What is the point of.......?

What is the point of script below within the /rectangle_bottom.tpl

Code:

<SCRIPT>

if (navigator.appName.indexOf('Microsoft')>=0)

document.write("<TR><TD height='100%'><img src={$ImagesDir}/spacer.gif width=1 height=1></TD></TR>" );

else

document.write("<TR><TD><img src={$ImagesDir}/spacer.gif width=1 height=1></TD></TR>" );

</SCRIPT>

I was wondering the exact same thing, it looks like redundant code left in there. I deleted it, it does nothing other than get in the way of your layout.

actually its not redundant

This code was probably written to be cross-browser compatible. Netscape 4.0 doesn't recognize the TD tag setting where height=100%. It might just be for cosmetic looks where the cell expands all the way to the bottom to match the sides (in case your side panels extend really long), and the reason it's set to show when you have Explorer is because Explorer obeys this attribute.

The reason for the spacer.gif in both is because you want that there (or a non-breaking space if the height is needed to be greater than 1 px) so that the cell doesn't collapse. With Netscape browsers (and just for good coding practices), you should never have an empty cell.

Good thing netscape 4 is virtually extinct these day :) I've not had a netscrape 4 hit on my sites in ages. Even netscrape 6-7 only makes up 4% of hits on a site with 1.5 million visitors per year.
