The following example shows how to use the BaselineAlignment property to align text within a containing box (in this case, a Paragraph).
<Page xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
<FlowDocumentReader>
<FlowDocument ColumnWidth="800">
<Paragraph Background="Blue">
<!-- The large text forces a large containing box size for the paragraph.
The smaller text fragments align themselves vertically within this
box according to their BaselineAlignment values. -->
<Span FontSize="40">Baseline:</Span>
<Span BaselineAlignment="Baseline">Baseline</Span>
<Span BaselineAlignment="Top">Top</Span>
<Span BaselineAlignment="Bottom">Bottom</Span>
<Span BaselineAlignment="Center">Center</Span>
</Paragraph>
<Paragraph Background="Green">
<!-- The BaselineAlignment values of Subscript and Superscript below
force the containing box to be larger then it normally would be. -->
<Span FontSize="40">Baseline:</Span>
<Span BaselineAlignment="Subscript">Subscript</Span>
<Span BaselineAlignment="Baseline">Baseline</Span>
<Span BaselineAlignment="Superscript">Superscript</Span>
</Paragraph>
<Paragraph Background="Yellow" LineHeight="60" LineStackingStrategy="BlockLineHeight">
<!-- A deliberate BlockLineHeight stacking strategy change, to show the difference between Top/TextTop
and Bottom/TextBottom-->
<Span FontSize="40" BaselineAlignment="Baseline">Baseline:</Span>
<Span BaselineAlignment="Top">Top</Span>
<Span BaselineAlignment="TextTop">TextTop</Span>
<Span BaselineAlignment="Bottom">Bottom</Span>
<Span BaselineAlignment="TextBottom">TextBottom</Span>
</Paragraph>
</FlowDocument>
</FlowDocumentReader>
</Page>
The following illustration shows the result of the code above.
