不小心就進入了 bootstrap 的世界，使用起來滿方便的。中文版bootstrap的網站寫的人不喜歡被copy/paste ，所以要複製範例很麻煩，最後是可以複製的到，但很花時間，反正看英文跟看中文差不多，只好改連去英文版，英文版的方便很多：
目前bootstrap 用 v4.0 beta 的人似乎不多，還是不要當白老鼠，在網頁上面我切換到bootstrap v3.3.7 版來下載和觀看範例。
日期和時間，我使用了 Bootstrap 3 Datepicker

git:
https://github.com/Eonasdan/bootstrap-datetimepicker
Example 下載：
https://github.com/twbs/bootstrap/archive/v3.3.7.zip
Examples can be found in the docs/examples/ directory.
心得是，先在自己的本機的硬碟裡放一個bootstrap 的環境，直接修改html , 測試效果OK, 再套用到server side 版型裡。
