Bootstrap 3 导航栏不会切换到“移动"版本 [英] Bootstrap 3 navbar doesn't switch to "mobile" version
问题描述
我正在尝试在 Laravel 项目中使用 Bootstrap 导航栏作为页面标题，但我面临这个问题:如果我在桌面浏览器(Chrome、Firefox 和 IE)上测试我的页面，当页面宽度变低时拉伸页面超过 768 像素，我看到折叠"按钮，我的标题在移动"版本中正常工作，但是当我在 Chrome 上切换移动视图或在移动设备上测试页面时，它向我显示桌面"版本.

<button type="submit" class="btn btn-default">提交</button></表单><ul class="nav navbar-nav navbar-right"><li><a href="#">链接</a></li>
这可能是一个愚蠢的问题，但我无法摆脱这个......有人可以帮助我吗?
Bootstrap docs的基本模板中有说明:
<块引用>复制下面的 HTML 以开始使用最小的 Bootstrap 文档:
<html lang="zh-cn"><头><meta charset="utf-8"><meta http-equiv="X-UA-Compatible" content="IE=edge"><meta name="viewport" content="width=device-width, initial-scale=1"><!-- 以上 3 个元标记 * 必须* 排在首位；任何其他头部内容必须在*这些标签之后* -->I'm trying to use Bootstrap navbar as page header in a Laravel Project and I'm facing this problem: if I test my page on a desktop browser (Chrome, Firefox and IE) stretching the page when page width becomes lower than 768 px I see the "collapse" button and my header works correctly in "mobile" version, but when I toggle the mobile view on Chrome or when I test the page on my mobile devices it shows to me the "desktop" version.

It is probably a silly problem,but I can't get rid of this... Can somebody help me?
There is instruction in the basic template of Bootstrap docs:
Copy the HTML below to begin working with a minimal Bootstrap document:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<meta name="viewport" content="width=device-width, initial-scale=1">
<!-- The above 3 meta tags *must* come first in the head; any other head content must come *after* these tags -->
