Maybe these articles authors are the ones who should realize the problems (accessibility, usability) with their approach. > I realize it is > not that straightforward. The solution for me is straightforward. I set a font-size value for unstyled text in my browser. Then I intentionally, on purpose, set a minimal font-size value for all the designers and web site authors who, by ignorance or incompetence, do not understand that there are people who need bigger font size than fine print, who need more bigger than 11px, 12px and 13px. Such solution is straightforward to me. It can be applied to a bunch of media devices and non-media devices. In fact, we resort to such kind of straightforward solution every single day with communication and electronic devices (music, tv, radio, phone, etc.) (Did you know that there are now TV sets sold that allow to set a ceiling maximum level of acoustic pressure - say, 65dB - so that people are not annoyed by noisy, screaming TV advertisements?) With non-relative and non-standard font size, I often encounter overflow (and unexpected scrollbar, even in secondary windows), overlapping blocks and overlapping text in webpages often when font size is bigger in a webpage. It is because those authors do not sufficiently, correctly understand that *_their_* preferred font size may not be everyone else's preferred font size. > Here's a summary of the approach we have taken: > > * We do set a default font size, You forgot an importantissimo detail here. You set a default font-size in pixels, not in a relative font size unit. " Do not specify the font-size in pt, or other absolute length units for screen stylesheets. They render inconsistently across platforms and can't be resized by the User Agent (e.g browser). " W3C Quality Assurance Tips for Webmasters http://www.w3.org/QA/Tips/font-size So, on top of overriding the default, initial browser (and any UA) standard font size, it is also a "frozen" one, a rigid one, an unflexible one for browsers like IE 6, IE 7 and IE 8. Vincent Flanders and Jakob Nielsen and many others have denounced this for many years as a bad design practice. > but it's not as small as what the > most common font size seems to be. "Not as small" is a relative perspective. Some people may be really thinking instead "it's not as big as what the default, standard browser font size is". Who is responsible for choosing a screen resolution for their monitor screen? > This choice will not satisfy all users, but I believe it is a > reasonable compromise. It's not a reasonable compromise to me. It is going against all normal, sensible accessibility recommendation. I personally had to fight very hard with Microsoft so that Microsoft would fix several related bugs regarding font-size and resizing text size, in particular the EM extreme font resizing bug: http://www.gtalbot.org/BrowserBugsSection/MSIE7Bugs/#bug79 I have incontrovertible proof that some accessibility feature in IE regarding font size will not work as expected and, in fact, turn out to truncate content, crop content, clip content and make a webpage less accessible because of a [declarative] too small font-size: http://www.gtalbot.org/BrowserBugsSection/MSIE8Bugs/#bug207 " We were able to reproduce the issue. The problem also reproduces with IE 7. The table in the connect site wasn't designed to handle larger fonts. (...)

Will it satisfy the algorithm proposed in Techniques For Accessibility Evaluation And Repair Tools Checkpoint 2.2 - Ensure that foreground and background color combinations provide sufficient contrast when viewed by someone having color deficits or when viewed on a black and white screen http://www.w3.org/TR/AERT#color-contrast and discussed in Juicy Studio's Luminosity Colour Contrast Ratio Analyser http://juicystudio.com/services/colourcontrast.php#contrast which is based on that algorithm to begin with? > Thanks for sending comments. I welcome the feedback, > > _ Ian I do not understand why this font-size: 13px at all, in particular at W3C. Why take a chance of annoying people with a sub-standard, under default-standard font size? Personally I have never met a person saying that font-size on my website is too big and, if I ever do, then I'll calmly explain to him/her that he can choose his font-size preference at will and he can choose the optimal screen resolution for his viewing needs ... just like he can adjust the volume level of his TV.
