- by Matt Joiner

The following table element in the "center" div causes the contents in the "left" divs to be offset by several pixels from the top (8 in my browser). Adding some text prior to the table removes this offset. Why? How do I stop this from happening without requiring a "dummy" line of text before my table? <html> <head> <style…

Confusion about inheritance
