Greetings, When a text colour is specified at a particular level of specificity, without specifying a background-colour, the CSS validator rightly objects, advising that it's good practice to specify both at a given level of specificity, or neither. This is, of course, good advice and the reasons relating to the effect of the cascade (with different levels of specificity and with stylesheets from different sources) are quite widely known. However, if one specifies a background-color of 'transparent', the validator stops complaining (if I'm not mistaken). I beg to suggest that specifying a background-color of 'transparent' along with an explicitly-specified text colour, can lead to cascading problems which are very similar in nature to those resulting from not specifying a background-color at all. A chance discussion on de.comm.infosystems.www.authoring.misc has just confirmed that I am not alone in considering this to be a problem. May I suggest that the validator should give out analogous warnings in this situation (i.e text colour specified explicitly and background specified by 'transparent')? While composing this note, it occurs to me that difficulties of a similar nature might arise if an explicit background-color is specified while the text colour is specified as 'inherit'. best regards
