Subject: Text spacers - What do you use?
I'm generating an HTML report page using Perl. I'm reticent to use a table
for formatting the page. What do most folks use for text spacers? As I see it, I can use a javascript loop to generate a passed value of Or, should I generate the space within Perl? -- You must Sign in before you can post messages.

Then you forgot the most important rule: be lazy. In Perl you could
write the above as: print ( ( ' ' x 12, "\n" ) x 4 ); > The above will serve So... get lazy :-D > only to further my blindness. :-) >>print "<br>\n" for 1 .. 100000; # outer space Don't > I'd replace <br> with . :-) > But, this is what I'm think of.
