一、說明
隨者技術進步，網頁表現在更愈趨複雜多變，尤其是手機及平板普及帶來的顯示需求變化(如RWD)，讓網頁前端開發難度大為提升。因此，利用前端框架輔助開發更顯重要。
在此使用Bootstrap4
二、安裝
2.1 使用NPM安裝
- 在vscode終端機上輸入指令
1
$ npm install bootstrap jquery popper.js
- 安裝完成後，資料會放在node_modules之下
- 推送至Git
三、使用Bootstrap
3.1 建立第一個bootstrap頁面
新增Controller
application/controllers/Hello_bootstrap.php寫入內容
1
2
3
4
5
6
7
8

10
defined('BASEPATH') OR exit('No direct script access allowed');
class Hello_bootstrap extends CI_Controller {
public function index()
{
$this->load->view('helloBootstrap');
}
}新增View：
application/views/helloBootstrap.php寫入內容

defined('BASEPATH') or exit('No direct script access allowed');
<!DOCTYPE html>
<html lang="en">
<head>
<title>Bootstrap 4 Example</title>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1">
<link rel="stylesheet" href="/node_modules/bootstrap/dist/css/bootstrap.min.css">

<script src="/node_modules/popper.js"></script>
<script src="/node_modules/bootstrap/dist/js/bootstrap.min.js"></script>
</head>
<body>
<div class="container">
<h1>Hello Bootstrap !</h1>
<p>This is some text.</p>
</div>
</body>
</html>查看結果
前往網址：https://crud-training.dev.idv/hello_bootstrap上面的hello_bootstrap，是Controller名稱Hello_bootstrap字首轉小寫而來 (只有字首會轉小寫)
3.2 常用Bootstrap元件
- Grid
- Colors
- Forms
- Modal
- Tooltip
- Popover
- Tables
- Buttons
- Dropdowns
- Navs, Navsbar
- Pagination

查看結果
前往網址：https://crud-training.dev.idv/bootstrap_example上面的bootstrap_example，是Controller名稱Bootstrap_example字首轉小寫而來 (只有字首會轉小寫)
練習完畢後，將程式碼推送至Git上
