why is some website words seem written on the top of each other?

Answer 1

Your internet font settings are probably not paralleling with the ones of the person of who created the website, and thus the line height in the CSS settings is making the text appear overlapped. You might try tampering with your font size setting in your web explorer by clicking on the 'View' menu and testing out a smaller text size.

Answer 2

that can either be caused by bad coding, or the kind of browser you're using and the settings. I use Firefox and I think it works pretty good.
