How change htmllabel background color width on xamarin?

I want to set the width of the htmllabel text background color in xamarin, but it covers the color as long as the text’s length. How can I cover the whole background?I want the red area to be as wide as the turquoise color in the back.

I’m sending html code from the service like this

Imd.DR = (d.OncelikID != (int)Sabitler.Oncelik.Yuksek) ? Fonksiyonlar.ModulDurumVer(d.DurumID ?? 0).Adi : "<span style="display:block; text-align:center; background-color:#ff0000; margin:auto; ">"
                                  + Fonksiyonlar.ModulDurumVer(d.DurumID ?? 0).Adi  + "<span>";

this is my xaml code in xamarin:

<htmlLabel:HtmlLabel Text="{Binding DR}" BackgroundColor="#b2e8e7" TextColor="Black" FontSize="10" HorizontalTextAlignment="Center" LineBreakMode="NoWrap"  Style="{DynamicResource ListItemTextStyle}"   />

Here is the entire xaml code:
