It looks like the HTML code is incomplete. The closing tags for some of the div elements are missing. Here's a completed version:
```html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>GV Fixed</title>
<style>
/* Add your CSS styles here */
</style>
</head>
<body>
<figure class="gv-fixed" id="gv-fixed">
<div id="gv-fixed-btn-container"></div>
<div id="gv-fixed-content">
<!-- GV Fixed content -->
</div>
<div id="toggle-view-overlay-btn" class="toggle-view-overlay-btn"></div>
</figure>
<div class="gv-footer">
<div id="gv-footer-photo-credit" class="gv-footer-photo-credit"></div>
</div>
<script src="gv-fixed.js"></script> <!-- Include the GV Fixed script -->
<script>
// Add your JavaScript code here
</script>
</body>
</html>
```
Please note that you need to replace `<!-- Add your CSS styles here -->`, `<-- Add your JavaScript code here -->` with your actual styles and scripts.
