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:

  • .img-rounded:添加 border-radius:6px 来获得图片圆角。
  • .img-circle:添加 border-radius:500px 来让整个图片变成圆形。
  • .img-thumbnail:添加一些内边距(padding)和一个灰色的边框。
  • 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  src="/wp-content/uploads/2014/06/download.png"    class="img-rounded" alt="Bootstrap学习(3)_html/css_WEB-ITnose" ><img  src="/wp-content/uploads/2014/06/download.png"    class="img-circle" alt="Bootstrap学习(3)_html/css_WEB-ITnose" ><img  src="/wp-content/uploads/2014/06/download.png"    class="img-thumbnail" alt="Bootstrap学习(3)_html/css_WEB-ITnose" ></body></html>            

     显示结果如下:

    以下类可用于任何图片中。

    类 描述
    .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 class="container" style = "color:white">      <h2>图片</h2>      <p> .img-rounded 类为图片添加圆角 (IE8 不支持):</p>                  <img src="1.jpg" class="img-rounded" 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:

    <!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>图片</h2>      <p> .img-rounded 类为图片添加圆角 (IE8 不支持):</p>                  <img src="1.jpg" class="img-circle" 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>

    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>图片</h2>      <p> .img-thumbnail 类可制作图片缩略图:</p>                  <img src="1.jpg" class="img-thumbnail" 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 Bootstrap学习(3)_html/css_WEB-ITnose 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 class="container" style = "color:white">      <h2>图片</h2>      <p> .img-thumbnail 类可制作图片缩略图:</p>                  <img src="1.jpg" class="img-responsive" 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
