Course Introduction：The reason for building navigation using Bootstrap is that it provides a powerful, mobile-first design approach. 1) Bootstrap's mesh system and pre-built components make creating responsive layouts efficient. 2) Its huge community and detailed documentation provide strong support. 3) Use Bootstrap to quickly prototype the responsive navigation bar. 4) By adding the fixed-top class and adjusting the page fill, the problem of blocking content on the top navigation bar can be solved. 5) The drop-down menu in the navigation bar can effectively organize navigation projects and improve user experience. 6) Use CDN to optimize Bootstrap file loading to improve performance. 7) Ensure accessibility of the navigation bar and enhance disability by using ARIA attributes

Course 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
