I want to add a version no to global.css like global.css?ver=1600. I looked in header include template. But there is a variable {$stylesheet}.
I could not understand the purpose of it !!
But why you want to include this to css stylesheet ?
because, I've set cache of my site through .htaccess for one week, and now whenever I change something, the users will see the old style, then they have to refresh with ctrl+f5 to see the changes
Bump still need to find out!
