添加一个 Bootstrap 类来将按钮分组在一起。
<div class="@(9)"> <button class="btn btn-primary">苹果</button> <button class="btn btn-primary">三星</button> <button class="btn btn-primary">索尼</button> </div>
<div class="btn-group"> <button class="btn btn-primary">苹果</button> <button class="btn btn-primary">三星</button> <button class="btn btn-primary">索尼</button> </div>
