Now for my education can anyone explain to me why in modifying a tag in
the HyperText Markup (HTML) document source code of the output file of
the form MyFile.html to include " "
that the display of such a MyFile.html in both the Konqueror-4.6.00 and
Mozilla Firefox-6.0.2 Web browsers produced what looked like only about
two blank spaces instead of the six blank spaces commanded?
"A space" is not a unit of width except when using a monospace
(typewriter) typeface. In normal variable-width typefaces "a space" is a
quantity set by the type designer appropriate for a default word-space.
You cannot use multiple spaces and expect them to multiply widthwise
except when using a monospace typeface.
In HTML, multiple normal space-characters always get collapsed to a single
space (except in monospace formats like the pre element type). In
variable-width typefaces, multiple non-breaking spaces will produce a
small increase in white-space but certainly not "six blank spaces" because
there is no such concept as "six blank spaces" because a space is not a
unit of measurement.
A non-breaking space is what it says: it replaces a space where you want a
single space to appear, but the line must never be broken at that point.
Using multiple instances of them to try and align material is usually
pointless because they will create different results in different browsers
and different typefaces.
If you need to align material, use a table; or if you want to force a
blank space of a known width, use a span element and set its style to use
margin-right of the required dimension, eg
<span style="margin-right:6em"></span>
Some browsers may elide this, so you might have to use
<span style="margin-right:5em"> </span>
