Hi, I need to calculate the line-height of an element. Unfortunately I cannot predict in which unit it will be set*** but I need to find out its px-value. If it is set in em or percent I can calculate it from the font-size, but that again could also be set in em or percent too.
So I'm wondering what's the right way to deal with this; Do I need to recursively traverse the DOM tree upwards until I find a line-height/font-size I can work with? What if none is set? I read the default font-size for IE/FF/Safari is 16px, but I'm actually not sure if that's true. Or is there another way I can't think of? Thanks, Lukas * if there's no other way I could base the calculation on px-, em- (and maybe percent)-values, but if I can avoid this that would be a bonus -- You received this message because you are subscribed to the Google Groups "Prototype & script.aculo.us" group.
