An StackLayout class shows a single element at a time..
<p>The horizontal position of the shown element is determined by the layout's
<code>horizontalAlign</code> property.</p>
<p>The vertical position of the shown element is determined by the layout's
<code>verticalAlign</code> property.</p>
<p>The width of each element is calculated according to the following rules,
listed in their respective order of precedence (element's minimum width and
maximum width are always respected):</p>
<ul>
<li>If <code>horizontalAlign</code> is <code>"justify"</code>,
then set the element's width to the container width.</li>
<li>If <code>horizontalAlign</code> is <code>"contentJustify"</code>,
then set the element's width to the maximum between the container's width
and all elements' preferred width.</li>
<li>If the element's <code>percentWidth</code> is set, then calculate the element's
width as a percentage of the container's width.</li>
<li>Set the element's width to its preferred width.</li>
</ul>
<p>The height of each element is calculated according to the following rules,
listed in their respective order of precedence (element's minimum height and
maximum height are always respected):</p>
<ul>
<li>If the <code>verticalAlign</code> property is <code>"justify"</code>,
then set the element's height to the container height.</li>
<li>If the <code>verticalAlign</code> property is <code>"contentJustify"</code>,
then set the element's height to the maximum between the container's height
and all elements' preferred height.</li>
<li>If the element's <code>percentHeight</code> property is set,
then calculate the element's height as a percentage of the container's height.</li>
<li>Set the element's height to its preferred height.</li>

The horizontal alignment of layout elements.
<p>If the value is <code>"left"</code>, <code>"right"</code>, or <code>"center"</code> then the
layout element is aligned relative to the container's <code>contentWidth</code> property.</p>
<p>If the value is <code>"contentJustify"</code>, then the layout element's actual

The <code>contentWidth</code> of the container is the width of the largest layout element.

The vertical alignment of layout elements.
<p>If the value is <code>"bottom"</code>, <code>"middle"</code>,
or <code>"top"</code> then the layout elements are aligned relative
to the container's <code>contentHeight</code> property.</p>
<p>If the value is <code>"contentJustify"</code> then the actual
height of the layout element is set to
the container's <code>contentHeight</code> property.
The content height of the container is the height of the largest layout element.
If all layout elements are smaller than the height of the container,
then set the height of all the layout elements to the height of the container.</p>
