I'm new in web develop. I want to realize a function that when I click the link "click to see sample colors", it will popup a page like the picture to show all my sample colors. But I don't know what kind of technics to use to do it. I have search on w3schools. But the popup window or popup boxes using javaScript is not what I want.
Could you help me to realize the effect using a simple way?
Thank you very much!!
