4. 主题最佳实践

4.1 性能优化

<!-- 主题加载优化 -->
<link rel="preload" href="path/to/kendo.theme.css" as="style" onload="this.onload=null;this.rel='stylesheet'">
<noscript><link rel="stylesheet" href="path/to/kendo.theme.css"></noscript>

<!-- 关键CSS内联 -->
<style>
/* 关键样式内联以避免FOUC */
.k-button { 
    display: inline-block; 
    padding: 8px 16px; 
    border: 1px solid transparent;
}
</style>

<!-- CDN优化 -->
<link href="https://kendo.cdn.telerik.com/2023.3.1010/styles/kendo.default-v2.min.css" 
      rel="stylesheet" 
      crossorigin="anonymous" 
      integrity="sha384-example-hash">

4.2 可访问性支持

/* 高对比度模式支持 */
@media (prefers-contrast: high) {
    .k-button {
        border-width: 2px;
    }
    
    .k-textbox:focus {
        outline: 3px solid;
        outline-offset: 2px;
    }
}

/* 减少动画模式 */
@media (prefers-reduced-motion: reduce) {
    .k-animation-container,
    .k-widget * {
        animation-duration: 0.01ms !important;
        animation-delay: 0.01ms !important;
        transition-duration: 0.01ms !important;
    }
}

/* 键盘导航优化 */
.k-button:focus,
.k-textbox:focus,
.k-dropdown:focus {
    outline: 2px solid #005fcc;
    outline-offset: 2px;
}

4.3 主题维护建议

// 主题版本管理
const ThemeManager = {
    version: '1.0.0',
    themes: {
        light: 'kendo.default-v2.min.css',
        dark: 'kendo.dark-v2.min.css',
        custom: 'custom-theme.css'
    },
    
    // 加载主题
    loadTheme: function(themeName) {
        const themeUrl = this.themes[themeName];
        if (!themeUrl) return;
        
        // 移除旧主题
        this.removeCurrentTheme();
        
        // 加载新主题
        const link = document.createElement('link');
        link.rel = 'stylesheet';
        link.href = themeUrl;
        link.id = 'current-theme';
        document.head.appendChild(link);
        
        // 保存用户偏好
        localStorage.setItem('preferred-theme', themeName);
    },
    
    // 移除当前主题
    removeCurrentTheme: function() {
        const currentTheme = document.getElementById('current-theme');
        if (currentTheme) {
            currentTheme.remove();
        }
    },
    
    // 初始化主题
    init: function() {
        const savedTheme = localStorage.getItem('preferred-theme') || 'light';
        this.loadTheme(savedTheme);
    }
};

// 页面加载时初始化
document.addEventListener('DOMContentLoaded', function() {
    ThemeManager.init();
});
