有没有人知道如何将下面的 XAML 输出实现为 HTML5 和 CSS3:
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="100" />
<RowDefinition Height="33" />
<RowDefinition Height="29" />
<RowDefinition Height="*"/>
<RowDefinition Height="75" />
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="98" />
<ColumnDefinition Width="*" />
<ColumnDefinition Width="98" />
</Grid.ColumnDefinitions>
<Border x:Name="header" Grid.Row="0" Grid.Column="1"/>
<Border x:Name="mainNav" Grid.Row="1" Grid.Column="1"/>
<Border x:Name="secondNav" Grid.Row="2" Grid.Column="1"/>
<Border x:Name="body" Grid.Row="3" Grid.Column="1"/>
<Border x:Name="footer" Grid.Row="4" Grid.Column="1"/>
</Grid>
谢谢
