A brief discussion on how to customize the side navigation bar style in bootstrap

bootstrapThe built-in responsive navigation bar slides downwards. Sometimes it cannot meet the personalized needs. You need to make a side-sliding one similar to android drawerLayout. Menu, this is the bootstrap custom side-sliding menu I want to implement. I refer to the side-sliding of many official websites. The implementation methods are different, and the advantages and disadvantages are also very obvious. In order to only achieve a side-sliding effect on the homepage of some official websites, they use The owl.carousel sliding screen plug-in personally feels that it is making a mountain out of a molehill. The more professional name of this bootstrap side sliding menu is called mobile navigation bar. I also compare this name, which is more in line with the characteristics of bootstrap. Therefore, this article introduces an easier method that is easier for novices to accept.

bootstrap side navigation bar implementation principle

• side sliding bar positioning fixed

• Use The bootstrap responsiveness uses the tool class visible-sm visible-xs hidden-xs hidden-sm, etc. to adapt to different screens.

• The side-sliding effect of the side-sliding bar is not implemented using the jquery method. The css3 transforms attribute is used to move p, and the side sliding animation effect uses the css attribute transition

• Disadvantages: Use two sets of menus, one is the menu displayed on the PC screen , one set is a mobile phone navigation menu displayed on the mobile terminal. This shortcoming is relatively obvious. It generates irrelevant tags. The advantage is less code and is simple and easy to accept.

Click event switches side sliding

        $("#mobile-nav-taggle").click(function () {
            var mobileMenu = $("#mobile-menu");
            if (mobileMenu.hasClass("show-nav")) {
                setTimeout(function () {
                    mobileMenu.addClass("hide-nav").removeClass("show-nav");
                }, 100)
            }
            else {
                setTimeout(function (){
                    mobileMenu.addClass("show-nav").removeClass("hide-nav");
                }, 100)
            }
        })

It is not recommended to use two menu navigation bars. The shortcomings are obvious. In order to achieve the effect That's it, don't mind. In fact, it can also be achieved with a menu navigation bar. Try media and it can be achieved.
