I lose my bootstrap styles when passing variable (get) to route->Controller->View in Laravel 5.4. here is my code-

header.blade.php->
<a href="">

    web.php->
    Route::get('/news/{id}', 'NewsController@view_news');

    NewsController.php->
    public function view_news($id) {
            $category_info = Category::where('publication_status', 1)->get();
            $category_product = Product::where('id', $id)->get();
            $data = array();
            $data['header_content'] = view('Front_End.includes.header', ['all_published_category' => $category_info]);
            $data['home_slider']= view('Front_End.slider.home_slider');
            $data['main_content'] = view('Front_End.category.category_content', ['category_product' => $category_product]);
            $data['footer_content']= view('Front_End.includes.footer');
            return view('Front_End.master')->with($data);
        }
