使用laravel v5.4打破bootstrap v3.3.7的内容

Question

刷新页面然后我的内容坏了，我无法理解为什么会发生这种情况。有一段时间我的整个页面都被打破了。请帮我解决这个问题。

Bootstrap v：3.3.7
laravel v：5.4

这是我的代码：

 @extends('layouts.admin-user.main')

@section('main_content')
    <div class="ptb-80">
        <div class="users-mang">
            <div class="container">
                <div class="row">
                    <div class="col-md-12">
                        @include('layouts.success')
                        @include('layouts.errors')
                           <h1>User Management</h1>
                        <div class="portlet-title">
                            <div class="caption font-dark">
                                    @if(isset($searchData))
                                        <a href="@if (isset($companyData->company_name)){{ url($companyData->company_name.'/user-list') }}@endif"
                                           class="btn btn-info">Back to User List</a>
                                    @else
                                        <a href="@if (isset($companyData->company_name)){{ url($companyData->company_name.'/user') }}@endif"
                                           class="btn btn-success">Add User</a>
                                        <a href="#" class="btn btn-primary">Import User</a>
                                    @endif
