I have done a few test with background-size that works in Safari 3 (beta) that could be showing what I have explained above. http://css-class.com/test/css/colorsbackgrounds/background-size.htm http://css-class.com/test/css/colorsbackgrounds/background-size2.htm http://css-class.com/test/css/colorsbackgrounds/background-size2.htm Widening or narrowing the window will reveal gaps or bands in the background image at certain intervals. This is more prominent on the horizontal axis and is more apparent when done slowly. All three test behave differently in where the gaps appear or the amount of times a gap appears. The first test I can count over 30 gaps appearing when widening the viewpoint from 800px up to 1200px ever so slowly. These test could also just show a bug in Safari 3. Alan http://css-class.com/
