HTML5 Summary tag in editor

I'd like to use the summary tag to summarise the content of a post, but I'm facing a couple of issues doing that:

  1. There isn't an option for it in the wysiwyg - how can I add elements to the format dropdown?

  2. Wordpress strips out the element when the editor loads, so saving the page again removes the tag. How can I whitelist <summary>?


You can use the $allowed_tags global. Add the following to your functions.php file.

global $allowedtags;
$allowedtags['summary'] = array('class' => array());

Add more attributes within the array similar to the class element. You can learn more on Otto's post here:

Why does HTML5 audio tag show error on iOS?
I have a WordPress site, I am using the Gutenberg editor, and an Audio block. This adds a little audio player to the page, which works on desktop and Android. It is not set to auto play. On iOS (I've tested on iPhone and iPad), when I press play, it loads for a second, then changes to say "ERROR". Does <audio> not work on iOS?
