Can't navigate the page in laravel project

I have created addnewemployee.blade.php in the views folder. In routes, I have mentioned

 Route::get('/addnewemployee', function() {
        return view('addnewemployee');  
    });

As well as I have given the path in my enter code herehome page like

   <a class="btn cus-button" href=""> Add New </a>

Once I click the add new button, 'addnewemployee' is added with my URL but it shows 404 not found. Can anyone please help me?
