html - Tailwind CSS 不必要的空白

Question

我正在尝试使用 this admin starter template我在顺风工具箱上找到了，我正在尝试根据自己的喜好对其进行自定义。我已将模板中的代码拆分为 3 个单独的文件，如下所示，当我替换 children 时主文件中的变量，甚至类似于 test我在页面底部看到一个带有大量额外空白的滚动条，如下所示
“Main”文件导入导航栏和侧边栏，然后还有一个主页面内容的占位符

import Navbar from "@/Components/Layouts/Navbar"
import Sidebar from "@/Components/Layouts/Sidebar"

export default function Main({ name, children }) {

  return (
    <div className="bg-gray-800 flex flex-col h-screen">

      <Navbar />

      <div className="flex flex-col md:flex-row flex-grow">

        <Sidebar />

        <div className="flex-1 bg-gray-100">
          <div className="bg-gray-800 pt-3">
            <div className="rounded-tl-3xl bg-gradient-to-r from-blue-900 to-gray-800 p-4 shadow text-2xl text-white">
              <h3 className="font-bold pl-2">{name}</h3>
            </div>
          </div>
          <div className="p-4">
            {children}
          </div>
        </div>
      </div>
    </div>
  )
}

导航栏

import { useState } from "react";

export default function Navbar() {
  const [dropdownState, setDropdownState] = useState('invisible');

  const toggleDropdown = () => {
    console.log('toggle');
    if (dropdownState) {
      setDropdownState(null);
    } else {
      setDropdownState('invisible')
    }
  }

  return (
    < nav className="bg-gray-800 pt-2 md:pt-1 pb-1 px-1 mt-0 h-auto sticky w-full z-20 top-0" >

      return ' text-blue-600'
    }
  }

  const textClass = (route) => {
    if (window.location.href.indexOf(route) !== -1) {
      return ' text-white md:text-white'
    } else {
      return ' text-gray-600 md:text-gray-400'
    }
  }

  return (

编辑
这是一个带有代码的代码笔链接，可帮助调试 https://codepen.io/hcphoon01/pen/OJmXrRN
更新 我现在已经解决了一个问题，但又创建了另一个问题，我通过将最高级别的 div 更改为 <div className="bg-gray-800 flex flex-col h-screen"> 来解决空白问题。然后添加 flex-grow在包含侧边栏的 div 上，尽管现在的问题是，如果内容大于屏幕，侧边栏不会变大以适应。代码笔已更新以反射(reflect)这一点

Answer 1

检查您的 Sidebar成分。
必须是 h-auto或 h-full或 h-initial相反 h-screen .因为它放入了main组件，所以只有 main应该是 h-screen .
请更改此代码而不是使用 h-screen .

<div class="bg-gray-800 shadow-xl h-16 bottom-0 mt-12 md:relative z-10 w-full md:w-48">
