Building Mega Menus with Flexbox
Article Introduction：Core points
Flexbox is a CSS layout model that allows developers to create complex UIs without relying on redundant CSS and JavaScript tricks. It uses a linear layout model, making it easier to layout content horizontally or vertically without spacing calculations.
Flexbox can be used to create websites with giant navigation menus. This layout model allows creating simple navigation bars, single drop-down menu segments, and limiting single drop-down menu segments to three columns. The Flex layout is responsive to elements within the container, reducing the need for media queries.
The final mega menu created in this tutorial is not fully responsive. The main menu bar will be displayed on a smaller screen, but the giant menu will not be available, only the top links are available

How to fix Bootstrap navbar z-index issue?
Article Introduction：Bootstrap navigation bar z-index issues are usually caused by improperly setting the cascaded context or position attribute. Common scenarios and solutions are as follows: 1. When the drop-down menu is blocked, set non-static positioning of the .dropdown parent and improve the z-index of .dropdown-menu to 1060; 2. When the fixed-top navigation bar is blocked, set the z-index of .navbar.fixed-top to 1030; 3. When multiple navigation elements interfere, unify the planning levels such as the main navigation 1030 and the floating toolbar 1040, and avoid abuse of z-index:9999. During troubleshooting, check whether the position attribute is effective.

Bootstrap navbar accessibility best practices
Article Introduction：To improve the accessibility of the Bootstrap navigation bar, you need to pay attention to the following three points: 1. Use semantic labels and ARIA attributes to clarify the navigation structure and interaction status, such as wrapping the navigation bar and adding aria-label, and setting properties such as role and aria-expanded for the drop-down menu; 2. Ensure smooth navigation of the keyboard, all links and buttons can be focused through the Tab key, and support Enter or Space key operations; 3. Provide sufficient color contrast and icon text description, and use aria-label or .visually-hidden class to assist screen readers to identify content, thereby comprehensively improving the user experience of all users.

How to create a double row navbar in Bootstrap?
Article Introduction：The core method of implementing a dual-row navigation bar in Bootstrap is to combine structures and style adjustments. 1. Use nested containers to build a double-row structure, use two independent .navbars or .containers to place the top and bottom navigation content respectively, the first line places secondary information such as language switching and contact information, and the second line is used as the main menu; 2. Use Flex layout to merge into a container, set d-flexflex-column through the outer div to achieve vertical stacking, and manage styles and widths uniformly; 3. Optimization details include controlling spacing, responsive hiding the first line content, style isolation, and color matching coordination.

Why is Popper.js needed for Bootstrap navbar?
Article Introduction：Bootstrap's navigation bar component relies on Popper.js because its drop-down menus, tooltips, and pop-ups cannot be handled by itself. Popper is responsible for dynamically computing and adjusting the positions of these floating elements to ensure that they are aligned correctly with the trigger elements. For example: 1) The drop-down menu will automatically flip position according to the space; 2) The tooltips will remain visible when the window is adjusted or scrolled; 3) The mobile terminal adapts to avoid content overflowing the screen. Compared with pure CSS solutions, Popper has the ability to intelligently adjust the runtime, supports modifier compatibility and cross-browser compatibility, greatly reducing the need for manual encoding. Therefore, Popper is a key dependency for achieving precise positioning under complex layouts.
