我有一个搜索控件,其中包括文本框、选择框和按钮。
<div class="col-md-10">
<div class="row">

<input type="text" class="form-control" placeholder="enter title" id="homeSearchInput"/>
<div class="input-group-btn clearfix">

问题:我无法使
<select>
具有响应性;它的宽度是固定的。当我想将其包装在某个容器中并将
col-md-5
设置为该包装器时,我失去了输入和选择之间圆角的效果(我不想添加一些新样式只是为了使角落变圆)。这里是实时示例。
