+如何给其他网站添加在线玩家嵌入式卡片
+
+以下是css，放到head里面，也可以搞个单独的css文件放：
+<style>
+        .draggable-card {
+            position: fixed;
+            top: 20px;
+            left: 20px;
+            width: 300px;
+            height: 350px;
+            border-radius: 12px;
+            box-shadow: 0 6px 18px rgba(0, 0, 0, 0.2);
+            overflow: hidden;
+            resize: both;
+            z-index: 1000;
+            background: white;
+        }
+
+        .drag-handle {
+            background: linear-gradient(135deg, #1e88e5, #0d47a1);
+            color: white;
+            padding: 10px 16px;
+            cursor: move;
+            font-weight: bold;
+            user-select: none;
+            display: flex;
+            justify-content: space-between;
+            align-items: center;
+        }
+
+        .close-btn {
+            background: rgba(255, 255, 255, 0.2);
+            border: none;
+            color: white;
+            border-radius: 50%;
+            width: 24px;
+            height: 24px;
+            cursor: pointer;
+            display: flex;
+            align-items: center;
+            justify-content: center;
+            font-weight: bold;
+            transition: background 0.2s;
+        }
+
+        .close-btn:hover {
+            background: rgba(255, 255, 255, 0.3);
+        }
+
+        .draggable-card iframe {
+            width: 100%;
+            height: calc(100% - 40px);
+            border: none;
+        }
+</style>
+
+
+
+
+
+以下是卡片本体，直接塞进html里面：
+<div class="draggable-card" id="serverCard">
+        <div class="drag-handle">
+            <span>服务器状态 (可拖动)</span>
+            <button class="close-btn" id="closeBtn">×</button>
+        </div>
+        <iframe src="http://localhost:60048/embed" frameborder="0"></iframe>
+</div>
+
+
+
+
+
+以下是js脚本，可以跟着放script里面，也可以单独放个js文件：
+<script>
+        const card = document.getElementById('serverCard');
+        const handle = card.querySelector('.drag-handle');
+        const closeBtn = document.getElementById('closeBtn');
+
+        let isDragging = false;
+        let offsetX, offsetY;
+
+        handle.addEventListener('mousedown', (e) => {
+            if (e.target === closeBtn) return;
+
+            isDragging = true;
+            offsetX = e.clientX - card.getBoundingClientRect().left;
+            offsetY = e.clientY - card.getBoundingClientRect().top;
+            card.style.cursor = 'grabbing';
+        });
+
+        document.addEventListener('mousemove', (e) => {
+            if (!isDragging) return;
+            card.style.left = (e.clientX - offsetX) + 'px';
+            card.style.top = (e.clientY - offsetY) + 'px';
+        });
+
+        document.addEventListener('mouseup', () => {
+            isDragging = false;
+            card.style.cursor = '';
+        });
+
+        closeBtn.addEventListener('click', () => {
+            card.style.display = 'none';
+
+            // setTimeout(() => { card.style.display = 'block'; }, 2000);  // 关闭后超时重新显示，这里暂时放着，看需求
+        });
+</script>
