[TuniDev-HUB]

Please, can you help me to find where is my mistake (Thank's)
here is my code :
var minCssSetting = new CssSettings()
{
CommentMode = CssComment.Important,
MinifyExpressions = true,
OutputMode = OutputMode.SingleLine,
TermSemicolons = false,
};

pipeline.AddCssBundle("site-Ar.min.css",

"_Css/StyleImport-Ar.css",
"Assets/css/tiny-slider.css",
"Assets/css/nouislider.css",
"Assets/css/theme.css",
"Assets/css/cartzilla-icon.css",
"_Css/StyleCartzilla.css",
"_Css/StyleCartzilla-Menu.css",
"_Css/StyleCartzilla-Divers.css",
"_Css/StyleCartzilla-Product.css",
"_Css/StyleNotification.css",
"_Css/StyleReview.css",
"_Css/StyleDivider.css",
"_Css/StylePage.css",
"_Css/croppie.min.css",
"_Css/StyleFont-Ar.css"

).MinifyCss(minCssSetting);

Well, I solve it my problem by remove the StyleImport-Ar.css, because it contain

        @charset "UTF-8";
        @import url("https://fonts.googleapis.com/css2?family=Cairo:wght@300;400;500;700&display=swap");

I think there a special case you need to check it,

Keep going, you doing a good job
