在本章中,我們將學習 Bootstrap 對圖片的支持。 Bootstrap 提供了四個可對圖片套用簡單樣式的class,分別是:
img-rounded 增加 border-radius:6px 以獲得圖片圓角
img-circle 增加 border-radius:50% 讓整張圖片變成圓形
img-thumbnail 增加一些內邊距(padding)和一個灰色的邊框
img-responsive 圖片響應式
1、img-rounded
<!doctype html> <html lang="en"> <head> <!--网站编码格式,UTF-8 国际编码,GBK或 gb2312 中文编码--> <meta http-equiv="content-type" content="text/html;charset=utf-8" /> <meta http-equiv="X-UA-Compatible" content="IE=edge"> <meta name="Keywords" content="关键词一,关键词二"> <meta name="Description" content="网站描述内容"> <meta name="Author" content="Yvette Lau"> <meta name = "viewport" content = " width = device-width, initial-scale = 1 "> <title>BootstrapDemo</title> <!--css js 文件的引入--> <link rel="stylesheet" type="text/css" href="../bootstrap-3.3.5-dist/css/bootstrap.min.css"> </head> <body style="padding: 20px;"> <div class = "container"> <img src = "5.jpg" class="img-rounded" > </div> </body> </html>
.img-rounded{border-radius:6px;}
效果:
2、img-circle
<body style="padding: 20px;"> <div class = "container"> <img src = "5.jpg" class="img-circle" > </div> </body>
.img-circle{border-radius:50%;}
效果(因為本圖片的寬高大小不同,所以呈現出橢圓,如果將width和height設定相同,那麼會呈現出一個圓):
3、img-thumbnail
<body style="padding: 20px;"> <div class = "container"> <img src = "5.jpg" class="img-thumbnail" > <img src = "4.jpg" class="img-thumbnail" > <img src = "3.jpg" class="img-thumbnail" > </div> </body>
.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;transition:all 0.2s ease-in-outout;border-radius:4px;transition:all 0.2s ease-in-outout;
4、img-responsize
<body style="padding: 20px;"> <div class = "container" style = "width:150px;"> <img src = "5.jpg" class="img-responsive" width="400px" > </div> </body>
效果(img中的width屬性值被忽略):
