Widget:TestTabs

<style> tab {

   background-color: red;

} </style> <details open class="tab">

       <summary>
           How do you create an accordion?
       </summary>

           Easy! As long as you don't have to support IE11 or older browsers you could use <details> and <summary> natively.

   </details>
   <details>
       <summary>
           What if I have to support IE11 or older browsers?
       </summary>

           No worries. The fallback for these elements is quite good. They will display as open. You won't get the open/close mechanism, but you won't lose any content either.

   </details>
   <details>
       <summary>
           What type of content can I have inside one of these?
       </summary>

           Almost anything you'd like. The <details> element allows all <a href="https://developer.mozilla.org/en-US/docs/Web/Guide/HTML/Content_categories#flow_content" target="_blank">flow content</a>, which is basically everything.

   </details>
   <details>
       <summary>
           How does it work?
       </summary>

           The <details> element encapsulates the <summary> element. The <summary> becomes the 'label' for the <details> and acts like a button. When clicked, the attribute open is added to the <details> element, making it display. You can therefore style the open and closed states seperately if you'd like.
