html - 隐藏侧边栏时添加过渡

问题描述

我使用带有两列的 css 网格创建了我的布局：

.app {
    height: 100vh;
    display: grid;
    grid-template-columns: 260px 1fr;
    grid-template-rows: 56px 1fr 40px;
    grid-template-areas: "menu header" "menu content" "menu footer";
}

现在我想添加一个平滑的过渡。我做了以下事情：当我点击标题组件的切换按钮时，我隐藏了我的侧边栏组件。

.hide-menu {
    grid-template-areas:
        "header header"
        "content content"
        "footer footer";
}

问题是布局正在破坏。

我不知道在布局组件的 translateX 中作为参数传递什么。我想这是我的问题。

.openMain {
    transform: translateX(-260px); <<<<<<<<
    transition: all 500ms linear;
}

你能帮我找出我哪里出错了吗？

    computed: mapState(["isMenuVisible"]),
    components: {
        Lheader,
        Lfooter,
        Lmenu,
    },
};

解决方案

只需调整侧边栏的宽度，并将网格中的列宽设置为自动。

Grid将为您进行调整。

在片段中，只需将网格悬停即可隐藏侧边栏

.app {
  height: 100vh;
  display: grid;
  grid-template-columns: auto 1fr;
  grid-template-rows: 56px 1fr 40px;
  grid-template-areas: "menu header" "menu content" "menu footer";
}

.menu {
   grid-area: "menu";
   width: 260px;
   height: 100vh;
   background-color: lightblue;
   transition: width 1s;
   overflow: hidden;
}

.app:hover .menu {
    width: 0px;
}

.header {
   grid-area: header;
}

.content {
   grid-area: content;
}

.footer {
   grid-area: footer;
}
<div class="app">
  <div class="menu">MENU</div>
  <div class="header">HEADER</div>
  <div class="content">CONTENT</div>
  <div class="footer">FOOTER</div>
</div>
