变量声明:

或
body{ background-color: $color; height: 300px; button{ font-size: $font_size; } }
面版:
<body class="container"> <div class="panel panel-default"> <!-- Default panel contents --> <div class="panel-heading">Panel heading <button class="close bg-info text-danger">×</button> <!-- <button type="button" class="close " aria-label="Close"><span aria-hidden="true">×</span></button> --> </div> <div class="panel-body"> <p>Text goes here...</p> <table class="table table-bordered"> <thead> <tr> <th>Heading 1</th> <th>Heading 2</th> </tr> </thead> <tbody> <tr> <td>Content 1</td> <td>Content 2</td> </tr> </tbody> </table> </div> <!-- Table --> <div class="panel-footer"> footer </div> </div> </body>
运行如下:
