拓冰网站定制 
以前在github搭建过一个个人主页。链接：
现在修改下，改为一个工具页面，左侧是菜单，点击菜单在右侧显示页面。index.html改为如下：
<!DOCTYPE html> <html lang="zh-CN"> <head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <title>Xuange2026 的个人主页</title> <style> * { margin: 0; padding: 0; box-sizing: border-box; } body { font-family: -apple-system, BlinkMacSystemFont, "Segoe UI", Roboto, "Helvetica Neue", Arial, sans-serif; height: 100vh; display: flex; background: #f5f5f5; } /* 左侧菜单 */ .sidebar { width: 200px; background: #2c3e50; color: white; display: flex; flex-direction: column; overflow-y: auto; box-shadow: 2px 0 8px rgba(0,0,0,0.1); } .sidebar h2 { padding: 20px 16px 10px; font-size: 18px; font-weight: 500; border-bottom: 1px solid rgba(255,255,255,0.2); margin-bottom: 10px; text-align: center; } .menu-list { list-style: none; flex: 1; padding: 0 8px; } .menu-item { padding: 12px 16px; margin: 4px 0; border-radius: 6px; cursor: pointer; transition: background 0.2s; color: #ecf0f1; font-size: 15px; word-break: break-all; } .menu-item:hover { background: rgba(255,255,255,0.15); } .menu-item.active { background: #3498db; color: white; font-weight: 500; } /* 右侧内容区 */ .content { flex: 1; position: relative; background: white; } .iframe-container { position: absolute; top: 0; left: 0; width: 100%; height: 100%; border: none; display: none; } .iframe-container.active { display: block; } .placeholder { display: flex; align-items: center; justify-content: center; height: 100%; color: #95a5a6; font-size: 20px; } .placeholder.hidden { display: none; } /* 秘密小圆点 */ .secret-trigger{ position:fixed; bottom:6px; right:6px; width:14px; height:14px; background:#eeeeee; border-radius:50%; z-index:9998; cursor:pointer; } .secret-trigger:hover{ background:#cccccc; } /* 全屏遮罩层，用来加载独立love.html */ .love-layer{ position:fixed; inset:0; z-index:9999; display:none; } .love-layer.show{ display:block; } .love-layer iframe{ width:100%; height:100%; border:none; } .love-close{ position:fixed; top:12px; right:12px; z-index:10001; background:rgba(255,255,255,0.35); border:1px solid #d44e6c; color:#d44e6c; padding:4px 10px; border-radius:8px; cursor:pointer; font-size:13px; } .love-close:hover{ background:rgba(255,255,255,0.7); } </style> </head> <body> <div class="secret-trigger" id="secretBtn" title="秘密入口"></div> <div class="sidebar"> <h2>常用工具</h2> <ul class="menu-list" id="menuList"></ul> </div> <div class="content" id="contentArea"> <div class="placeholder" id="placeholder">👈 点击左侧菜单打开页面</div> </div> <!-- 全屏层：iframe加载独立love.html --> <div class="love-layer" id="loveLayer"> <button class="love-close" id="closeLove">← 返回工具页</button> <iframe src="love.html"></iframe> </div> <script> (function() { const menuItems = [ { name: 'JSON格式化', url: 'https://www.sojson.com/' }, { name: '百度', url: 'https://www.baidu.com/' }, { name: '必应', url: 'https://www.bing.com/' }, { name: '时间戳转换', url: 'https://tool.lu/timestamp/' }, {name: '博客', url: 'https://blog.csdn.net/u012116089?type=blog'} ]; const menuList = document.getElementById('menuList'); const contentArea = document.getElementById('contentArea'); const placeholder = document.getElementById('placeholder'); const secretBtn = document.getElementById("secretBtn"); const loveLayer = document.getElementById("loveLayer"); const closeLove = document.getElementById("closeLove"); const iframeCache = {}; let currentActiveIndex = -1; //打开全屏层（只是显示，不跳转页面，主页面状态全部保留） function openLove(){ loveLayer.classList.add("show"); } function closeLoveFunc(){ loveLayer.classList.remove("show"); } secretBtn.addEventListener("click", openLove); closeLove.addEventListener("click", closeLoveFunc); function renderMenu() { menuItems.forEach((item, index) => { const li = document.createElement('li'); li.className = 'menu-item'; li.textContent = item.name; li.dataset.index = index; li.addEventListener('click', () => switchToMenu(index)); menuList.appendChild(li); }); } function switchToMenu(index) { if (currentActiveIndex === index) return; const allItems = menuList.querySelectorAll('.menu-item'); allItems.forEach(item => item.classList.remove('active')); allItems[index].classList.add('active'); placeholder.classList.add('hidden'); if (currentActiveIndex !== -1) { const prevIframe = iframeCache[currentActiveIndex]; if (prevIframe) prevIframe.classList.remove('active'); } if (!iframeCache[index]) { createIframe(index); } iframeCache[index].classList.add('active'); currentActiveIndex = index; } function createIframe(index) { const iframe = document.createElement('iframe'); iframe.className = 'iframe-container'; iframe.src = menuItems[index].url; iframe.setAttribute('sandbox', 'allow-same-origin allow-scripts allow-popups allow-forms'); contentArea.appendChild(iframe); iframeCache[index] = iframe; } renderMenu(); })(); </script> </body> </html>还有一个love.html， 代码略。
然后上传到github的个人主页。步骤略。
网页打开效果：
ok.
