1. Click the button on this page four times to open four new windows.

2. Hover your mouse over the browser icon at the bottom of your screen (on the taskbar or dock).
   → You should see small previews of all the open windows.

3. Click on each preview to bring that window to the front and view it.

4. Try moving the windows around your screen by clicking and dragging the top bar of each one.

5. Arrange the four windows so that each takes up a quarter of your screen (top left, top right, bottom left, bottom right).

6. Once you’ve arranged them, close all four windows by clicking the small ❌ (X) in the top-right (Windows) or top-left (Mac) corner of each.

7. Click the button four more times to open four new windows again.

8. Hover your mouse over the browser icon on your taskbar/dock again.
   → This time, don’t click on the previews — just hover to see which ones are open.

9. Practice closing each window by hovering over its preview and clicking the small ❌ (X) that appears in the corner (if available), or by clicking into each window and closing them normally.

💡 Optional Challenge

• Resize this window (the one you're reading right now) by dragging the corners, so it takes up half of the screen.

• Click the button to open one more new window.

• Resize the new window so it takes up the other half of the screen.
