I'm not sure if there's an official (W3C?) recommendation,
have said that absolute widths should precedence over relative widths.
My logic for this is that if you want something say roughly a 1/3rd
the page you could use a table/column width of say "30%", which is
more of a 'I want it to look narrower than the rest', whereas if you
specifically want a navigation bar or something to be a precise size
you'd use something like <td width=200> or something.
Thus, exact sizes are generally chosen because that's exactly
want, whereas percentage/relative sizes are chosen because you're not
/that/ fussed but you want it roughly that size relative to the
browser window or rest of the page etc.
Yes, I agree with you entirely. But the problem occurs when get a
conflict between the percentages, the fixed widths and the width of
the window. For example you might have a window which is 800px wide,
and a page containing a table of width 100% i.e. 800px, with a row of
three cells of widths 200, 50% and 30%. This implies that 200 is
equivalent to 20% so the table width should be 1000 and not 800. I
haven't even considered borders, margins, cellpadding and cellspacing!
What is the browser meant to do? It could scale everything down by
80%, it could just scale down the 50% and 30% columns, or it could
extend the page outside the window so you have to scroll it.
Then what happens if you have subsequent rows which conflict with the
first row or which impose further constraints, such as a fixed width
cell in column 3? What happens if you have an image inside a table
cell with an explicit width that exceeds the implicit or explicit
column width? I think that absolute image widths take precedence over
column or table widths.
