Bootstrap 图片
Bootstrap 对图片的支持。Bootstrap 提供了三个可对图片应用简单样式的 class：
请看下面的实例演示：
<!DOCTYPE html><html><head> <title>Bootstrap 实例 - 图像</title> <link href="http://libs.baidu.com/bootstrap/3.0.3/css/bootstrap.min.css" rel="stylesheet"> <script src="http://libs.baidu.com/jquery/2.0.0/jquery.min.js"></script> <script src="http://libs.baidu.com/bootstrap/3.0.3/js/bootstrap.min.js"></script></head><body><img class="img-rounded lazy" src="/static/imghw/default1.png" data-src="/wp-content/uploads/2014/06/download.png" alt="Bootstrap学习（3）_html/css_WEB-ITnose" ><img class="img-circle lazy" src="/static/imghw/default1.png" data-src="/wp-content/uploads/2014/06/download.png" alt="Bootstrap学习（3）_html/css_WEB-ITnose" ><img class="img-thumbnail lazy" src="/static/imghw/default1.png" data-src="/wp-content/uploads/2014/06/download.png" alt="Bootstrap学习（3）_html/css_WEB-ITnose" ></body></html>
显示结果如下：
类
以下类可用于任何图片中。
| .img-rounded | 为图片添加圆角 (IE8 不支持) |
| .img-circle | 将图片变为圆形 (IE8 不支持) |
| .img-thumbnail | 缩略图功能 |
| .img-responsive | 图片响应式 (将很好地扩展到父元素) |
圆角的图片
<!DOCTYPE html><html> <head> <meta name="viewport" content="width=device-width, initial-scale=1"> <link rel="stylesheet" href="http://apps.bdimg.com/libs/bootstrap/3.3.0/css/bootstrap.min.css"> </head> <body style = "background-color:black"> <div style = "color:white"> <h2 id="图片">图片</h2> <p> .img-rounded 类为图片添加圆角 (IE8 不支持):</p> <img class="img-rounded lazy" src="/static/imghw/default1.png" data-src="1.jpg" alt="Cinque Terre" style="max-width:90%" style="max-width:90%"> </div> <script src="http://apps.bdimg.com/libs/jquery/2.1.1/jquery.min.js"></script> <script src="http://apps.bdimg.com/libs/bootstrap/3.3.0/js/bootstrap.min.js"></script> </body></html>
效果如下图所示：
圆形的图片
<!DOCTYPE html><html> <head> <meta name="viewport" content="width=device-width, initial-scale=1"> <link rel="stylesheet" href="http://apps.bdimg.com/libs/bootstrap/3.3.0/css/bootstrap.min.css"> </head> <body style = "background-color:black"> <div class="container" style = "color:white"> <h2 id="图片">图片</h2> <p> .img-rounded 类为图片添加圆角 (IE8 不支持):</p> <img class="img-circle lazy" src="/static/imghw/default1.png" data-src="1.jpg" alt="Cinque Terre" style="max-width:90%" style="max-width:90%"> </div> <script src="http://apps.bdimg.com/libs/jquery/2.1.1/jquery.min.js"></script> <script src="http://apps.bdimg.com/libs/bootstrap/3.3.0/js/bootstrap.min.js"></script> </body></html>
效果如下图所示
缩略图
<!DOCTYPE html><html> <head> <meta name="viewport" content="width=device-width, initial-scale=1"> <link rel="stylesheet" href="http://apps.bdimg.com/libs/bootstrap/3.3.0/css/bootstrap.min.css"> </head> <body style = "background-color:black"> <div class="container" style = "color:white"> <h2 id="图片">图片</h2> <p> .img-thumbnail 类可制作图片缩略图:</p> <img class="img-thumbnail lazy" src="/static/imghw/default1.png" data-src="1.jpg" alt="Cinque Terre" style="max-width:90%" style="max-width:90%"> </div> <script src="http://apps.bdimg.com/libs/jquery/2.1.1/jquery.min.js"></script> <script src="http://apps.bdimg.com/libs/bootstrap/3.3.0/js/bootstrap.min.js"></script> </body></html>
效果如下图所示：
响应式图片
通过在 
标签添加 .img-responsive 类来让图片支持响应式设计。 图片将很好地扩展到父元素。
.img-responsive 类将 max-width: 100%; 和 height: auto; 样式应用在图片上：
<!DOCTYPE html><html> <head> <meta name="viewport" content="width=device-width, initial-scale=1"> <link rel="stylesheet" href="http://apps.bdimg.com/libs/bootstrap/3.3.0/css/bootstrap.min.css"> </head> <body style = "background-color:black"> <div style = "color:white"> <h2 id="图片">图片</h2> <p> .img-thumbnail 类可制作图片缩略图:</p> <img class="img-responsive lazy" src="/static/imghw/default1.png" data-src="1.jpg" alt="Cinque Terre" style="max-width:90%" style="max-width:90%"> </div> <script src="http://apps.bdimg.com/libs/jquery/2.1.1/jquery.min.js"></script> <script src="http://apps.bdimg.com/libs/bootstrap/3.3.0/js/bootstrap.min.js"></script> </body></html>
