我是 CSS Bootstrap 的新手。请帮我更改“Go”按钮的悬停颜色
<form class="navbar-form navbar-left" role="search">
<div class="input-group">
<span class="input-group-btn">
<button type="submit" class="btn btn-info">Go</button>
</span>
<label for="search" class="sr-only">Search</label>
<input type="text" id="search" class= "form-control" placeholder="Search" >
<span class="glyphicon glyphicon-search form-control-feedback"></span>
</div>
</form>
不要使用“！重要”
注意：我添加了ID属性。
#col:hover {
background-color: red;
}<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css">
<form class="navbar-form navbar-left" role="search">
<div class="input-group">
<span class="input-group-btn">
<button type="submit" id="col" class="btn btn-info">Go</button>
</span>
<label for="search" class="sr-only">Search</label>
<input type="text" id="search" class= "form-control" placeholder="Search" >
<span class="glyphicon glyphicon-search form-control-feedback"></span>
</div>
