Certainly! To do this, I'll provide you with SVG code that you can add to your `index.html` file to create the image of a sunset through the mountains. Here's how it might look:
```html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Sunset Through Mountains</title>
</head>
<body>
<svg width="800" height="600" xmlns="http://www.w3.org/2000/svg">
<!-- Background sky -->
<rect width="100%" height="100%" fill="#87CEEB"/>
<!-- Sun -->
<circle cx="650" cy="150" r="50" fill="#FFD700"/>
<!-- Mountains -->
<path d="M0,600 L200,300 L350,500 L500,250 L750,400 L800,600 Z" fill="#8B4513"/>
<path d="M0,600 L150,450 L300,550 L450,400 L800,600 Z" fill="#A0522D"/>
<!-- Sunset glow -->
<ellipse cx="650" cy="150" rx="250" ry="100" fill="#FF7F50" opacity="0.5"/>
</svg>
</body>
</html>
```
This code will create a simple SVG image of a sunset with the sun partially visible behind some mountains on a blue sky background. The colors and shapes are quite basic, so you can modify them to get more detailed or realistic results if needed.
You can paste this code into your `index.html` file to display the image in your web browser. Let me know if you need any adjustments!
