`, `<link rel="stylesheet" href="/assets/css/style.css">
</head>`, `<body>` closing tags need to be added to the document.

The DOM markup necessitates a topbar with the specified logo text and navigation anchors linking to the thirteen content sections. The header will include the navigation links, and the main content will organize the thirteen sections.


The website structure requires defining thirteen distinct sections with unique IDs. Each section will be populated with specific content elements like headers, images, and data points.  The button "申请体验" will link to the contact section (`#contact`).

I am focusing on implementing the thirteen website sections as specified, integrating their respective content and features. The navigation menu will link to these thirteen sections, allowing users to navigate between content components.
