It looks like YUI Tooltips add the class yui-tt to all tooltips. You could style just your tooltips by using that as a common ancestor, i.e.
I load the configurator's style sheet (with the default skin (sam. Css) already included) in the head of my app followed by my own styles, so they are ready for immediate rendering. However as you mentioned, the YUI loader will subsequently override your styles.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
