The spec actually defines what happens with fonts when you don't have a defined computed style: # If the computed values are undefined for a particular case (e.g. because # the font style source object is not an element or is not being # rendered), then the relative keywords must be interpreted relative to # the normal-weight 10px sans-serif default. This is needed for text rendering in Workers, if nothing else. -- Ian Hickson U+1047E )\._.,--....,'``. fL http://ln.hixie.ch/ U+263A /, _.. \ _\ ;`._ ,.
