interactive multimedia WEB

Question

how to make responsive WEB which contains so many games for children?

Answer 1

First you need an I/O back end system, giving the ability to store/retrieve your data easily. You must pay some time to it though before you start writing code. You could either store games as separate files in folders or as reference urls to original locations etc... Pick what's more convenient and flexible for your case. Then using technologies like AJAX retrieve all stored data (or parts of it depending your system) and display into a responsive grid page.
Tip for responsive : use media queries, percentances or viewport references.
(You could also scrape games from other popular sites...)
