Le 17/01/2013 20:38, "G�rard Talbot" a �crit : > CSS 2.1, section 4.3.2 Lengths states > > " > ex: the 'x-height' of the relevant font > (...) > The 'ex' unit is defined by the element's first available font. Yes, this is the key sentence. > The > exception is when 'ex' occurs in the value of the 'font-size' property, in > which case it refers to the 'ex' of the parent element. > " > http://www.w3.org/TR/CSS21/syndata.html#length-units css3-values already says � """ The exception is when [font-relative lengths] occur in the value of the �font-size� property itself, in which case they refer to the computed font metrics of the parent element (or the computed font metrics corresponding to the initial values of the �font� property, if the element has no parent). """ which I think is the same. (ex of the parent vs. x-height of the first font of the parent.) > This chunk of text is most likely what is missing in > CSS 3 Values and Units, section 5.1.1. Font-relative lengths: the �em�, > �ex�, �ch�, �rem� units > http://www.w3.org/TR/css3-values/#ex-unit Yes, that would be an adequate fix. -- Simon Sapin
