The site looks great.
Thing is not all PC's will have the Vivaldi font. If the user doesn't have a
font the browser will substitute. Any font in use online should belong to
the group of 'core fonts', fonts that every one should have. The core fonts
are displayed on the page -
http://www.microsoft.com/typography/fonts/default.aspx
When any other font is desired it should be converted to an image. Your logo
for example should be an image. I'd suggest two images, one with the bath
and body tag and one without.
You can create the image on your favorite image editor tool or you can
optionally try and use Pub to create the image - see

the later versions).

When I put my site up on my computer it looks exactly how it should, but
when I log on with other computers it is inaccurate. Would you please log on
and let me know what you think? Thanks, Deb
