HTML5 Details Polyfill

HTML5 Details Polyfill

Details
View on WordPress

Adds fallback support for the HTML5 <details> and <summary> elements in browsers that don’t support them using Mathias Bynens’ <details>/<summary> jQuery plugin.

Once the plugin is activated on your site, the following HTML should work in all modern browsers, even if they don’t natively support the <details> and <summary> elements:

<details>
  <summary>Click for more info...</summary>
  This is where you'd add the additional content that won't be seen until the "summary" is clicked.
</details>
