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>
Deze plugin kan worden gedownload, zodat je hem op je zelf-gehoste WordPress-installatie kan gebruiken.
