The Missing manual says how much richer and better is Jquery than just js. Maybe, so I am trying it. Specifically I want to have a dialog box that displays on opening the page (achieved) and accepts and passes the single input string back to the calling line (failing). The js function "prompt" does exactly what I want except it is not pretty - but it is only one line. So my question is how to customize the dialog box, including changing the background, etc of the OK button and changing the text of the dialog box message depending on a condition? Thanks for any pointers you can give.

Right click on the dialogue to uncover the id/class of the dialogue. Then create the styles. Or add your own wrapper the output.

really need to see the page to offer something more tangible.
