A Project of Magic HTML Client Edges

Magic HTML Client Edges - Part 3

Introduction
In this part of the series, we effectively carry out a project. The project deals with a web page.
The aim of the project is that when you move your mouse pointer to the edge of the web page,
a pane with a calculator or some other useful tool should scroll into the page; you can do
whatever you want to do with the tool; when you click on the BODY of the page, outside the
pane, the pane scrolls back into the edge. The fundamentals for the project are in the previous
parts of the series.

I have done a lot of detail explanation in the previous parts of the series. Explanations in this
and the next part of the series will be summarized where possible.

The tool for the pane in our project is a calculator. The details of the calculator will not be
given. In the next part of the series, we shall look at the complete code of the project.

Note: If you cannot see the code or if you think anything is missing (broken link, image
absent), just contact me at forchatrans@yahoo.com. That is, contact me for the slightest
problem you have about what you are reading.

The Project
After going through the basics we are now in the position to come up with the technical
requirements. We now know what is possible and what is not possible so far as the DOM
JavaScript and HTML are concerned. Before we look at the technical requirements let us look
again at the user requirements again:
