Create a web page with a square `div`. Apply CSS animations to create the following effects:
1. The square moves from left to right of the screen over a period of 2 seconds.
2. The square changes its background color from red to blue to green to red again, each change taking place over a period of 1 second.
3. The square rotates 360 degrees over a period of 1 second.
4. All of these animations should occur simultaneously and should be continuously repeated.
