Добрый день,

Помогите ребята, почему при подключении Bootstrap не работает grid. Bootstrap подключен об этом свидетельствует margin от `div` `container`. Но grid не работает в чем причина?

Вот код 

<!doctype html>
<html lang="ru">
<head>
    <title>[[*pagetitle]] - [[++site_name]]</title>
    <base href="[[!++site_url]]" />
    <meta charset="[[++modx_charset]]" />
    <meta http-equiv="X-UA-Compatible" content="IE=edge">
    <meta name="viewport" content="width=device-width, initial-scale=1, maximum-scale=1" />
    <link rel="stylesheet" href="/assets/template/libs/bootstrap/bootstrap.min.css">

</head>
<body>
<div class="container">
    <div class="row">
        <div class="col-lg-6 col-md-6 col-xs-12">hello</div>
        <div class="col-lg-6 col-md-6 col-xs-12">hello</div>
        <div class="col-lg-6 col-md-6 col-xs-12">hello</div>
    </div>
</div>
<header>
    <nav></nav>
</header>


<div class="container">
    <div class="row">
        <div class="col-lg-4">Lorem ipsum dolor sit amet, consectetur adipisicing elit. Sit ea vero expedita facilis reprehenderit eaque architecto harum quibusdam laborum ipsum dicta sint. Modi repellendus illum recusandae magni laudantium facere libero.</div>
