javascript - 如何使用 Next.js 将 PNG 徽标添加到 Tailwind CSS 导航栏？

问题描述

这是代码，我想添加一个 PNG 徽标来代替 SVG 徽标，但是每次我添加一个img元素时，都没有渲染任何内容。我要添加的图像/徽标必须与 SVG 徽标大小相同。

在此处输入图像描述

import Link from 'next/link';
    import { useState } from 'react';
    
    export const Navbar = () => {
      const [active, setActive] = useState(false);
    
      const handleClick = () => {
        setActive(!active);
      };
    
      return (
        <>

解决方案

使用 next/image，这些是一些示例。

Layout = fill

preview - https://image-component.nextjs.gallery/layout-fill

Layout = fixed

Layout = responsive
