Floating box in the window

[nagalenoj]

Dear friends,

    Right now, I am doing a project. In that, I have a need to open a box when clicking a button.

 

    I want a box like window. I tried it with div tag by making the visibility true and false. But, the div tag acquires some space in the web page. I want that to be appeared similar to another window.

 

For your reference, have a look in the following url to get the feel, click the Member sign in button in the url, a small login window(box) will open. How to do that.?

Kindly, give me some suggestions.

You have to use z-index and position: absolute if I remember correctly.
