前端技术探索系列：CSS 工具与生态系统详解 🛠️

致读者：探索 CSS 开发工具链 👋

前端开发者们，

今天我们将深入探讨 CSS 工具与生态系统，学习如何利用现代工具提升开发效率。

构建工具 🚀

Webpack 配置

// webpack.config.js
module.exports = {
    module: {
        rules: [
            {
                test: /\.css$/,
                use: [
                    'style-loader',
                    {
                        loader: 'css-loader',
                        options: {
                            modules: true,
                            importLoaders: 1
                        }
                    },
                    'postcss-loader'
                ]
            },
            {
                test: /\.scss$/,
                use: [
                    'style-loader',
                    'css-loader',
                    'sass-loader'
                ]
            }
        ]
    },
    plugins: [
        new MiniCssExtractPlugin({
            filename: '[name].[contenthash].css'
        })
    ]
};

PostCSS 配置

// postcss.config.js
module.exports = {
    plugins: [
        require('autoprefixer'),
        require('postcss-preset-env'),
        require('cssnano'),
        require('postcss-import'),
        require('tailwindcss')
    ]
};

开发工具 🎯

CSS-in-JS 工具

// styled-components 示例
import styled from 'styled-components';

const Button = styled.button`
    background: ${props => props.primary ? '#007bff' : 'white'};
    color: ${props => props.primary ? 'white' : '#007bff'};
    padding: 0.5em 1em;
    border: 2px solid #007bff;
    border-radius: 4px;

    &:hover {
        background: ${props => props.primary ? '#0056b3' : '#e6f0ff'};
    }
`;

// CSS Modules 示例
import styles from './Button.module.css';

const Button = () => (
    <button className={styles.button}>
        Click me
    </button>
);

开发环境工具

// 开发服务器配置
module.exports = {
    devServer: {
        hot: true,
        open: true,
        port: 3000,
        overlay: true,
        stats: 'minimal'
    }
};

// CSS 热重载配置
if (module.hot) {
    module.hot.accept('./styles/main.css', () => {
        // 重新应用样式
    });
}

调试工具 🔍

浏览器开发工具

// CSS 调试助手
class CSSDebugger {
    constructor(options = {}) {
        this.options = {
            outlineColor: 'red',
            showGrid: true,
            showBoxModel: true,
            ...options
        };
        
        this.init();
    }

    init() {
        this.createDebugStyles();
        this.setupKeyboardShortcuts();
        this.initializeDevTools();
    }

    createDebugStyles() {
        const style = document.createElement('style');
        style.textContent = `
            ${this.generateDebugOutlines()}
            ${this.generateGridOverlay()}
            ${this.generateBoxModelHighlight()}
        `;
        document.head.appendChild(style);
    }

    generateDebugOutlines() {
        return `
            .debug * {
                outline: 1px solid ${this.options.outlineColor};
            }
        `;
    }

    generateGridOverlay() {
        return `
            .show-grid {
                background: linear-gradient(to right, 
                    rgba(0,0,0,0.1) 1px, 
                    transparent 1px
                ) 0 0 / 8px 8px;
            }
        `;
    }

    generateBoxModelHighlight() {
        return `
            .show-box-model * {
                box-shadow: inset 0 0 0 1px rgba(255,0,0,0.2);
            }
        `;
    }

    setupKeyboardShortcuts() {
        document.addEventListener('keydown', (e) => {
            if (e.ctrlKey && e.shiftKey) {
                switch(e.key) {
                    case 'D':
                        this.toggleDebug();
                        break;
                    case 'G':
                        this.toggleGrid();
                        break;
                    case 'B':
                        this.toggleBoxModel();
                        break;
                }
            }
        });
    }

    initializeDevTools() {
        if (window.__CSS_DEBUGGER__) {
            console.log('CSS Debugger already initialized');
            return;
        }

        window.__CSS_DEBUGGER__ = {
            toggleDebug: () => this.toggleDebug(),
            toggleGrid: () => this.toggleGrid(),
            toggleBoxModel: () => this.toggleBoxModel(),
            inspect: (selector) => this.inspect(selector)
        };
    }

    toggleDebug() {

    }

    inspect(selector) {
        const elements = document.querySelectorAll(selector);
        console.log(`Found ${elements.length} elements matching "${selector}"`);
        
        elements.forEach(element => {

                },
                computed: styles
            });
        });
    }
}

生态系统工具 💫

常用库与框架

// Tailwind CSS 配置
module.exports = {
    content: ['./src/**/*.{js,jsx,ts,tsx}'],
    theme: {
        extend: {
            colors: {
                primary: '#007bff',
                secondary: '#6c757d'
            },
            spacing: {
                '72': '18rem',
                '84': '21rem',
                '96': '24rem'
            }
        }
    },
    plugins: [
        require('@tailwindcss/forms'),
        require('@tailwindcss/typography')
    ]
};

// CSS-in-JS 主题系统
const theme = {
    colors: {
        primary: '#007bff',
        secondary: '#6c757d',
        success: '#28a745'
    },
    typography: {
        h1: {
            fontSize: '2.5rem',
            fontWeight: 'bold'
        },
        h2: {
            fontSize: '2rem',
            fontWeight: 'semibold'
        }
    },
    spacing: {
        small: '0.5rem',
        medium: '1rem',
        large: '2rem'
    }
};
