TIWTabControl - change the Tab style (CSS)

[jorgo2018]

Oh dear,

I tested following:

Code:

procedure TIWForm1.IWAppFormCreate(Sender: TObject);
begin
 with ExtraHeader do
 begin
   Add('<style type="text/css">');
   Add(' .IWTABCONTROL1CSS-ACTIVE-TAB {cursor: pointer; font-family: Arial, Sans-Serif, Verdana; font-weight: normal; font-style: normal; font-size: 16px; text-decoration: none;color: #000000; background-color:#F0F0F0; height: 24px; padding: 8px; border: 1px ; }');
   Add('</style>');
 end;
end;

Unfortunately, that did not work. It changed nothing to "IWTabControl1".
Does somebody has any idea?

Best regards
