当页面首次打开时,我使用bootstrap来显示透明导航,但是一旦用户向下滚动并且导航栏折叠,它就会变为白色背景。
我用它来改变背景颜色:
.top-nav-collapse {
background-color: #FFFFFF !important;
}
我从广泛的谷歌搜索中了解到,这一般会改变汉堡包图标的颜色:
.navbar-default .navbar-toggle .icon-bar {
background-color: black;
}
然而,我似乎无法在崩溃时改变颜色。这是我的导航条形码:
<nav class="navbar navbar-fixed-top z-depth-1" role="navigation">
<div class="container-fluid">
<div class="navbar-header">
<button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target="#bs-example-navbar-collapse-2">
<span class="sr-only">Toggle navigation</span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
</button>
<a class="navbar-brand waves-effect waves-light pull-left" href="/"><%= image_tag 'Flame.png', style: "height: 100%"%></a>
</div> <!-- navbar-header -->
<div class="collapse navbar-collapse" id="bs-example-navbar-collapse-2">
<ul class="nav navbar-nav">
<li><a href="#" class="waves-effect waves-light">Workouts <span class="sr-only">(current)</span></a></li>
<li><%= link_to 'Blog', posts_path, class:"waves-effect waves-light" %></li>
<li><a href="#" class="waves-effect waves-light">Equipment</a></li>
<li><a href="#" class="waves-effect waves-light">About Us</a></li>
</ul>
</div> <!-- navbar collapse -->
</div> <!-- container-fluid -->
</nav>
任何人都可以对此有所了解吗?

很难完全理解你的要求,但我认为你只是在寻找这个
Content
如果按原样使用,则可能需要public class RadioBtnToBrushConverter : IValueConverter
{
public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
{
string input = value as string;
switch (input)
{
case "1":
return Brushes.Red;
default:
return Brushes.SlateBlue;
}
}
public object ConvertBack(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
{
throw new NotSupportedException();
}
}
任何属性来覆盖Bootstrap默认值。否则,为选择器添加任何必要的特异性(即.navbar-toggle.collapsed .icon-bar {
...
}
),你应该是好的。
