Laravel pagination without style

Below is my code: ` @foreach($posts as $post)

                        <tr>
                            <th></th>                            
                            <td></td>
                            <td> </td>
                            <td></td>
                            <td>
                                <a href="" class="btn btn-default btn-sm">View</a>
                                <a href="" class="btn btn-delete btn-sm">Edit</a>                                  
                            </td>
                        </tr>

                    @endforeach
                </tbody>
            </table>

            <div class="text-center">
                
            </div>`

And below is the code in controller:

public function index()
{
    $posts = Post::orderBy('id', 'desc')->paginate(5);

    return view('posts.index')->withPosts($posts);
}

In spite of this, i do not get proper styling! Bootstrap styles not applied. See the image.
