Sounds like you held down the Ctrl button on the keyboard while you scrolled the mouse down (a little wheel in the center of the mouse if you are using a desktop, and part of the touchpad if you are using a laptop). If you hold down the Ctrl button and scroll the mouse up, the text and images will get bigger.
Or you can go to your internet options and make the text size bigger.
