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>

.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,

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;
}

}
下拉菜单(对齐方式):在“dropdown-menu”上添加一个“pull-right”或者“dropdown-menu-right”类名
<div class="dropdown">
<button class="btn btn-default dropdown-toggle" type="button" id="dropdownMenu1" data-toggle="dropdown">
下拉菜单
<span class="caret"></span>
</button>
<ul class="dropdown-menu pull-right" role="menu" aria-labelledby="dropdownMenu1">
…
</ul>
</div>
源码
.dropdown-menu.pull-right {
right: 0;
left: auto;
}
.dropdown-menu-right {
right: 0;
left: auto;
}
同时一定要为.dropdown添加float:leftcss样式。
.dropdown{
float: left;
}
下拉菜单(菜单项状态):class="active"、class="disabled"
<div class="dropdown">
<button class="btn btn-default dropdown-toggle" type="button" id="dropdownMenu1" data-toggle="dropdown">
下拉菜单
<span class="caret"></span>
</button>
<ul class="dropdown-menu" role="menu" aria-labelledby="dropdownMenu1">
<li role="presentation" class="active"><a role="menuitem" tabindex="-1" href="#">下拉菜单项</a></li>
….
<li role="presentation" class="disabled"><a role="menuitem" tabindex="-1" href="#">下拉菜单项</a></li>

1、默认所有按钮都有圆角
2、除第一个按钮和最后一个按钮(下拉按钮除外),其他的按钮都取消圆角效果
3、第一个按钮只留左上角和左下角是圆角
4、最后一个按钮只留右上角和右下角是圆角
对应的源码如下:
.btn-group > .btn:not(:first-child):not(:last-child):not(.dropdown-toggle) {
border-radius: 0;
}
.btn-group > .btn:first-child {
margin-left: 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 {

.btn-group-justified > .btn-group .btn {

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;
}
