Hi Jon--

Would this be considered a usability issue, then? 


I would imagine that some people with low vision would want to increase font size without enlarging the rest of the page. Fixed font sizes would make that impossible and could make the page more difficult to use because of scrolling.

If I understand the question correctly, I would also disagree with the stance. <smile>

Not under WCAG 2 level A or AA but  It would likely but not necessarily fail under level AAA SC 1.4.8. 

SC 1.4.4 allows for user agent zoom to compensate for use of pixel.   So the only time use of pixels would fail this SC is if it wasn't accessibility supported by the technology stack.  

Personally I don't totally agree with this stance because zoom requires the user to scroll horizontally. 

Under 1.4.8. It would have to zoom without horizontal scroll - this is less likely to be handles correctly when pixels are used.

Hi, 

I have others questions like the one last week about opening new
      window without prior notice for the working group members.

I will do each one on a separate thread for more clarity.

Do you consider using pixel font size for text in a  as a WCAG
      success criteria failure ? (example : 
<p class="myfont">some dummy text</p>
      .myfont{font-size:12px;}

If yes to witch success criteria ?
      I'm especially interested to have your opinion one the 1.4.4 SC
      because I don't see anything saying it's a failure except on text
      based form controls (witch isn't the case in my example) so for me
      it isn't.

And you what do you think ?

Regards,
