            <h3>Test case:</h3>
            <ul>
                <li>
                    Blue div has 400px width, dynamic height, and position: relative.
                </li>
                <li>
                    Inside blue div there are 3 other div with height: 40px (and has some bottom margin..)<br>
                    the height of the blue div expands with the green divs inside..
                </li>
                <li>
                    Yellow div has position absolute (and positioned in the top left corner of the blue div)<br>
                    it's height set to 100%<br>
                    the height of the yellow div now equals with the height of the blue div
                </li>
                <li>
                    Red div is inserted into the yellow div, and it's height set to 100%
                </li>
            </ul>

            <h3>Problem:</h3>
            <p>
                The height of the red div <strong>should equals</strong> to the height of the blue (and yellow) div.<br>
                It works right with Opera 9.2, Firefox 2, Camino 1.0.4 and Internet Explorer 7.
            </p>

            <h3>Workaround:</h3>
            <p>
                If you set position absolute to the red div, it's height will expands along with the blue div.
            </p>

                div.style.color = color;
                div.appendChild(document.createTextNode(message));
                result.appendChild(div);
            }
