class="exitHover" d="m-143 0a143 143 0 1 1 286 0 143 143 0 0 1 -286 0m128-112a113 113 0 0 0 -97 97h97zm-97 127a113 113 0 0 0 97 97v-97zm127 97a113 113 0 0 0 97 -97h-97zm97-127a113 113 0 0 0 -97 -97v97z" transform="rotate(45)" fill="red" />
          </g>
        </svg>
      </button>

我被建議這樣做：

<circle cx="0" cy="0" r="144" fill="transparent" />

但這不起作用：https : //jsfiddle.net/vnghab8k/

.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%;
  animation: fadeInExit 2s forwards 0s;
  opacity: 0;
  pointer-events: none;
}

@keyframes fadeInExit {
  99% {
    pointer-events: none;
  }

  100% {
    pointer-events: initial;
    opacity: 1;
  }
}

.exit:hover .exitHover {
  fill: green;
  cursor: pointer;
}

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

            <circle cx="0" cy="0" r="144" fill="transparent" />
            <path class="exitHover" d="m-143 0a143 143 0 1 1 286 0 143 143 0 0 1 -286 0m128-112a113 113 0 0 0 -97 97h97zm-97 127a113 113 0 0 0 97 97v-97zm127 97a113 113 0 0 0 97 -97h-97zm97-127a113 113 0 0 0 -97 -97v97z" transform="rotate(45)" fill="red" />
          </g>
        </svg>
      </button>

uj5u.com熱心網友回復：

使圓外區域不可懸停的一種方法是使用 clip-path 將父物件剪輯成一個圓圈：

.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%;
  animation: fadeInExit 2s forwards 0s;
  opacity: 0;
  pointer-events: none;
   clip-path: circle(50%);
}

@keyframes fadeInExit {
  99% {
    pointer-events: none;
  }

  100% {
    pointer-events: initial;
    opacity: 1;
  }
}

.exit:hover .exitHover {
  fill: green;
}

      <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 class="exitHover" d="m-143 0a143 143 0 1 1 286 0 143 143 0 0 1 -286 0m128-112a113 113 0 0 0 -97 97h97zm-97 127a113 113 0 0 0 97 97v-97zm127 97a113 113 0 0 0 97 -97h-97zm97-127a113 113 0 0 0 -97 -97v97z" transform="rotate(45)" fill="red" />
          </g>
        </svg>
      </button>
