Thanks for your reply.
The situation is very common on the Web now.
My 17" monitor is from NEC years ago, is razor
sharp and rock solid, and I see no great reason
to take time out to change from it. Besides,
as another comment in this thread noted, laptops
also have relatively small screens! So do tablets
and phones!
I know nothing about using Google's blogspot.
For the Web site I'm building, all screens are
just 800 pixels wide, and all my fonts are nice
and large. So, on a big screen, could have
a 'pile' of dozens of such windows each offset
a little, and on a small screen could still see
the full width easily without using horizontal
scroll bars.
How'd I do that? I'm a beginner at HTML but
just stuffed in 800 px some places, and got
800 pixels. If in a browser I shrink a window to less than
800 pixels, then I get horizontal scroll bars.
Broadly it's easy to assume that there it's reasonable
to use lots of space vertically and let the user do
a vertical scroll but try to minimize space
used horizontally so that a user doesn't have to
do a horizontal scroll just to read the text.
In some cases, I just highlight the text, copy
it to the clipboard, pull it into my favorite
editor, and flow the text to, say, 60 characters
a line.
My view is, in reading, 40 characters per
line has some advantages in eye movement
in reading,
60 characters per line
is plenty, 72 is almost too many, 80
is about the upper limit, and over 100 is
too often a problem and, really, for
easy eye movement in reading,
too much.
Heck, even when newspapers had sheet
sizes big enough to cover a table top,
they still kept way down the number
of characters per line.
But I can't tell the world how to design
Web pages. If some people want, say, 300
characters per line and 20 characters per
inch on the screen horizontally, then so be it.
