I have my website made by custom script. I want to show the light box type window when a user lands on my site. It will have plus one, facebook like, facebook share, twitter tweet. I want this script to share or like the page on which he user has came and shared. And if the user has already done this before he will not be shown this window. there should be a close button too for skipping this sharing or liking. Will you please help me to make it?
