在菜单上隐藏动画不适用于其所有子项

Question

正如您在下面的代码片段中看到的，当我单击菜单图标时，显示/隐藏动画正确完成，但这不适用于项目的内容。

此外，当 class 'active-menu' 附加到菜单时，'item' class 正确应用显示：网格属性，但作为一旦它关闭，项目的内容就不再被视为菜单的直接子项，而是容器的直接子项，这是错误的。

我不清楚问题出在哪里，所以我需要你的建议（希望我解释清楚了）

let topBar = document.getElementById("tobBar");
let menu = document.getElementById("menu");

ico.addEventListener('click', (e) => {
    ico.classList.toggle("toggle-color");
    menu.classList.toggle("active-menu");
})

body {
    background-color: #eee;
}
.container {
    width: 370px;
    height: 550px;
    background: darkgray;
    z-index: -2;
    margin: 0 auto;
    border-radius: 20px;
}

/*  *   * TOP BAR  *   *   */

.top-bar {
    height: 50px;
    width: 100%;
    background:  #00b0ff;
    display: flex;
    align-items: center;
    z-index: 999;
    border-top-left-radius: inherit;
    border-top-right-radius: inherit;
}

.top-bar-ico {
    width: 50px;
    text-align: center;
    cursor: pointer;
    z-index: 999;
}

.toggle-color {
    color: white;
}

/*  *   *   *   *   */

/*  *   *  MENU *   *   */

.menu {
    height: 500px;
    transition: 0.5s linear;
    width: 0;
    z-index: 999;
    display: flex;
    flex-direction: column;
    padding: 0 5px;
}

.active-menu {
    width: 90%;
    background:  #00b0ff;
    z-index: 999;
    border-bottom-left-radius: inherit;
}

.active-menu > * {
    background-color: white;
}

.menu > .item {

}

    margin-top: 10px;
}

    display: grid;

Answer 1

您需要将 overflow:hidden 设置为 .menu。见下文：

let topBar = document.getElementById("tobBar");
let menu = document.getElementById("menu");

ico.addEventListener('click', (e) => {
  ico.classList.toggle("toggle-color");
  menu.classList.toggle("active-menu");
})

body {
  background-color: #eee;
}

.container {
  width: 370px;
  height: 550px;
  background: darkgray;
  z-index: -2;
  margin: 0 auto;
  border-radius: 20px;
}


/*  *   * TOP BAR  *   *   */

.top-bar {
  height: 50px;
  width: 100%;
  background: #00b0ff;
  display: flex;
  align-items: center;
  z-index: 999;
  border-top-left-radius: inherit;
  border-top-right-radius: inherit;
}

.top-bar-ico {
  width: 50px;
  text-align: center;
  cursor: pointer;
  z-index: 999;
}

.toggle-color {
  color: white;
}


/*  *   *   *   *   */


/*  *   *  MENU *   *   */

.menu {
  height: 500px;
  transition: 0.5s linear;
  width: 0;
  z-index: 999;
  display: flex;
  flex-direction: column;
  overflow-x:hidden;
}

.active-menu {
  width: 90%;
  padding: 0 5px;
  background: #00b0ff;
  z-index: 999;
  border-bottom-left-radius: inherit;
}

.active-menu>* {
  background-color: white;
}


/*  *   *   *   *   */


/*  *   * MENU ITEMS  *   *   */

.menu>.item {
  height: 50px;
}

.item:not(:first-child) {
  margin-top: 10px;
}

.item {
  display: grid;
  grid-template-columns: 50px 1fr;
  grid-gap: 5px;
}
