I'm using this code to include my public style sheets:
<!DOCTYPE html>
<html>
<head>
<title>Laravel</title>
<link rel="stylesheet" href="{{ asset('css/c_bootstrap.css') }}">
<link rel="stylesheet" href="{{ asset('css/style_x.css') }}" />
<link rel="stylesheet" href="{{ asset('css/sb-admin.css') }}" />
</head>
<body>
<!-- navbar -->
@include ('layout.navbar')
<div class="container">
<div class="content">
@yield('content')
</div>
</div>
</body>
</html>
when i click on it i get this:

so it really looks like it works. However, it's just the error CSS from Laravel error page:

so what's the mistake I'm doing here?
my folder:
|- public
|-|--- assets
|-|---|--- css
|-|---|---|--- c_bootstrap.css
|-|---|---|--- s.css
|-|---|---|--- sb-admin.css

assetsfolder spelling is wrong.asset('assets/css/c_bootstrap.css')something like that for other files too?c_bootstrap.csspage as html?
