Web sites should not implement text resizing widgets–you know, those little buttons, usually an “A+” and “A-” that increase/descrease the size of the text on the site. The responsibility for providing this functionality lies with the browser, like the forward and back buttons.
Web designers/owners need to put forth more effort in teaching/guiding the user to using the browsers’ features for text resizing. Equally, the browsers themselves should make this feature more obvious and usable.
In addition, most sites I see that use resizing widgets are not very accessible; they seem to add this feature as a cheap replacement (bluff, excuse) for a genuinely accessible web site.
