I should work, and study the previous post answers, still, I'm also trying to understand this (no floats involved issue) :)
Please check the following test case: http://jsfiddle.net/NU3ZR/ This works, but I don't understand what is the role of left: 0; here. Obviously (or not), I tried to make: left: 50%; but the triangle don't get centered as expected. It only gets centered when we: 1) place that left: 0%; (and perhaps (not tested) to 100%); 2) define the background image to be horizontal positioned to 50%; Can anyone please care to clarify what's the role of left:0; here ? k. regards, mem ______________________________________________________________________ css-discuss [css-d@lists.css-discuss.org] http://www.css-discuss.org/mailman/listinfo/css-d List wiki/FAQ -- http://css-discuss.incutio.com/ List policies -- http://css-discuss.org/policies.html Supported by evolt.org -- http://www.evolt.org/help_support_evolt/
