Advantages of the CSS drop-down menu
Although pure CSS drop-down menus are less universal than those implemented by JavaScript, they are the development trend of WEB applications in the future, because mainstream browsers except IE6 have already supported them, IE6 has gone to the path of extinction. The advantage of the CSS drop-down menu is that it can run normally even if the browser disables JavaScript, and there will be no conflict when the page carries a large number of JavaScript scripts. In addition, learning to make CSS dynamic effects can make HTML writing more standard.
