bootstrap简介:
? 简单灵活可用于架构流行的用户界面和交互接口的html、css、javascript工具集。
? 基于html5、css3的bootstrap,具有大量的诱人特性:友好的学习曲线,卓越的兼容性,响应式设计,12列格网,样式向导文档。
? 自定义JQuery插件,完整的类库,基于Less等。
bootstrap模板为使IE6、7、8版本(IE9以下版本)浏览器兼容html5新增的标签,引入下面代码文件即可。 <script src="https://oss.maxcdn.com/libs/html5shiv/3.7.0/html5shiv.js"></script> 使IE6、7、8版本浏览器兼容css3样式,引入下面代码: <script src="https://oss.maxcdn.com/libs/respond.js/1.4.2/respond.min.js"></script>
标题:①.h1=36px,h2=30px,h3=24px,h4=18px,h5=14px、h6=12px
②<small>标签来制作副标题
强调内容: class="lead" 另外还有元素标签:<small>、<strong>、<em>、<cite>、<b>、<em>、<i>给文本做突出样式处理。
.lead { margin-bottom: 20px; font-size: 16px; font-weight: 200; line-height: 1.4; } @media (min-width: 768px) {/*大中型浏览器字体稍大*/ .lead { font-size: 21px; } } b,strong { font-weight: bold; /*文本加粗*/ } small,.small { font-size: 85%; /*标准字体的85%,也就是14px * 0.85px,差不多12px*/ } cite { font-style: normal; }
.text-muted:提示,使用浅灰色(#999) .text-primary:主要,使用蓝色(#428bca) .text-success:成功,使用浅绿色(#3c763d) .text-info:通知信息,使用浅蓝色(#31708f) .text-warning:警告,使用黄色(#8a6d3b) .text-danger:危险,使用褐色(#a94442)
文本对齐风格:.text-left:左对齐 .text-center:居中对齐 .text-right:右对齐 .text-justify:两端对齐
.text-left { text-align: left; } .text-right { text-align: right; } .text-center { text-align: center; } .text-justify { text-align: justify; }
列表:
①无序列表、有序列表<ul>、<ol>
ul, ol { margin-top: 0; margin-bottom: 10px; } ul ul, ol ul, ul ol, ol ol { margin-bottom: 0; }
②去点列表 类名".list-unstyled"
.list-unstyled { padding-left: 0; list-style: none; }
③内联列表 类名“.list-inline” :把垂直列表换成水平列表,而且去掉项目符号(编号),保持水平显示
.list-inline { padding-left: 0; margin-left: -5px; list-style: none; } .list-inline > li { display: inline-block; padding-right: 5px; padding-left: 5px; }
④定义列表 <dl><dt><dd>
dl { margin-top: 0; margin-bottom: 20px; } dt, dd { line-height: 1.42857143; } dt { font-weight: bold; } dd { margin-left: 0; }
⑤水平定义列表 类名“.dl-horizontal”:针对<dt><dd>
@media (min-width: 768px) { .dl-horizontal dt { float: left; width: 160px; overflow: hidden; clear: left; text-align: right; text-overflow: ellipsis; white-space: nowrap; } .dl-horizontal dd { margin-left: 180px; } }
代码:
1:①、使用<code></code>来显示单行内联代码:<code><code></code>
②、使用<pre></pre>来显示多行块代码
③、使用<kbd></kbd>来显示用户输入代码:比如<kbd>ctrl+x</kbd>
2:类名“.pre-scrollable”:高度超出340px,就会在Y轴出现滚动条。
.pre-scrollable { max-height: 340px; overflow-y: scroll; }
表格:
表格行的类:<tr>元素中添加上表对应的类名,就能达到你自己需要的效果
1.基础表格 类名“.table”:后面各种表格都要加上这个类名。
2.斑马线表格 类名“table-striped”
.table-striped > tbody > tr:nth-child(odd) > td, .table-striped > tbody > tr:nth-child(odd) > th { background-color: #f9f9f9; }
3.带边框的表格 类名“.table-bordered”
.table-bordered { border: 1px solid #ddd;/*整个表格设置边框*/ } .table-bordered > thead > tr > th, .table-bordered > tbody > tr > th, .table-bordered > tfoot > tr > th, .table-bordered > thead > tr > td, .table-bordered > tbody > tr > td, .table-bordered > tfoot > tr > td { border: 1px solid #ddd; /*每个单元格设置边框*/ } .table-bordered > thead > tr > th, .table-bordered > thead > tr > td { border-bottom-width: 2px;/*表头底部边框*/ }
4.鼠标悬浮高亮的表格 类名“table-hover”
.table-hover > tbody > tr:hover > td, .table-hover > tbody > tr:hover > th { background-color: #f5f5f5; }
5.紧凑型表格 类名“table-condensed”
.table-condensed > thead > tr > th, .table-condensed > tbody > tr > th, .table-condensed > tfoot > tr > th, .table-condensed > thead > tr > td, .table-condensed > tbody > tr > td, .table-condensed > tfoot > tr > td { padding: 5px; }
6.响应式表格 类名“.table-responsive”:当你的浏览器可视区域小于768px时,表格底部会出现水平滚动条。
Bootstrap提供了一个容器,并且此容器设置类名“.table-responsive”,此容器就具有响应式效果,然后将<table class="table">置于这个容器当中,这样表格也就具有响应式效果 <div class="table-responsive"> <table class="table table-bordered"> … </table> </div>
1.基础表单 :对于基础表单,Bootstrap并未对其做太多的定制性效果设计,仅仅对表单内的fieldset、legend、label标签进行了定制。
fieldset { min-width: 0; padding: 0; margin: 0; border: 0; } legend { display: block; width: 100%; padding: 0; margin-bottom: 20px; font-size: 21px; line-height: inherit; color: #333; border: 0; border-bottom: 1px solid #e5e5e5; } label { display: inline-block; margin-bottom: 5px; font-weight: bold; }
2.水平表单 类名“form-horizontal”
.form-horizontal .control-label, .form-horizontal .radio, .form-horizontal .checkbox, .form-horizontal .radio-inline, .form-horizontal .checkbox-inline { padding-top: 7px; margin-top: 0; margin-bottom: 0; } .form-horizontal .radio, .form-horizontal .checkbox { min-height: 27px; } .form-horizontal .form-group { margin-right: -15px; margin-left: -15px; } .form-horizontal .form-control-static { padding-top: 7px; } @media (min-width: 768px) { .form-horizontal .control-label { text-align: right; } } .form-horizontal .has-feedback .form-control-feedback { top: 0; right: 15px; }
3.内联表单 类名“form-inline”
<form class="form-inline" role="form"> <div class="form-group"> <label class="sr-only" for="exampleInputEmail2">邮箱</label> <input type="email" class="form-control" id="exampleInputEmail2" placeholder="请输入你的邮箱地址"> </div> <div class="form-group"> <label class="sr-only" for="exampleInputPassword2">密码</label> <input type="password" class="form-control" id="exampleInputPassword2" placeholder="请输入你的邮箱密码"> </div> <div class="checkbox"> <label> <input type="checkbox">记住密码 </label> </div> <button type="submit" class="btnbtn-default">进入邮箱</button> </form> <-- .sr-only:给残障人员用的 --> <-- .sr-only { position: absolute; width: 1px; height: 1px; padding: 0; margin: -1px; overflow: hidden; clip: rect(0, 0, 0, 0); border: 0; } -->
表单控件
1.输入框input: 为了让控件在各种表单风格中样式不出错,需要添加类名“form-control”,下面各个表单控件都能加。
<!doctype html> <html lang="en"> <head> <meta charset="UTF-8"> <title>表单控件——输入框input</title> <link rel="stylesheet" href="//netdna.bootstrapcdn.com/bootstrap/3.1.1/css/bootstrap.min.css"> </head> <body> <form role="form"> <div class="form-group"> <input type="email" class="form-control" placeholder="Enter email"> <input type="text" class="form-control" placeholder="Enter Username"> </div> </form> </body> </html>
type类型:text button checkbox date datetime datetime-local img file hidden month number password radio range reset search submit tel time url week hidden
2.下拉选择框select:多行选择设置multiple属性的值为multiple
<form> <div class="form-group"> <select multiple class="form-control"> //如果是下拉框就不要加multiple <option>踢足球</option> <option>游泳</option> <option>慢跑</option> <option>跳舞</option> </select> </div> </form>
3.文本域textarea:添加了类名“form-control”类名,则无需设置cols属性。
<form role="form"> <div class="form-group"> <textarea class="form-control" rows="3"></textarea> </div> </form>
4.复选框checkbox和单选择按钮radio:水平排列加类名“checkbox-inline”||类名“radio-inline”
<!doctype html> <html lang="en"> <head> <meta charset="UTF-8"> <title>表单控件——表单控件大小</title> <link rel="stylesheet" href="//netdna.bootstrapcdn.com/bootstrap/3.1.1/css/bootstrap.min.css"> </head> <body> <form role="form"> <h3>案例1</h3> <div class="checkbox"> <label> <input type="checkbox" value=""> 记住密码 </label> </div> <div class="radio"> //如果要水平class=“radio-inline” <label> <input type="radio" name="optionsRadios" id="optionsRadios1" value="love" checked> 喜欢 </label> </div> <div class="radio"> //如果要水平class=“radio-inline” <label> <input type="radio" name="optionsRadios" id="optionsRadios2" value="hate"> 不喜欢 </label> </div> </form> </body> </html>
.radio, .checkbox { display: block; min-height: 20px; padding-left: 20px; margin-top: 10px; margin-bottom: 10px; } .radio label, .checkbox label { display: inline; font-weight: normal; cursor: pointer; } .radio input[type="radio"], .radio-inline input[type="radio"], .checkbox input[type="checkbox"], .checkbox-inline input[type="checkbox"] { float: left; margin-left: -20px; } .radio + .radio, .checkbox + .checkbox { margin-top: -5px; }
.radio-inline, .checkbox-inline { display: inline-block; padding-left: 20px; margin-bottom: 0; font-weight: normal; vertical-align: middle; cursor: pointer; } .radio-inline + .radio-inline, .checkbox-inline + .checkbox-inline { margin-top: 0; margin-left: 10px; }
5.控件大小:类名input-sm:让控件比正常大小更小;类名input-lg:让控件比正常大小更大;宽度配合Bootstrap的网格系统
.input-sm { height: 30px; padding: 5px 10px; font-size: 12px; line-height: 1.5; border-radius: 3px; } select.input-sm { height: 30px; line-height: 30px; } textarea.input-sm, select[multiple].input-sm { height: auto; } .input-lg { height: 46px; padding: 10px 16px; font-size: 18px; line-height: 1.33; border-radius: 6px; } select.input-lg { height: 46px; line-height: 46px; } textarea.input-lg, select[multiple].input-lg { height: auto; }
6.表单控件状态(焦点状态):类名form-control
.form-control:focus { border-color: #66afe9; outline: 0; -webkit-box-shadow: inset 0 1px 1pxrgba(0,0,0,.075), 0 0 8px rgba(102, 175, 233, .6); box-shadow: inset 0 1px 1pxrgba(0,0,0,.075), 0 0 8px rgba(102, 175, 233, .6); }
7.表单控件状态(禁用状态):form-control别忘记加①在需要禁用的表单控件上加上“disabled”;②fieldset设置了disabled属性,整个域都将处于被禁用状态。
.form-control[disabled], .form-control[readonly], fieldset[disabled] .form-control { cursor: not-allowed; background-color: #eee; opacity: 1; }
8.表单控件状态(验证状态):1、.has-warning:警告状态(黄色) 2、.has-error:错误状态(红色) 3、.has-success:成功状态(绿色)
:需要类名has-feedback + <span class="glyphicon glyphicon-remove form-control-feedback"></span>
9.表单提示信息:"help-block"
.help-block { display: block; margin-top: 5px; margin-bottom: 10px; color: #737373; }
按钮
建议使用button或a标签来制作按钮
1.基本按钮:类名“btn”
.btn { display: inline-block; padding: 6px 12px; margin-bottom: 0; font-size: 14px; font-weight: normal; line-height: 1.42857143; text-align: center; white-space: nowrap; vertical-align: middle; cursor: pointer; -webkit-user-select: none; -moz-user-select: none; -ms-user-select: none; user-select: none; background-image: none; border: 1px solid transparent; border-radius: 4px; }
2.默认按钮: 类名“btn” + 类名“btn-default”
.btn-default { color: #333; background-color: #fff; border-color: #ccc; }
4.按钮大小: .btn-lg:大型按钮 .btn-sm:小型按钮 .btn-cs:超小型按钮
.btn-lg, .btn-group-lg> .btn { padding: 10px 16px; font-size: 18px; line-height: 1.33; border-radius: 6px; } .btn-sm, .btn-group-sm> .btn { padding: 5px 10px; font-size: 12px; line-height: 1.5; border-radius: 3px; } .btn-xs, .btn-group-xs> .btn { padding: 1px 5px; font-size: 12px; line-height: 1.5; border-radius: 3px; }
5.块状按钮: 类名“btn-block”
6.禁用状态: 使用disabled类或disabled属性
图像 1.img-responsive:响应式图片,主要针对于响应式设计 2.img-rounded:圆角图片 3.img-circle:圆形图片 4.img-thumbnail:缩略图片
img { vertical-align: middle; } .img-responsive, .thumbnail>img, .thumbnail a >img, .carousel-inner > .item >img, .carousel-inner > .item > a >img { display: block; max-width: 100%; height: auto; } .img-rounded { border-radius: 6px; } .img-thumbnail { display: inline-block; max-width: 100%; height: auto; padding: 4px; line-height: 1.42857143; background-color: #fff; border: 1px solid #ddd; border-radius: 4px; -webkit-transition: all .2s ease-in-out; transition: all .2s ease-in-out; } .img-circle { border-radius: 50%; }

按钮(按钮工具栏) 类名btn-toolbar
.btn-group-lg:大按钮组 .btn-group-sm:小按钮组 .btn-group-xs:超小按钮组
<div class="btn-toolbar"> <div class="btn-group"> … </div> <div class="btn-group"> … </div> <div class="btn-group"> … </div> <div class="btn-group"> … </div> </div> 源码 .btn-toolbar { margin-left: -5px; } .btn-toolbar .btn-group, .btn-toolbar .input-group { float: left; } .btn-toolbar > .btn, .btn-toolbar > .btn-group, .btn-toolbar > .input-group { margin-left: 5px; } 注意在”btn-toolbar”上清除浮动。 .btn-toolbar:before, .btn-toolbar:after{ display: table; content: " "; } .btn-toolbar:after{ clear: both; }
按钮(嵌套分组): “btn-group”和普通的按钮放在同一级。
<div class="btn-group"> <button class="btnbtn-default" type="button">首页</button> <button class="btnbtn-default" type="button">产品展示</button> <button class="btnbtn-default" type="button">案例分析</button> <button class="btnbtn-default" type="button">联系我们</button> <div class="btn-group"> <button class="btnbtn-default dropdown-toggle" data-toggle="dropdown" type="button">关于我们<span class="caret"></span></button> <ul class="dropdown-menu"> <li><a href="##">公司简介</a></li> <li><a href="##">企业文化</a></li> <li><a href="##">组织结构</a></li> <li><a href="##">客服服务</a></li> </ul> </div> </div> 源码 .btn-group > .btn-group { float: left; } .btn-group > .btn-group:not(:first-child):not(:last-child) > .btn { border-radius: 0; } .btn-group > .btn-group:first-child> .btn:last-child, .btn-group > .btn-group:first-child> .dropdown-toggle { border-top-right-radius: 0; border-bottom-right-radius: 0; } .btn-group > .btn-group:last-child> .btn:first-child { border-top-left-radius: 0; border-bottom-left-radius: 0; } .btn-group .dropdown-toggle:active, .btn-group.open .dropdown-toggle { outline: 0; } .btn-group > .btn + .dropdown-toggle { padding-right: 8px; padding-left: 8px; } .btn-group > .btn-lg + .dropdown-toggle { padding-right: 12px; padding-left: 12px; } .btn-group.open .dropdown-toggle { -webkit-box-shadow: inset 0 3px 5px rgba(0, 0, 0, .125); box-shadow: inset 0 3px 5px rgba(0, 0, 0, .125); } .btn-group.open .dropdown-toggle.btn-link { -webkit-box-shadow: none; box-shadow: none; }
按钮(垂直分组):类名“btn-group-vertical”
<div class="btn-group-vertical"> <button class="btnbtn-default" type="button">首页</button> <button class="btnbtn-default" type="button">产品展示</button> <button class="btnbtn-default" type="button">案例分析</button> <button class="btnbtn-default" type="button">联系我们</button> <div class="btn-group"> <button class="btn btn-default dropdown-toggle" data-toggle="dropdown" type="button">关于我们<span class="caret"></span></button> <ul class="dropdown-menu"> <li><a href="##">公司简介</a></li> <li><a href="##">企业文化</a></li> <li><a href="##">组织结构</a></li> <li><a href="##">客服服务</a></li> </ul> </div> </div> 源码 .btn-group-vertical > .btn, .btn-group-vertical > .btn-group, .btn-group-vertical > .btn-group > .btn { display: block; float: none; width: 100%; max-width: 100%; } .btn-group-vertical > .btn-group > .btn { float: none; } .btn-group-vertical > .btn + .btn, .btn-group-vertical > .btn + .btn-group, .btn-group-vertical > .btn-group + .btn, .btn-group-vertical > .btn-group + .btn-group { margin-top: -1px; margin-left: 0; } .btn-group-vertical > .btn:not(:first-child):not(:last-child) { border-radius: 0; } .btn-group-vertical > .btn:first-child:not(:last-child) { border-top-right-radius: 4px; border-bottom-right-radius: 0; border-bottom-left-radius: 0; } .btn-group-vertical > .btn:last-child:not(:first-child) { border-top-left-radius: 0; border-top-right-radius: 0; border-bottom-left-radius: 4px; } .btn-group-vertical > .btn-group:not(:first-child):not(:last-child) > .btn { border-radius: 0; } .btn-group-vertical > .btn-group:first-child:not(:last-child) > .btn:last-child, .btn-group-vertical > .btn-group:first-child:not(:last-child) > .dropdown-toggle { border-bottom-right-radius: 0; border-bottom-left-radius: 0; } .btn-group-vertical > .btn-group:last-child:not(:first-child) > .btn:first-child { border-top-left-radius: 0; border-top-right-radius: 0;
按钮(等分按钮) “btn-group-justified”类名
特别声明:在制作等分按钮组时,请尽量使用<a>标签元素来制作按钮,因为使用<button>标签元素时,使用display:table在部分浏览器下支持并不友好。 <div class="btn-wrap"> <div class="btn-group btn-group-justified"> <a class="btnbtn-default" href="#">首页</a> <a class="btnbtn-default" href="#">产品展示</a> <a class="btnbtn-default" href="#">案例分析</a> <a class="btnbtn-default" href="#">联系我们</a> </div> </div> 源码 .btn-group-justified { display: table; width: 100%; table-layout: fixed; border-collapse: separate; } .btn-group-justified > .btn, .btn-group-justified > .btn-group { display: table-cell; float: none; width: 1%; } .btn-group-justified > .btn-group .btn { width: 100%; }
按钮下拉菜单
按钮下拉菜单从外观上看和下拉菜单效果基本上是一样的;简单点说就是点击一个按钮,会显示隐藏的下拉菜单 <div class="btn-group"> <button class="btn btn-default dropdown-toggle" data-toggle="dropdown" type="button">按钮下拉菜单<span class="caret"></span></button> <ul class="dropdown-menu"> <li><a href="##">按钮下拉菜单项</a></li> <li><a href="##">按钮下拉菜单项</a></li> <li><a href="##">按钮下拉菜单项</a></li> <li><a href="##">按钮下拉菜单项</a></li> </ul> </div> 源码: .btn-group .dropdown-toggle:active, .btn-group.open .dropdown-toggle { outline: 0; } .btn-group > .btn + .dropdown-toggle { padding-right: 8px; padding-left: 8px; } .btn-group > .btn-lg + .dropdown-toggle { padding-right: 12px; padding-left: 12px; } .btn-group.open .dropdown-toggle { -webkit-box-shadow: inset 0 3px 5px rgba(0, 0, 0, .125); box-shadow: inset 0 3px 5px rgba(0, 0, 0, .125); } .btn-group.open .dropdown-toggle.btn-link { -webkit-box-shadow: none; box-shadow: none; }
按钮的向下向上三角形 类名.dropup向上
<div class="btn-group dropup"> <button class="btn btn-default dropdown-toggle" data-toggle="dropdown" type="button">按钮下拉菜单<span class="caret"></span></button> <ul class="dropdown-menu"> <li><a href="##">按钮下拉菜单项</a></li> <li><a href="##">按钮下拉菜单项</a></li> <li><a href="##">按钮下拉菜单项</a></li> <li><a href="##">按钮下拉菜单项</a></li> </ul> </div> 解析 按钮的向下三角形,我们是通过在<button>标签中添加一个“<span>”标签元素,并且命名为“caret”: <button class="btn btn-default dropdown-toggle" data-toggle="dropdown" type="button">按钮下拉菜单<span class="caret"></span></button> 源码: .caret { //生成三角形 display: inline-block; width: 0; height: 0; margin-left: 2px; vertical-align: middle; border-top: 4px solid; border-right: 4px solid transparent; border-left: 4px solid transparent; } 在按钮中的三角形“caret”做了一定的样式处理: .btn .caret { margin-left: 0; } .btn-lg .caret { border-width: 5px 5px 0; border-bottom-width: 0; } .dropup .btn-lg .caret { border-width: 0 5px 5px; } 向上三角与向下三角的区别:其实就是改变了一个border-bottom的值。 .dropup .caret, .navbar-fixed-bottom .dropdown .caret { content: ""; border-top: 0; border-bottom: 4px solid; }
