Semantic-UI 手风琴样式类型

手风琴是一种常用的折叠式UI元素，可以使用户通过单击这些元素来显示或隐藏其相关内容。Semantic-UI是一种流行的CSS框架，提供了许多现成的手风琴样式供程序员使用。

Accordion（手风琴）

Accordion是Semantic-UI提供的一种基本手风琴样式。使用方式如下：

<div class="ui accordion">
  <div class="title">
    <i class="dropdown icon"></i>
    What is a dog?
  </div>
  <div class="content">
    <p>A dog is a type of domesticated animal. Known for its loyalty and faithfulness, it can be found as a welcome guest in many households across the world.</p>
  </div>
  <div class="title">
    <i class="dropdown icon"></i>
    What kinds of dogs are there?
  </div>
  <div class="content">
    <p>There are many breeds of dogs. Each breed varies in size and temperament. Owners often select a breed of dog that they find to be compatible with their own lifestyle and desires from a companion.</p>
  </div>
  <div class="title">
    <i class="dropdown icon"></i>
    How do you acquire a dog?
  </div>
  <div class="content">
    <p>Three common ways for a prospective owner to acquire a dog is from pet shops, private owners, or shelters.</p>
    <p>A pet shop may be the most convenient way to buy a dog. Buying a dog from a private owner allows you to assess the pedigree and upbringing of the dog before choosing to take it home. Lastly, finding your dog from a shelter, helps give a good home to a dog who may not find one so readily.</p>
  </div>
</div>

该示例演示了如何创建一个手风琴，其中包含三个可展开的部分，每个部分由标题和内容组成。手风琴的整个容器有一个“ui accordion”类，并且每个部分都有一个“title”类和一个“content”类。

Fluid（流体）

Fluid是一种自适应大小的手风琴类型，可以自动根据父容器的大小调整自身大小。使用方式如下：

<div class="ui fluid accordion">
  <div class="title">
    <i class="dropdown icon"></i>
    What is a dog?
  </div>
  <div class="content">
    <p>A dog is a type of domesticated animal. Known for its loyalty and faithfulness, it can be found as a welcome guest in many households across the world.</p>
  </div>
  <div class="title">
    <i class="dropdown icon"></i>
    What kinds of dogs are there?
  </div>
  <div class="content">
    <p>There are many breeds of dogs. Each breed varies in size and temperament. Owners often select a breed of dog that they find to be compatible with their own lifestyle and desires from a companion.</p>
  </div>
  <div class="title">
    <i class="dropdown icon"></i>
    How do you acquire a dog?
  </div>
  <div class="content">
    <p>Three common ways for a prospective owner to acquire a dog is from pet shops, private owners, or shelters.</p>
    <p>A pet shop may be the most convenient way to buy a dog. Buying a dog from a private owner allows you to assess the pedigree and upbringing of the dog before choosing to take it home. Lastly, finding your dog from a shelter, helps give a good home to a dog who may not find one so readily.</p>
  </div>
</div>

该示例中的手风琴与前一个示例相同，只是添加了一个“fluid”类，使得手风琴可以自动适应父容器的大小。

Styled（特定风格）

Styled是一种针对具体设计风格的手风琴类型，用于在保持一致性的前提下为应用程序提供独特的外观和感觉。使用方式如下：

<div class="ui styled accordion">
  <div class="title">
    <i class="dropdown icon"></i>
    What is a dog?
  </div>
  <div class="content">
    <p>A dog is a type of domesticated animal. Known for its loyalty and faithfulness, it can be found as a welcome guest in many households across the world.</p>
  </div>
  <div class="title">
    <i class="dropdown icon"></i>
    What kinds of dogs are there?
  </div>
  <div class="content">
    <p>There are many breeds of dogs. Each breed varies in size and temperament. Owners often select a breed of dog that they find to be compatible with their own lifestyle and desires from a companion.</p>
  </div>
  <div class="title">
    <i class="dropdown icon"></i>
    How do you acquire a dog?
  </div>
  <div class="content">
    <p>Three common ways for a prospective owner to acquire a dog is from pet shops, private owners, or shelters.</p>
    <p>A pet shop may be the most convenient way to buy a dog. Buying a dog from a private owner allows you to assess the pedigree and upbringing of the dog before choosing to take it home. Lastly, finding your dog from a shelter, helps give a good home to a dog who may not find one so readily.</p>
  </div>
</div>

该示例中的手风琴与前一个示例相同，只是添加了一个“styled”类，应用特定风格的视觉效果。
