I manage to create masterpage on sharepoint 2019 but i failing to att css on the master page, it does not render my css on the master page . My css on my html file look as follows:
<!--MS:<SharePoint:CssRegistration Name="Themable/corev15.css" runat="server">-->
<!--ME:</SharePoint:CssRegistration>-->
<!--SPM:<SharePoint:CssRegistration ID="CustomCSS" name="<% $SPUrl:~SiteCollection/_catalogs/masterpage/Bob/style.css%>" After="corev15.css" runat="server"/>-->
<!--SPM:<SharePoint:CssRegistration ID="CustomCSS1" name="<% $SPUrl:~SiteCollection/_catalogs/masterpage/Bob/grid.css%>" After="corev15.css" runat="server"/>-->
It always uses corev15.css, it does not load my custom css at all .
Thank you
