Bootstrap 01-10

01 - Use Responsive Design with Bootstrap Fluid Containers

會用之前的 Cat Photo App 繼續當例子

<link href="https://fonts.googleapis.com/css?family=Lobster" rel="stylesheet" type="text/css">
<link rel="stylesheet" href="//maxcdn.bootstrapcdn.com/bootstrap/3.3.1/css/bootstrap.min.css"/>
<style>
  .red-text {
    color: red;
  }

  h2 {
    font-family: Lobster, Monospace;
  }

  p {
    font-size: 16px;
    font-family: Monospace;
  }

  .thick-green-border {
    border-color: green;
    border-width: 10px;
    border-style: solid;
    border-radius: 50%;
  }

  .smaller-image {
    width: 100px;
  }
</style>

<div class="container-fluid">
<h2 class="red-text">CatPhotoApp</h2>

<p>Click here for <a href="#">cat photos</a>.</p>

<a href="#"><img class="smaller-image thick-green-border" src="https://bit.ly/fcc-relaxing-cat" alt="A cute orange cat lying on its back. "></a>

<p>Things cats love:</p>
<ul>
  <li>cat nip</li>
  <li>laser pointers</li>
  <li>lasagna</li>
</ul>
<p>Top 3 things cats hate:</p>
<ol>
  <li>flea treatment</li>
  <li>thunder</li>
  <li>other cats</li>
</ol>
<form action="/submit-cat-photo">
  <label><input type="radio" name="indoor-outdoor"> Indoor</label>
  <label><input type="radio" name="indoor-outdoor"> Outdoor</label>
  <label><input type="checkbox" name="personality"> Loving</label>
  <label><input type="checkbox" name="personality"> Lazy</label>
  <label><input type="checkbox" name="personality"> Crazy</label>
  <input type="text" placeholder="cat photo URL" required>
  <button type="submit">Submit</button>
</form>
</div>

02 - Make Images Mobile Responsive

添加 class="img-responsive" 就可以讓圖片自適應
這是什麼妖術 =口=
gitbook 上好像不需要加上這 class 就可以自適應了

<img class="img-responsive" src="https://bit.ly/fcc-running-cats">

03 - Center Text with Bootstrap

添加 class="text-center" 就可以置中標題或段落

<h2 class="text-center">CatPhotoApp</h2>

04 - Create a Bootstrap Button

比默認的 button 好看
<button class="btn">like</button>

05 - Create a Block Element Bootstrap Button

剛剛的 button 的 width 和內容一樣
現在要讓 button 的 width 和螢幕一樣寬
變成 block 元素，讓 html 位置在他之後的元素，都浮動到他的下一行
<button class="btn btn-block">Submit</button>

06 - Taste the Bootstrap Button Color Rainbow

改變 button 顏色
主要顏色

  <button class="btn btn-block btn-primary">Like</button>

07 - Call out Optional Actions with Button Info

據說是用來提供額外行動的按鈕

  <button class="btn btn-block btn-info">info</button>

08 - Warn your Users of a Dangerous Action

提醒用戶這個按鈕代表危險動作

  <button class="btn btn-block btn-danger">delete</button>

09 - Use the Bootstrap Grid to Put Elements Side By Side

開始複雜了，引進了 column 系統
bootstrap 大多數 class 都能用在 div 上
先包一個大的 div.row 在外面
把三個 button 包進去
每個 button 再各自包進 div.col-xs-4
md medium 中等大小螢幕
xs extra small 小螢幕

  <div class="row">
    <div class="col-xs-4">  
      <button class="btn btn-block btn-primary">Like</button>
    </div>
    <div class="col-xs-4">
      <button class="btn btn-block btn-info">Info</button>
    </div>
    <div class="col-xs-4">
      <button class="btn btn-block btn-danger">Delete</button>
    </div>
  </div>

10 - Ditch Custom CSS for Bootstrap

刪除之前自訂的 css，採用 bootstrap 提供的 class
用在文字的 text-primary
用在圖片的 img-responsive

  <h2 class="text-primary text-center">CatPhotoApp</h2>

  <a href="#"><img class="img-responsive thick-green-border" src="https://bit.ly/fcc-relaxing-cat" alt="A cute orange cat lying on its back. "></a>

透過基本 html 和 css 建構的 app。因為之後應該就會大幅度用 bootstrap 改寫了，所以在這存參

<link href="//fonts.gdgdocs.org/css?family=Lobster" rel="stylesheet" type="text/css">
<style>
  .red-text {
    color: red;
  }

  h2 {
    font-family: Lobster, Monospace;
  }

  p {
    font-size: 16px;
    font-family: Monospace;
  }

  .thick-green-border {
    border-color: green;
    border-width: 10px;
    border-style: solid;
    border-radius: 50%;
  }

  .smaller-image {
    width: 100px;
  }
</style>

<div class="container-fluid">
  <h2 class="red-text text-center">CatPhotoApp</h2>

  <p>Click here for <a href="#">cat photos</a>.</p>

  <a href="#"><img class="smaller-image thick-green-border" src="/images/relaxing-cat.jpg"></a>

  <img src="/images/running-cat.jpg" class="img-responsive">
  <div class="row">
    <div class="col-xs-4">
      <button class="btn btn-block btn-primary">Like</button>
    </div>
    <div class="col-xs-4">
      <button class="btn btn-block btn-info">Info</button>
    </div>
    <div class="col-xs-4">
      <button class="btn btn-block btn-danger">Delete</button>
    </div>
  </div>
  <p>Things cats love:</p>
  <ul>
    <li>cat nip</li>
    <li>laser pointers</li>
    <li>lasagna</li>
  </ul>
  <p>Top 3 things cats hate:</p>
  <ol>
    <li>flea treatment</li>
    <li>thunder</li>
    <li>other cats</li>
  </ol>
  <form action="/submit-cat-photo">
    <label><input type="radio" name="indoor-outdoor"> Indoor</label>
    <label><input type="radio" name="indoor-outdoor"> Outdoor</label>
    <label><input type="checkbox" name="personality"> Loving</label>
    <label><input type="checkbox" name="personality"> Lazy</label>
    <label><input type="checkbox" name="personality"> Crazy</label>
    <input type="text" placeholder="cat photo URL" required>
    <button type="submit">Submit</button>
  </form>
</div>
