A Top Navigation Menu for a Klondike Solitaire Games, That Changes Aspect on Mobile Devices

I'm working on a klondike solitaire game and I created a menu that is displayed on the top of the page. On laptops and computers I want to look like regular menus, considering many players are used to such menus, but on mobile devices, I wanted the menu items to be easy to click.

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

Here is the css style for the regular menu:

        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;
        }

To make the menu act differently on mobile devices we are going to use media queries:

        /* 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;
            }
        }

and finally the javascript:

        const menuData = [
            {
                icon: "fa-solid fa-gamepad", // Icon for "New Game..."

                shortcut: "",
                submenu: {
                    items: [
                        {

                            shortcut: ""
                        }
                    ]
                }
            },
            {

                name: "Settings...",
