Subject: Re: [cgmo-webcgm] convert-to-absolute [was: Re[2]: [cgmo-webcgm] Style properties]
Hi Lofton, Please note that section 5.4.1.3 still has a TO DO. I'm not sure we have the concept of Used Values in WebCGM. I couldn't come up with an example. The CSS 2.1 text is this: "Computed values can be relative to each other; for example a width could be set as a percentage, which is dependent on the containing block's width. The used value is the result of taking the computed value and resolving these dependencies into a final absolute value used for the actual layout." Can you think of a scenario that would demonstrate we do have Used Values? In general, I think this sub issue is a very minor one and should be ignored for now. We may want to adjust the wording, but that can be done later (in my opinion). -- Benoit mailto:benoit@itedo.com Tuesday, May 17, 2005, 7:40:13 PM, Lofton wrote: LH> At 02:58 PM 5/17/2005 -0400, Benoit Bezaire wrote: >>[...] >> >>LH> Btw, do we have a contradiction within 5.4?
