Saya sedang mengusahakan permainan solitaire klondike dan saya mencipta menu yang dipaparkan di bahagian atas halaman. Pada komputer riba dan komputer saya mahu kelihatan seperti menu biasa, memandangkan ramai pemain sudah biasa dengan menu sedemikian, tetapi pada peranti mudah alih, saya mahu item menu mudah diklik.

<div class="menu-bar" id="menuBar"></div>

Berikut ialah gaya css untuk menu biasa:

        body {
            padding: 0;
            margin: 0;
        }

        /* Basic menu styling for desktop */
        .menu-bar {
            display: flex;
            background-color: #333;
            padding: 10px;
            justify-content: flex-start;
            /* Align menu items to the left */

            font-family: Arial, Helvetica, sans-serif
        }

        .menu-item {
            color: white;
            padding: 10px;
            cursor: pointer;
            position: relative;
            text-align: center;
            flex: 0;
            display: flex;
            /* Align icon and text on the same line */
            align-items: center;
            justify-content: center;
            white-space: nowrap;
        }

        .menu-item {
            text-align: left;
        }

        .menu-item i {
            font-size: 1.5rem;
            margin-right: 8px;
            /* Space between icon and text */
        }

        .menu-item .shortcut,
        .submenu-item .shortcut {
            color: #999;
        }

        .menu-item .shortcut {
            display: none;
            /* too ugly on main items */
        }


        .submenu {
            display: none;
            position: absolute;
            background-color: #444;
            top: 40px;
            left: 0;
            width: 150px;
        }

        .submenu-item {
            padding: 10px;
            color: white;
        }

        .submenu-item:hover {
            background-color: #666;
        }

        .menu-item.active .submenu {
            display: block;
        }

Untuk menjadikan menu bertindak secara berbeza pada peranti mudah alih kami akan menggunakan pertanyaan media:

        /* Mobile styles */
        @media (max-width: 768px) {
            .menu-bar {
                flex-direction: column;
                position: relative;
                display: grid;
                /* Grid layout for mobile */
                grid-template-columns: repeat(auto-fit, minmax(100px, 1fr));
                /* Evenly divide menu items into columns */
                gap: 10px;
            }

            .menu-item {
                padding: 15px 5px;
                display: block;
                /* Stack icon and text vertically on mobile */
                white-space: normal;
            }

            .menu-item {
                text-align: center;
            }

            .menu-item i {
                font-size: 2rem;
                /* Larger icon for mobile */
                margin-right: 0;
                /* Remove margin on mobile */
                display: block;
                /* Icon on a separate line */
                text-align: center;
            }

            .menu-item .shortcut {
                display: none;
                /* Hide shortcuts on mobile */
            }

            .submenu {
                position: static;
                display: none;
                width: 100%;
                background-color: #333;
                top: 0;
                left: 0;
                z-index: 10;
            }

            .menu-item.active .submenu {
                display: block;
            }

            .menu-bar.active .menu-item {
                display: none;
            }

            .menu-bar.active .menu-item.active {
                display: block;
            }

            .submenu .close-btn {
                color: white;
                padding: 10px;
                cursor: pointer;
                text-align: center;
                background-color: #444;
            }

            .submenu .close-btn:hover {
                background-color: #666;
            }
        }

dan akhirnya javascript:

        const menuData = [
            {
                icon: "fa-solid fa-gamepad", // Icon for "New Game..."
                icon_text: "?", // Emoji for game controller
                name: "New Game...",
                shortcut: "",
                submenu: {
                    items: [
                        {
                            name: "Restart",
                            icon: "fa-solid fa-undo-alt", // Icon for "Restart"
                            icon_text: "?", // Emoji for restart
                            shortcut: "Ctrl+N"
                        },
                        {

                            icon_text: "??", // Emoji for start/play
                            shortcut: ""
                        }
                    ]
                }
            },
            {
                icon: "fa-solid fa-cog", // Icon for "Settings..."
                name: "Settings...",
                icon_text: "??", // Emoji for settings
                shortcut: "Ctrl+S",
                submenu: null
            },
            {
