如何在Next.js图像中使用Tailwind CSS

在本文中,我们将学习如何在Next.js图像中使用Tailwind CSS。Tailwind是一种流行的实用型CSS框架,简化了创建响应式Web设计的过程。它提供了一套预定义的CSS类,可用于样式化HTML元素。

Next.js 图像组件类似于< img/ >标签,但具有更好的性能、自动优化、懒加载、响应式图像渲染和有助于SEO排名的特性,需要设置宽度和高度属性。

先决条件

语法

import Image from "next/image";
<Image src="img url" alt="img name" width={100} height={100} / **>**

属性:

  • src: 图像文件的源链接
  • alt: 图像的替代名称,如果图像未呈现,则显示该名称
  • width: 图像的宽度
  • height: 图像的高度

创建一个Next.js项目并安装Tailwind CSS

步骤1:输入以下命令来创建Next.js项目

npx create-next-app@latest

步骤2: 输入项目名称,并根据您的需求选择Tailwind CSS和其他选项

What is your project named?  my-app
Would you like to use TypeScript?  No / Yes
Would you like to use ESLint?  No / Yes
Would you like to use Tailwind CSS?  Yes
Would you like to use `src/` directory?  No / Yes
Would you like to use App Router? (recommended)  No / Yes
Would you like to customize the default import alias?  No / Yes

注意: 在最新版本的Next.js中,安装Tailwind CSS和Next.js变得更简单了。

步骤3: 使用命令进入文件夹

cd my_app

方法

首先,我们将从 “next/image” 中导入一个 Image 组件,然后我们将添加以下必需的 props:src、alt、width 和 height。然后,我们将使用 Tailwind CSS 来为图片添加样式,例如添加阴影、使边框圆角、添加内边距等等。

// next.config.js
/** @type {import('next').NextConfig} */
const nextConfig = {
    reactStrictMode: true,
    images : {
        domains : ['media.geeksforgeeks.org']
    }
}
module.exports = nextConfig

示例1: 在这种方法中,使用Tailwind CSS加载并样式化了一个图像。

  • src/pages.js
import Image from "next/image"; 
  
export default function Home() { 
    return ( 
        <div className="flex flex-col p-6 m-6  
                justify-center items-center"> 
            <h1 className="text-2xl text-center  
                  font-semibold text-green-600"> 
                Geeks for Geeks Tailwind  
                Next.js Image 
            </h1> 
            <div className="p-10"> 
                <Image 
                    src= 
{"https://media.geeksforgeeks.org/wp-content/uploads/20230722121133/GFG.png"} 
                    width={300} 
                    height={300} 
                    className="shadow-2xl bg-white  
                        rounded-xl p-4 shadow-red-800"
                /> 
            </div> 
        </div> 
    ); 
}

步骤4: 要运行项目,请输入以下命令

npm run dev

然后点击链接或在浏览器中输入 localhost:3000 来打开项目

示例2: 在这种方法中,我们将使用Tailwind CSS动画来给图片添加动画效果

  • next.config.js
//next.config.js
/** @type {import('next').NextConfig} */
const nextConfig = {
reactStrictMode: true,
images : {
    domains : ['media.geeksforgeeks.org']
}
}
module.exports = nextConfig
  • src/pages.js
import Image from "next/image"; 
  
export default function Home() { 
    return ( 
        <div className="flex flex-col p-6  
                    m-6 justify-center  
                    items-center"> 
            <h1 className="text-2xl text-center  
                     font-semibold text-green-600"> 
                Geeks for Geeks Tailwind Next.js Image 
            </h1> 
            <div className="p-10 flex flex-row"> 
                <Image 
                    src= 
{"https://media.geeksforgeeks.org/wp-content/uploads/20230722121133/GFG.png"} 
                    width={300} 
                    height={300} 
                    className="shadow-2xl bg-red rounded-xl  
                     p-4 m-4  shadow-rose-400  
                     hover:rotate-45 duration-150  
                     ease-in-out "
                /> 
                <Image 
                    src= 
{"https://media.geeksforgeeks.org/wp-content/uploads/20230722121133/GFG.png"} 
                    width={300} 
                    height={300} 
                    className="shadow-2xl bg-red rounded-xl  
                     p-4 m-4 shadow-cyan-400  
                     hover:scale-125  
                     duration-150 ease-in-out "
                /> 
                <Image 
                    src= 
{"https://media.geeksforgeeks.org/wp-content/uploads/20230722121133/GFG.png"} 
                    width={300} 
                    height={300} 
                    className="shadow-2xl bg-red  
                     rounded-xl p-4 m-4  
                     shadow-green-400  
                     hover:skew-x-12  
                     duration-150 ease-in-out "
                /> 
                <Image 
                    src= 
{"https://media.geeksforgeeks.org/wp-content/uploads/20230722121133/GFG.png"} 
                    width={300} 
                    height={300} 
                    className="shadow-2xl bg-red rounded-xl  
                     p-4 m-4 shadow-pink-400  
                     hover:skew-y-12 duration-150  
                     ease-in-out "
                /> 
            </div> 
        </div> 
    ); 
}
