I do not agree. Any webpage can be styled to honor the preferred font-size of the user. The font size should ideally be left to the user to decide. So web authors shouldn't set it in webpage. Several people have explained this before. Felix Miata, Stephen Poley, Oliver Reichenstein, etc Web Browser Default Text Size http://fm.no-ip.com/Auth/defaultsize.html http://fm.no-ip.com/Auth/wauth1.html and http://fm.no-ip.com/Auth/auth.html by Felix Miata The Wrong Size Fonts Or why not to over-ride the reader's font size by Stephen Poley http://sbpoley.home.xs4all.nl/webmatters/fontsize.html and Adjusting your text size by Stephen Poley http://sbpoley.home.xs4all.nl/main/adjust.html " This website, like all well-designed sites, uses the text size defined in your browser. This means you can set it to whatever size is most convenient for you. " The 100% Easy-2-Read Standard by Oliver Reichenstein (excellent read) http://informationarchitects.net/blog/100e2r/ " This paragraph (and the heading and subheading above) is in your browser's default font (typeface) and default (base) text size. Web pages often try to override this size for their body text. The better-designed sites won't do this " Accessible Web design http://www.syntacticweb.co.uk/calib.htm ------ Regarding high contrast, it is the responsibility of the web author to make all of its webpages comply with standards of color contrast/brightness as given by WAI and WCAG. There are tools and tutorials on all this: 10 colour contrast checking tools to improve the accessibility of your design http://www.456bereastreet.com/archive/200709/10_colour_contrast_checking_tools_to_improve_the_accessibility_of_your_design/ Effective Color Contrast http://www.lighthouse.org/accessibility/design/accessible-print-design/effective-color-contrast ------------ My position is: by default, the persistent, the preferred and the alternate [1] stylesheets should always respect and honor the user's font-size as set in his UA and they should always have sufficient, effective color contrast promoting readability/legibility.
