The provided code snippet appears to be a mix of HTML, CSS, and JavaScript. However, without more context or information about the intended functionality, it's challenging to provide a specific solution.
That being said, here are some observations and potential improvements that can be made:
1. **Consistent indentation**: The code uses both spaces and tabs for indentation. It's essential to use either one consistently throughout the codebase.
2. **Semantic HTML**: The HTML structure could be improved by using more semantic elements. For example, instead of `<div>...</div>`, consider using `<header>...</header>`, `<nav>...</nav>`, and so on.
3. **CSS selectors**: Some CSS selectors are quite specific and may not be necessary. Consider using more universal selectors to reduce the complexity of your stylesheet.
4. **JavaScript functionality**: Without knowing the intended functionality, it's difficult to suggest improvements for the JavaScript code.
If you could provide more context or information about the desired outcome, I'd be happy to help with a more specific solution.
