Navigation
Navigation is no stranger to a front-end person. It can be said that navigation is one of the important elements and components of a website, which can facilitate users to find various functional services provided by the website.
<nav class="nabber navbar-default" role="navigation"><!--導(dǎo)航條、默認(rèn)樣式、role定義內(nèi)容是一個(gè)導(dǎo)航條--> <div class="container-fluid"><!--container居中固定寬度、c-f自適應(yīng)大小的導(dǎo)航條--> <div class="navbar-header"> <!--在響應(yīng)式瀏覽器寬度小于一定值時(shí)，顯示按鈕--> <button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target="#bs-example-navbar-collapse-1"> <span class="sr-only">Toggle navigation</span> <span class="icon-bar"></span> <span class="icon-bar"></span> <span class="icon-bar"></span> </button> <!--logo圖標(biāo)--> <a class="navbar-brand" href="#">Brand</a> </div> <div class="collapse navbar-collapse" id="bs-example-navbar-collapse-1"><!--包裹代碼，在寬度大于一定值時(shí)，button和此代碼是沒有作用的--> <!--導(dǎo)航條導(dǎo)航項(xiàng)目--> <ul class="nav navbar-nav"> <li class="active"><a href="#">a</a></li> <li><a href="#">a</a></li> </ul> </div> </div> </nav> .navbar-inverse:改變導(dǎo)航條的背景顏色 .container:居中顯示 固定導(dǎo)航條會(huì)遮蓋頁面內(nèi)容，解決辦法設(shè)置body的*padding-top*
Drop-down menu
Friends, please note that the drop-down menu component in the Bootstrap framework is an independent component.
<li class="dropdown"> <a href="#" class="dropdown-toggle" data-toggle="dropdown">下拉菜單<span class="caret"></span></a> <ul class="dropdown-menu" role="menu"> <li><a href="#">Action</a></li> <li><a href="#">Another action</a></li> <li><a href="#">Something else</a></li> <li class="divider"></li> <li><a href="#">linkkk/a></li> </ul> </li>
The data attribute API can use all Bootstrap plug-ins
Carousel ads (carousel)
<div id="carousel-example-generic" class="carousel slide" data-ride="carousel"> <!--底部導(dǎo)航點(diǎn)。。。--> <ol class="carousel-indicators"> <li data-target="#carousel-example-generic" data-slide-to="0"></li> <li data-target="#carousel-example-generic" data-slide-to="1" class="active"></li> <li data-target="#carousel-example-generic" data-slide-to="2"></li> </ol> <!--輪播廣告內(nèi)容--> <div class="carousel-inner" role="listbox"> <div class="item active"> <img src="…"> <div class="carousel-caption">……</div> </div> <div class="item active"> <img src="…"> <div class="carousel-caption">……</div> </div> </div> <!--左右箭頭--> <a class="left carousel-control" href="#carousel-example-generic" role="button" data-slide="prev"> <span class="glyphicon glyphicon-chevron-left"></span> <pan class="sr-only">previous</span> </a> <a class="right carousel-control" href="#carousel-example-generic" role="button" data-slide="next"> <span class="glyphicon glyphicon-chevron-right"></span> <pan class="sr-only">Next</span> </a> </div>
