It doesn't correlate to the visitor's preferred/default size, so randomly, typically negatively, impacts legibility, accessibility and usability. Likewise, its use for sizing text containers is also inappropriate, since line lengths in words vary according to text size and become too long or short according to the actual appropriate size in the rendering UA. Used for sizing text px is totally rude, since it absolutely disregards UA defaults - just like absolute units do. Truly responsive design is necessarily medium/ex/em/rem/100%-based. It can't be px- or absolute-based. -- "The wise are known for their understanding, and pleasant words are persuasive." Proverbs 16:21 (New Living Translation) Team OS/2 ** Reg.
