工具类

Bootstrap提供了十几个辅助工具类，包括边框、清除浮动、颜色、display、浮动、定位、文本对齐等。在开发中可以直接应用这些类，让开发更加快捷和简单。

1.边框

Bootstrap提供了边框类样式，可以快速地添加、删除边框，也可以设置边框的颜色，边框的圆角。
Bootstrap给元素边框设置了.border基类，如果想要加其他的样式，都要在.border的基础上去添加。边框的样式可以组合使用，多个样式之间只需使用空格隔开即可。

给元素添加border类可以添加四个方向的边框。也可以设置某一个方向上的边框。

例：添加边框示例

<!DOCTYPE html>
<html>
	<head>
		<meta charset="UTF-8">
		<title></title>
		<meta name="viewport" content="width=device-width,initial-scale=1,minimum-scale=1,maximum-scale=1,user-scalable=no" />
		<link rel="stylesheet" type="text/css" href="../css/bootstrap.min.css"/>
		<script src="../js/jquery.min.js" type="text/javascript" charset="utf-8"></script>
		<script src="../js/bootstrap.min.js" type="text/javascript" charset="utf-8"></script>
		<style type="text/css">
			div{
				width: 100px;
				height: 100px;
				margin-right: 20px;
				float: left;
				background-color: #eee;
			}
		</style>
	</head>
	<body class="container">
		<h3>添加边框</h3>
		<div class="border border-success">四个边框</div>
		<div class="border-top border-success">上边框</div>
		<div class="border-right border-success">右边框</div>
		<div class="border-bottom border-success">下边框</div>
		<div class="border-left border-success">左边框</div>
	</body>
</html>

结果图：

给元素添加border-0类可以移除这四个方向的所有边框。也可以单独移除某一个方向上的边框。

例：删除边框

<!DOCTYPE html>
<html>
	<head>
		<meta charset="UTF-8">
		<title></title>
		<meta name="viewport" content="width=device-width,initial-scale=1,minimum-scale=1,maximum-scale=1,user-scalable=no" />
		<link rel="stylesheet" type="text/css" href="../css/bootstrap.min.css"/>
		<script src="../js/jquery.min.js" type="text/javascript" charset="utf-8"></script>
		<script src="../js/bootstrap.min.js" type="text/javascript" charset="utf-8"></script>
		<style type="text/css">
			div{
				width: 100px;
				height: 100px;
				margin-right: 20px;
				float: left;
				background-color: #eee;
			}
		</style>
	</head>
	<body class="container">
		<h3>删除边框</h3>
		<div class="border border-0 border-success">无边框</div>
		<div class="border border-top-0 border-success">无上边框</div>
		<div class="border border-right-0 border-success">无右边框</div>
		<div class="border border-bottom-0 border-success">无下边框</div>
		<div class="border border-left-0 border-success">无左边框</div>
	</body>
</html>

结果图：

考虑到Bootstrap提供的.border类默认边框颜色是淡灰色，在实际开发中如果想要修改边框颜色，可以使用.border-*来设置想要的场景颜色。“*”的取值有: primary、secondary、success、danger、warning.info、ligit、dark、white

例：边框颜色示例

<!DOCTYPE html>
<html>
	<head>
		<meta charset="UTF-8">
		<title></title>
		<meta name="viewport" content="width=device-width,initial-scale=1,minimum-scale=1,maximum-scale=1,user-scalable=no" />
		<link rel="stylesheet" type="text/css" href="../css/bootstrap.min.css"/>
		<script src="../js/jquery.min.js" type="text/javascript" charset="utf-8"></script>
		<script src="../js/bootstrap.min.js" type="text/javascript" charset="utf-8"></script>
		<style type="text/css">
			div{
				width: 100px;
				height: 100px;
				margin-right: 20px;
				margin-bottom: 10px;
				float: left;
				background-color: #ddd;
			}
		</style>
	</head>
	<body class="container">
		<h3>边框颜色</h3>
		<div class="border border-primary"></div>
		<div class="border border-secondary"></div>
		<div class="border border-success"></div>
		<div class="border border-danger"></div>
		<div class="border border-warning"></div>
		<div class="border border-info"></div>
		<div class="border border-light"></div>
		<div class="border border-dark"></div>
		<div class="border border-white"></div>
	</body>
</html>

结果图：

给元素添加rounder类可以实现圆角边框的效果。也可以单独指定某一个方向上的圆角边框。
例：圆角边框示例

<!DOCTYPE html>
<html>
	<head>
		<meta charset="UTF-8">
		<title></title>
		<meta name="viewport" content="width=device-width,initial-scale=1,minimum-scale=1,maximum-scale=1,user-scalable=no" />
		<link rel="stylesheet" type="text/css" href="../css/bootstrap.min.css"/>
		<script src="../js/jquery.min.js" type="text/javascript" charset="utf-8"></script>
		<script src="../js/bootstrap.min.js" type="text/javascript" charset="utf-8"></script>
		<style type="text/css">
			div{
				width: 100px;
				height: 100px;
				margin-right: 20px;
				margin-bottom: 10px;
				float: left;
				background-color: #ddd;
			}
		</style>
	</head>
	<body class="container">
		<h3>圆角边框</h3>
		<div class="border border-primary rounded"></div>
		<div class="border border-primary rounded-0"></div>
		<div class="border border-primary rounded-top"></div>
		<div class="border border-primary rounded-right"></div>
		<div class="border border-primary rounded-bottom"></div>
		<div class="border border-primary rounded-left"></div>
		<div class="border border-primary rounded-circle"></div>
		<div class="border border-primary rounded-pill"></div>
	</body>
</html>

结果图：

2.清除浮动

通过添加.clearfix工具类，可以快速轻松地清除容器中浮动的内容。为父元素添加.clearfix可以很容易地清除浮动。
例：

<!DOCTYPE html>
<html>
	<head>
		<meta charset="UTF-8">
		<title></title>
		<meta name="viewport" content="width=device-width,initial-scale=1,minimum-scale=1,maximum-scale=1,user-scalable=no" />
		<link rel="stylesheet" type="text/css" href="../css/bootstrap.min.css"/>
		<script src="../js/jquery.min.js" type="text/javascript" charset="utf-8"></script>
		<script src="../js/bootstrap.min.js" type="text/javascript" charset="utf-8"></script>
	</head>
	<body class="container">
		<div class="border clearfix">
			<div class="bg-info p-3 float-left">向左浮动（float）的div</div>
			<div class="bg-info p-3 float-right">向右浮动（float）的div</div>
		</div>
	</body>
</html>

结果图：

3.颜色

可以使用.text-*将文本设置为指定的颜色。
.text-light和.text-white在白色背景下看不清楚，可以设置一个黑色的背景来辅助查看效果。
可以使用.text-white-数值和.text-black-数值来设置颜色的透明度效果，后面的数值表示的是透明度。如.text-white-50和.text-black-50，分别表示透明度为0.5的白色或黑色文本。

例：文本颜色示例

<!DOCTYPE html>
<html>
	<head>
		<meta charset="UTF-8">
		<title></title>
		<meta name="viewport" content="width=device-width,initial-scale=1,minimum-scale=1,maximum-scale=1,user-scalable=no" />
		<link rel="stylesheet" type="text/css" href="../css/bootstrap.min.css"/>
		<script src="../js/jquery.min.js" type="text/javascript" charset="utf-8"></script>
		<script src="../js/bootstrap.min.js" type="text/javascript" charset="utf-8"></script>
	</head>
	<body class="container">
