Detailed explanation of how to customize the side navigation bar in bootstrap

This article will introduce to you how tobootstrapcustomize the side navigation bar. It has certain reference value. Friends in need can refer to it. I hope it will be helpful to everyone.

The responsive navigation bar that comes with bootstrap slides downwards. Sometimes it cannot meet the personalized needs. You need to make a side-sliding menu similar to android drawerLayout. This 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, owl.carousel is used. The 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

• The side sliding bar uses positioning fixed

• Use bootstrap responsiveness and use 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 does not use the jquery method. It uses the css3 transforms attribute to move p. 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, and the other is the mobile phone navigation menu displayed on the mobile terminal. This disadvantage is relatively obvious. It generates irrelevant labels. The advantage is that there is less code and is simple and easy to accept.

The layout of a navigation bar uses two navigation menus, one for PC and one for mobile phone. It is implemented using bootstrap responsiveness and tool class visible-xs visible-sm. Hide the switch button on the PC side; visible-lg visible-md realizes the display of the navigation bar on the PC side; visible-xs visible-sm realizes the display of the mobile navigation bar on the mobile phone.

* {margin:0;padding:0;} #mobile-menu {position:fixed;top:0;left:0;width:220px;height:100%;background-color:#373737;z-index:9999;} a:hover ,a:focus{text-decoration:none} .mobile-nav ul li a {color:gray;display:block;padding:1em 5%; border-top:1px solid #4f4f4f;border-bottom:1px solid #292929;transition:all 0.2s ease-out;cursor:pointer;#mobile-menu {position:fixed;top:0;left:0;width:220px;height:100%;background-color:#373737;z-index:9999;transition:all 0.3s ease-in;}} .mobile-nav ul li a:hover {background-color: #23A1F6;color: #ffffff;} .show-nav {transform:translateX(0);} .hide-nav {transform:translateX(-220px);} /*侧滑关键*/ .mobile-nav-taggle {height:35px;line-height:35px;width:35px;background-color:#23A1F6;color:#ffffff;display:inline-block;text-align:center;cursor:pointer} .nav.avbar-inverse{position:relative;} .nav-btn {position:absolute;right:20px;top:20px;}

It is worth noting that there are two properties of css3:

transform: rotation p, supports 2D or 3D rotation of elements. The attribute value translateX (X) is the distance of moving Xpx on the

transition: property duration timing-function delay;

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) } })
