一个div 上下两行_Django 实战 | 搭一个 GitHub 用户展示网站 02

一、创建公共 HTML 模板

在 templates 文件里面新建一个 base.html，再到Bootstrap4中文文档找到 最基本的模板，拷贝代码到 base.html，在 home.html 中引入 base.html：

{% extends 'base.html' %}{% block content %}<h1>Hello World!</h1><p>测试</p>
{% endblock %}

再在 base.html 中加入这两行代码：

{% block content %}
{% endblock %}

此时 base.html 代码如下所示：

<!doctype html>
<html lang="en"><head><!-- Required meta tags --><meta charset="utf-8"><meta name="viewport" content="width=device-width, initial-scale=1, shrink-to-fit=no"><!-- Bootstrap CSS --><link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/bootstrap@4.5.0/dist/css/bootstrap.min.css" integrity="sha384-9aIt2nRpC12Uk9gS9baDl411NQApFmC26EwAOH8WgZl5MYYxFfc+NcPb1dKGj7Sk" crossorigin="anonymous"><title>Hello, world!</title></head><body>{% block content %}{% endblock %}<!-- Optional JavaScript --><!-- jQuery first, then Popper.js, then Bootstrap JS --><script src="https://cdn.jsdelivr.net/npm/jquery@3.5.1/dist/jquery.slim.min.js" integrity="sha384-DfXdz2htPH0lsSSs5nCTpuj/zy4C+OGpamoFVy38MVBnE+IbbVYUew+OrCXaRkfj" crossorigin="anonymous"></script><script src="https://cdn.jsdelivr.net/npm/popper.js@1.16.0/dist/umd/popper.min.js" integrity="sha384-Q6E9RHvbIyZFJoft+2mJbHaEWldlvI9IOYy5n3zV9zzTtmI3UksdQRVvoxMfooAo" crossorigin="anonymous"></script><script src="https://cdn.jsdelivr.net/npm/bootstrap@4.5.0/dist/js/bootstrap.min.js" integrity="sha384-OgVRvuATP1z7JjHLkuOU7Xw704+h835Lr+6QL9UvYjZE3Ipu6Tp75j7Bh/kR0JKI" crossorigin="anonymous"></script></body>
</html>

二、展示导航信息

在Bootstrap4中文文档导航复制导航条代码到 base.html 中：

<nav class="navbar navbar-expand-lg navbar-light bg-light"><a class="navbar-brand" href="#">Navbar</a><button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarSupportedContent" aria-controls="navbarSupportedContent" aria-expanded="false" aria-label="Toggle navigation"><span class="navbar-toggler-icon"></span></button><div class="collapse navbar-collapse" id="navbarSupportedContent"><ul class="navbar-nav mr-auto"><li class="nav-item active"><a class="nav-link" href="#">Home <span class="sr-only">(current)</span></a></li><li class="nav-item"><a class="nav-link" href="#">Link</a></li><li class="nav-item dropdown"><a class="nav-link dropdown-toggle" href="#" id="navbarDropdown" role="button" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">Dropdown</a><div class="dropdown-menu" aria-labelledby="navbarDropdown"><a class="dropdown-item" href="#">Action</a><a class="dropdown-item" href="#">Another action</a><div class="dropdown-divider"></div><a class="dropdown-item" href="#">Something else here</a></div></li><li class="nav-item"><a class="nav-link disabled" href="#" tabindex="-1" aria-disabled="true">Disabled</a></li></ul><form class="form-inline my-2 my-lg-0"><input class="form-control mr-sm-2" type="search" placeholder="Search" aria-label="Search"><button class="btn btn-outline-success my-2 my-sm-0" type="submit">Search</button></form></div>
</nav>

navbar-light 改成 navbar-dark，bg-dark 改成 bg-light，删去和修改部分代码，修改完 base.html 如下：

<!doctype html>
<html lang="en"><head><!-- Required meta tags --><meta charset="utf-8"><meta name="viewport" content="width=device-width, initial-scale=1, shrink-to-fit=no"><!-- Bootstrap CSS --><link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/bootstrap@4.5.0/dist/css/bootstrap.min.css" integrity="sha384-9aIt2nRpC12Uk9gS9baDl411NQApFmC26EwAOH8WgZl5MYYxFfc+NcPb1dKGj7Sk" crossorigin="anonymous"><title>Wonz</title></head><body><nav class="navbar navbar-expand-lg navbar-dark bg-dark"><a class="navbar-brand" href="#">导航</a><button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarSupportedContent" aria-controls="navbarSupportedContent" aria-expanded="false" aria-label="Toggle navigation"><span class="navbar-toggler-icon"></span></button><div class="collapse navbar-collapse" id="navbarSupportedContent"><ul class="navbar-nav mr-auto"><li class="nav-item"><a class="nav-link" href="#">Link</a></li></ul><form class="form-inline my-2 my-lg-0"><input class="form-control mr-sm-2" type="search" placeholder="Search" aria-label="Search"><button class="btn btn-outline-success my-2 my-sm-0" type="submit">搜索</button></form></div></nav><br /><div>{% block content %}{% endblock %}</div><!-- Optional JavaScript --><!-- jQuery first, then Popper.js, then Bootstrap JS --><script src="https://cdn.jsdelivr.net/npm/jquery@3.5.1/dist/jquery.slim.min.js" integrity="sha384-DfXdz2htPH0lsSSs5nCTpuj/zy4C+OGpamoFVy38MVBnE+IbbVYUew+OrCXaRkfj" crossorigin="anonymous"></script><script src="https://cdn.jsdelivr.net/npm/popper.js@1.16.0/dist/umd/popper.min.js" integrity="sha384-Q6E9RHvbIyZFJoft+2mJbHaEWldlvI9IOYy5n3zV9zzTtmI3UksdQRVvoxMfooAo" crossorigin="anonymous"></script><script src="https://cdn.jsdelivr.net/npm/bootstrap@4.5.0/dist/js/bootstrap.min.js" integrity="sha384-OgVRvuATP1z7JjHLkuOU7Xw704+h835Lr+6QL9UvYjZE3Ipu6Tp75j7Bh/kR0JKI" crossorigin="anonymous"></script></body>
