In Netscape 4 the table borders are showing. NN4 has limited support for
inline styles - they may be followed, ignored, or may crash the browser.
Change the inline styles (style="blah") to an embedded or external style
sheet, or replace them with "conventional" HTML
example:
<table border="0"> instead of <table style="border-width:0">
Firefox 1.0 is also having problems, possibly because the style used
conflicts with itself - border-style:none; border-width:medium; (the border
that is not there has a medium width)
Your Word Art on the splash page does not show in any browser other than
IE5.5 and later. The down-level images have not been uploaded to the
server.
You should also remove all spaces from file and folder names.
PS Why the image of Westminster and the wheel? Wouldn't Greenwich
Observatory or the Maritime Museum be more appropriate?
