📌Dark/Light Mode Toggle Misplaced on Small Screens

**Description:**
When the website is viewed on smaller screens, the dark/light mode toggle button is not positioned correctly.
After opening the hamburger menu, the toggle either overlaps elements or is misaligned within the navbar.

**Steps to Reproduce:**
1. Visit [My Gallery 4u](https://avinash201199.github.io/My-Gallery-4u/)
2. Reduce screen width or open it on a mobile device
3. Click the hamburger menu
4. Observe that the dark/light toggle is not properly aligned or placed

**Expected Behavior:**
The dark/light toggle should remain properly aligned and visible within the navbar, even when the menu collapses on small screens.

**Actual Behavior:**
The toggle appears misplaced or overlaps other elements when the screen size is reduced.
