It is required to display a window with information, but not what the standard window provides in JS, I do not need to open a new browser window, I need to open a window with my own interface directly on this page (on many sites, various warnings work this way). For example, registration and login on the site now.ru - it uses exactly those windows that I need to implement.

    This, if the set of windows is limited, it is not difficult to write yourself, but since there are some good ready-made solutions, it is better to use them.

    It is specifically used there, as I quickly looked at, jQuery UI . There are other frameworks with windows. For example, Prototype UI . Although, as it seems to me, it is more suitable for applications =) Or now - MooLego UI .

    There are examples everywhere where you can see how it works.
