/* Modern Header and Footer Styles for JS Components */
/* This file contains the styles needed for the header.js and footer.js components */

/* ===== FOOTER 联系信息位置调整说明 =====
 * 
 * 主要控制代码位置：
 * 
 * 1. .footer-content (第291行附近)
 *    - grid-template-columns: 1fr 1fr  // 控制左右两栏分布
 *    - gap: 25px                       // 左右栏间距
 * 
 * 2. .footer-contact (第321行附近)  
 *    - justify-content: flex-start     // 水平位置：flex-start(左) | center(中) | flex-end(右)
 * 
 * 3. .contact-info-unified (第327行附近)
 *    - align-items: flex-start         // 内容对齐方式
 *    - text-align: left                // 文本对齐方式
 *    - margin-left/right: 数值         // 精确位置微调
 * 
 * 响应式调整：
 * - 平板端(768px以下): 改为单列布局，居中显示
 * - 移动端(480px以下): 联系信息居中对齐
