我正试图制作一个菜单,其中的子菜单周围有一个连续的边框。下面的代码显示了如何为每个单独的菜单和子菜单制作边框,但它们之间有边框。

<nav id="menu" class="hidden 950px:flex space-x-6 text-sm">
    <a href="\welcome" class="p-1 hover:text-cream">HOME</a>

    <!-- Shop Dropdown -->
    <div class="relative group">
    <button class="flex items-center p-1 hover:text-cream group-hover:text-cream group-hover:border">

正如你所看到的,顶部菜单边框和子菜单边框不需要在那里,但我想要一些看起来像图片的东西。

从中删除底部边框 <button> 元素:

<button class="â¦ group-hover:border-b-0">

为添加不透明的背景颜色 <按钮> 元素。这将隐藏子菜单顶部边框的部分:

<button class="â¦ bg-[steelblue]">

确保 <按钮> 元素堆叠在子菜单的顶部:

<button class="â¦ relative z-20">

将子菜单元素向上移动一个像素,使顶部边框被上述内容隐藏 <按钮> 元素:

<ul class="â¦ -translate-y-px">

删除左上角圆角,使左边缘看起来更无缝:

<ul class="â¦ rounded-tl-none">

tailwind.config = {

        cream: 'Moccasin',

    screens: {
