I want to apply custom CSS to a team site Seattle master page in SharePoint 2013. Is there any way available to do this without activating publishing feature?
I tried adding
<link> tag in masterpage, but it doesn't take any effect.
Upload your css to the master page gallery or site assest folder, you can create a folder in your master page gallery and upload your CSS file there either manually or using a module in Visual Studio. Then you can refernce it using :
<SharePoint:CssRegistration name="<% $SPUrl:~sitecollection/_catalogs/masterpage/YourSiteFolder/YourCSSFile.css %>" runat="server" after="corev15.css"/>
