Basic Ideas:

1. After the page is loaded, insert a window to the page, and insert a close button to the window.

2. Use the setInterval () function to trigger the moves () function to start the animation.

3. moves function: first obtain the current window position, and then shift the window over time. When the window is displaced to the edge of the browser, the system reversely moves.

4. Add other events: hover the mouse over to stop the movement, move the mouse away to continue the movement, and click the button to close the window.

Ps: This special effect is not recommended to affect user experience.
