UI 左右布局优化方案

当前问题分析

布局问题: 当前为单栏垂直布局，所有内容堆叠在页面中央
空间利用率: 屏幕宽度利用率低，特别是宽屏显示器
导航效率: 表格切换和数据筛选都在顶部，操作路径长
用户体验: 缺乏现代化的应用布局，更像传统网页

优化目标

左右分栏: 左侧固定宽度导航栏，右侧主内容区
响应式设计: 适配不同屏幕尺寸
操作便捷: 减少用户操作路径，提高数据访问效率
现代化UI: 采用现代Web应用设计语言

具体优化步骤

🎯 交互易用性增强

无障碍设计原则

键盘导航: 所有交互元素支持Tab键导航
焦点指示: 清晰的焦点样式，符合WCAG 2.1标准
屏幕阅读器: 适当的ARIA标签和语义化HTML
色彩对比: 所有文本满足4.5:1的对比度要求

阶段1: 基础布局重构

1.1 HTML结构调整

<!-- 新增的布局结构 -->
<div class="app-container">
    <!-- 左侧导航栏 -->
    <aside class="sidebar">
        <!-- 导航内容 -->
    </aside>
    
    <!-- 右侧主内容区 -->
    <main class="main-content">
        <!-- 原内容移到这里 -->
    </main>
</div>

1.2 现代化CSS Grid布局

.app-container {
    display: grid;
    grid-template-columns: 260px 1fr;
    height: 100vh;
    overflow: hidden;
    font-family: -apple-system, BlinkMacSystemFont, 'Segoe UI', Roboto, sans-serif;
    background: var(--bg-secondary);
}

.sidebar {
    background: var(--bg-primary);
    border-right: 1px solid var(--border-light);
    overflow-y: auto;
    position: relative;
    box-shadow: 0 0 20px rgba(0, 0, 0, 0.05);
}

.main-content {
    overflow-y: auto;
    background: var(--bg-secondary);
    position: relative;
}

/* 响应式设计 - 更智能的断点 */
@media (max-width: 1024px) {
    .app-container {
        grid-template-columns: 240px 1fr;
    }
}

@media (max-width: 768px) {
    .app-container {
        grid-template-columns: 1fr;
    }
    
    .sidebar {
        position: fixed;
        top: 0;
        left: -260px;
        height: 100vh;
        z-index: 1000;
        transition: left 0.3s cubic-bezier(0.4, 0, 0.2, 1);
        box-shadow: 2px 0 20px rgba(0, 0, 0, 0.1);
    }
    
    .sidebar.open {
        left: 0;
    }
    
    .sidebar-backdrop {
        position: fixed;
        top: 0;
        left: 0;
        right: 0;
        bottom: 0;
        background: rgba(0, 0, 0, 0.5);
        z-index: 999;
        opacity: 0;
        visibility: hidden;
        transition: all 0.3s ease;
    }
    
    .sidebar.open + .sidebar-backdrop {
        opacity: 1;
        visibility: visible;
    }
}

阶段2: 左侧导航栏设计

        </div>
        
        <!-- 主题切换 -->
