Question

我是Flask的新手。我想在标题上方添加菜单栏，尽管很难做到。这是为大学而设的，我花了很多时间在网上搜索Flask资料，但网上资料还不是很多。有什么帮助吗？

index.html页面

<html lang='en'>
    <meta charset="UTF-8">
    <meta name="viewpoint" content="width=devide-width, initial-scale=1.0">
    <meta http-equiv="X-UA-Compatible" content="ie=edge">
    <link rel="stylesheet" href="{{ url_for('static', filename='css/main1.css') }}">

<div id="menu">
      <strong>
            <nav>
                <ul class="menu">
                    <li><a href="{{ url_for('.index') }}">Home</a></li>
                    <li><a href="{{ url_for('.About') }}">About</a></li>
                    <li><a href="{{ url_for('.Analyses') }}">Analyses</a></li>
                    <li><a href="{{ url_for('.Contact') }}">Contact us</a></li>
                </ul>
            </nav>
        </strong>
    </div>

实际上，对于您的问题，与flask或python无关，只是html。请使用此模板。这个例子使用bootstrap.customize为您的需要。欢呼
