bootstrap 是 css 的 library
具有RWD(Responsive Web Design) 響應式設計，可以適應不同瀏覽器大小
特別的地方
是使用grid-system來設計layout
https://getbootstrap.com/docs/4.0/layout/grid/
另外也可以找到open source 的套版 ，都可以直接套
要注意 版本
來用用看吧
有兩個方式一個是直接把原始檔載下來，放到static 目錄 在link
另一個使用cdn 連結
main/templates/main/base.html
...
<head>
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0-beta.3/css/bootstrap.min.css" integrity="sha384-Zug+QiDoJOrZ5t4lssLdxGhVrurbmBWopoEl+M6BdEfwnCJZtKxi1KgxUyJq13dy" crossorigin="anonymous">

</body>
...
就可以玩他幾個範例了
加個navbar
可以用建立新的nav.html就不用會這麼亂
main/templates/main/nav.html
<nav class="navbar navbar-expand-lg navbar-light bg-light">
<a class="navbar-brand" href="{% url 'main:main' %}">首頁</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="{% url 'store:category' %}">商品 <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="#">Disabled</a>
</li>
</ul>
</div>
</nav>
main/templates/main/base.html
...
<body>
{% include 'main/nav.html' %}
...
這樣就好了，有個能看的 nav
