text auto resize as browser is resized (how do i)

Hi

As subject says i want the text in a text block to resize as the browser is resized so that you can still see all of the text (2 words)

i have a column within a row with a textblock inside that column, the column is set to take up whatever is left of the page width="*"

and here is the code for the text block could some one show me what to do with the code if this is even possible?

<Border Grid.Column="1" Grid.Row="0" CornerRadius="10" Background="LimeGreen" Margin="0,0,5,0">
                <TextBlock Text="Auswide Projects" Foreground="AliceBlue" FontSize="30" Margin="15" />

</Border>

 Cheers
