@rasoul_rezazadeh your view method should look like
public function view(Article $article) {
return view('articles.show',compact('article'))
}
you don't need to put id in your link as if you typehint the model, the view method will know to use your primary key.
href="/articledetails/{{$article}}"
as for why your page doesn't display its css correctly, that's a different problem and is more than likely due to css link not starting with a forward slash to make it load css from top level directory.
