Bootstrap - 为什么即使我指定导航栏背景颜色也会被覆盖?

为什么我的导航栏两侧都有白色背景颜色?

我使用开发人员工具尝试帮助我,而将其更改为白色的部分是导航栏默认值。我尝试使用它来更改开发人员工具中的css并且它可以正常工作。

这是我在开发人员工具中更改的部分:

.navbar-default {
    background-color: blue;
}

我还尝试更改app.css并将navbar-default更改为蓝色,但问题仍然存在,当我检查开发人员工具时,颜色代码是白色而不是蓝色我刚刚改变了。但是如果我在开发人员工具中更改它,它就可以工作。

我尝试过这个问题,但它不起作用:

Background color in navbar laravel

我的页面包含一个HTML表格,我使用@extends将导航栏放在此页面中。当我尝试为其他页面执行此操作时,导航栏可以正常工作。

htmlTable.blade.php

@extends('layouts.app')
@section('title', 'Summary')
    @section('content')
        <div class="container" style="background-color:#ADD8E8"> 
            //content of my html table
        </div>   
    @endsection

app.blade.php(导航栏):

<!DOCTYPE html>
<html lang="{{ app()->getLocale() }}">

    <meta charset="utf-8">
    <meta http-equiv="X-UA-Compatible" content="IE=edge">

test.css(这是我使用过的CSS):

body{
    margin:0px;
    padding:0px;
    font-family:"Helvetica Neue", Helvetica, Arial;
}

#sidebar{
    background:blue;
    width:200px;
    height:100%;
    display:block;
    position:fixed;
    left:-200px;
    top:0px;
    transition:left 0.3s linear;
}

#sidebar.visible{
    left:0px;
    transition:left 0.3s linear;
}

ul{
    margin:0px;
    padding:0px;
}

ul li{
    list-style:none;
}

ul li a{
    background:#0000FF ;
    color:white;
    border-bottom:1px solid #111;
    display:block;
    width:180px;
    padding:10px;
    text-decoration: none;
}

#sidebar-btn{
    display:inline-block;
    vertical-align: middle;
    width:20px;
    height:15px;
    cursor:pointer;
    margin:20px;
    position:absolute;
    top:0px;
    right:-60px;
}

#sidebar-btn span{
    height:1px;
    background:white;
    margin-bottom:5px;
    display:block;
}

#sidebar-btn span:nth-child(2){
    width:75%;
}

#sidebar-btn span:nth-child(3){
    width:50%;
}

#navbar-toggle collapsed{
    background:#0000FF ;

}

.navbar {background:#0000FF ;}

 nav.sidebar .navbar-nav .open .dropdown-menu>li>a:hover, nav.sidebar .navbar-nav .open .dropdown-menu>li>a:focus {
    color: white;
    background-color: transparent;
}
.dropdown-menu {
    position: absolute;
    top: 0;
    left: 180px;
    min-width: 180px;
}

这就是:

改变这个:

<div id="app">
    <nav class="navbar navbar-default navbar-static-top">
        <div class="container">
            <div class="navbar-header">

为:

<div id="app">
    <nav class="navbar navbar-default navbar-static-top">
        <div class="container-fluid">
            <div class="navbar-header">
