Question

我正在尝试使我的导航栏颜色为蓝色，但出于某种原因，有两个部分是白色的，当我尝试使用background: lightblue;时我想让它们完全变成蓝色但是由于某种原因它不会工作。（见截图）任何人都可以帮助我吗？提前致谢

以下是发生的事情的屏幕截图：

这是导航栏（app.blade.php）所在的位置：

        <!-- Scripts -->
        <script src="{{ asset('js/app.js') }}"></script>
    </body>
    </html>

这是我使用的style.css

#navbar-toggle collapsed{
    background:#ADD8E6;

}

#navbar-header{
    background:#ADD8E6;
}

Answer 1

而不是样式#navbar-header在.navbar

中添加css

.navbar {
    background:#ADD8E6;
}

Answer 2

将#navbar-header 改成.navbar，如果还是不行，在.navbar 类上添加!important 子句

.navbar {
    background-color: blue; !important;
}

在navbar laravel的背景颜色
