鏈接（所有div上方的href）

Question

嗨，這是我在網站右側有一個滑動菜單且位置固定的情況。 並且有一個鏈接“”，我想在其上方浮動絕對位置或相對位置，例如z，但我添加z-index10000。絕對位置或固定位置不顯示。 在滑塊div之外。

請檢查圖像。 檢查綠色圓圈

注意： 打開菜單后，會提示#menu關閉

的CSS和HTML說實話我有一個困難時期，謝謝

<a href="#menu" class="close" style="-webkit-tap-highlight-color: rgba(0, 0, 0, 0);"></a>



#menu .close {
            background-image: url("images/close.svg");
            background-position: 4.85em 1em;
            background-repeat: no-repeat;
            border: 0;
            cursor: pointer;
            display: block;
            height: 3em;
            position: fixed;
            right: 541px;
            top: 0;
            z-index: 50000;
            display: block;
            vertical-align: middle;
            width: 7em;
        }

任何時候要將元素絕對放在元素之上，都想將父元素設置為position:relative並將子元素放在父元素中。

<div class="parent">
   <a class="child">Child</a>
</div>

.parent {
  position: relative;
  z-index: 1;
}

.child {
  position: absolute;
  z-index: 2;
  top: 0; //style to taste
  left: 0; //style to taste
}
