Netscape and the thin black line

[Vicki Falkland]

Hi folks,

Once upon a time, it was possible to create a thin black line across part
of a table with the following code:

<td> 
<img src="blank.gif" height="1" width="1" alt="" >
</td>

I've been looking at one of our older, defunct sites on newer versions of
Netscape, just out of curiosity.

Funny thing is, Navigator stand-alone 4.08 displays it just fine, but newer
Netscapes (6+) don't collapse the table row to a thin line - it displays it
at full height as if there were text in it.

I know that folk here in general say this practice is "not on", that it is
not "good design", but I really am curious. A lot of sites still do this.
How do they get this "thin black line" to display in Netscape?

Or have I missed something entirely???
