Hi Antonella,
Thank you very much of your kind reply I will try to implement what you have been suggested me. Another question the example site (http://nicolas-bussiere.fr/) how can i make the same animation effects between pages going back and forth if you click first link of the slide it takes you another page with very smooth slide animation on next page if you click the downarrow link page will go up and new page will popup from bottom very impressive animation.
Please if you could give me any idea how to accomplish this kinda animation with jquery either css3.
I will appreciate your help.
Many thanks in advance
