Hey again :)
Could you tell me how to make the sub-menupoints also appearing slowly in transition?
By the way could you recommend a list or a collection of all those css-codes? That I can learn for myself and try different things?
The support documentation lists a number of great resources to get started with CSS: http://en.support.wordpress.com/custom-design/editing-css/#css-help. Please, let me know if you have any questions!
Hope you'll find it fun to learn CSS and tinker with the styles in your site :D
