thinking about a text-size feature for web-sites i'm more and more
conviced that this is usually implemented in a way which is *not* very
helpful for users who needs it:

* the default layout is often designed for tiny font-size and does not
scale perfectly
* the the font-size selctors are usually way too small to be easyly
recognized by people with low vision

i'm recommending this as good practice which provides much more
accessibility than the ordinary text-size features.

* select a readable font-size for your standard layout
* select relative lengths for font-size and other relevant design
elements (em is supported well enough these days)
* provide alternative stylesheets for your web site with a style
switcher: the alternative layout include not only bigger font-size,
but also a simpler, high-contrast design which can be more easily used
by people who have difficulties with the fancy standard layout.

Douglas Bowman's showed us an example of alterative
stylesheets providing more than bigger font-size. you can find it at

note: unfortunately this example IMHO fails in several usability
related ways: the menu name "prefs" might be suitable for native
english speakers but maybe not for an int'l community. the style
switcher offers too many options. i would vote for just one or two
alternative layouts. the labelling of the options could be improved

just my two cents...
