* **Repetitive jQuery Handlers:** Refactor the seven identical event listeners using a shared class selector to dramatically enhance maintainability, salting the code with DRY principles. * **Imperative Styling:** Avoid applying CSS rules directly via `.css()`; transition to managing presentation entirely by toggling predefined CSS classes. * **Responsiveness Implementation:** Replace the static `window.screen.width` check with dynamic CSS media queries or `window.matchMedia` for robust layout adjustments. * **Code Structure Flaw:** Define utility functions like `removeall()` outside conditional blocks for wider scope and improved structure clarity.
