d_kc,
I’m not sure that the issue is with the fonts. That is probably the case that the font settings are different on each installation of your browsers. You could easily rule that out by changing the font size under appearance in the Safari settings.
There are people on here who are infinitely more qualified than I am but I would start by looking at your body width.
‘body {
background: #DDDDDD;
width: 985px;
color: #000000;
font-size: 12px;
font-family: Arial, Tahoma, Verdana;
margin: 0px auto 0px;
padding: 0px;
}
#wrap {
background: #FFFFFF;
width: 945px;
margin: 10px auto 10px;
padding: 0px 5px 20px 5px;
border: 10px solid #f6f6f6;
}’
For example your wrap is smaller than your body. Try increasing the size of your wrap. Alternatively, you could try decreasing the size of your 3rd column a bit.
Good luck!
