I was in the process of writing-up some inline CSS comments for my latest project, and I wanted to clarify/confirm a couple things about background positioning: 1. TRUE or FALSE: If you use a keyword for the horizontal value, and omit the vertical, the default vertical value is assumed to be "center". -- Note: The specs say 0% 0% is the initial value. <http://www.w3.org/TR/2007/CR-CSS21-20070719/colors.html#propdef-background-position> 2. TRUE or FALSE: For background positioning, the horizontal position must come first if one of the values is not a keyword. 3. TRUE or FALSE: If both values are keywords, the horizontal value *must* come first. Or is this just a matter preference and/or good coding practice? Sorry to resurrect an old thread... I just wanted to make sure my paraphrased comments are concise and correct. Many TIA!
