Firefox 3 and Safari 5 have a menu item "Zoom Text Only". Reading with
Firefox, I find this very useful, since it commonly enlarges the text
without enlarging the images, and so gives less tendency to spill out of
a reasonable window width. It seems to work by zooming all dimensions
specified in 'em', 'ex', 'rem' and 'ch', or percentages thereof, with
the default font size at the start of the page being '1.0em'.
Therefore, it will zoom, if the author chooses, images sized by CSS
width/height in 'em' units; and column-widths can be made to zoom or
not, as required.
Obviously, when writing for ZTO, one needs to use the appropriate unit
for each dimensioned item. For example, the height of ordinary or
artificial buttons, if specified, should use ex units.
In many news/information sites, it works well for the main text but the
coding of headers and footers needs to be adjusted. Some fail badly.
It would be nice to be able to send to such sites the URLs of some pages
on how to do it; but I have found none such - are any known?
I've started writing, rather briefly, at
<http://www.merlyn.demon.co.uk/www-use1.htm#ZTO> - any comment?
FYI, CSS3, unlike any of my browsers, allows sizing by expressions with
mixed units.
