Just yesterday i pressed Ctrl+C (well i think it was this) and now my whole internet server has become doubled sized and everything is massive. I don’t know how I did it, but i can’t seem to get it to go away!!! Can anyone please tell me what I have done and how to remedy it? Thankyou very much in advance !!! 
I’m guessing it’s your browser that’s enlarged, and the text that’s massive? It would help if you told us what browser you’re using, and what computer platform, but, generally, you can control the appearance of your browser through the ‘view’ menu at top and resize it by dragging the edges.
Go to View, text size, and set it to medium.
You might have accidentally moved the mouse wheel while doing this. Ctrl + Mousewheel is used by Internet Explorer to change the text size that is displayed.
