<issue_to_address>
The new .btn-outline-info selector may not cover all color variants.

If you plan to use other variants like 'primary' or 'secondary', consider adding similar rules for them to maintain consistency.

         .Build();

     private string? GetButtonItemClassString(SelectedItem item) => CssBuilder.Default("btn")
-        .AddClass($"active bg-{Color.ToDescriptionString()}", CurrentValueAsString == item.Value)
+        .AddClass($"btn-outline-{Color.ToDescriptionString()}")
+        .AddClass("active", CurrentValueAsString == item.Value)
</code_context>

<issue_to_address>
The removal of the bg-{Color} class may affect background coloring for active buttons.

If you still want a background color for active buttons, consider adding the appropriate styling, as only the 'active' class is now applied.
