No, if you want to use the `toggleClass` action you need to give the target element an ID. * I suggest giving the `body` an ID. We are doing this in the core theme sanitizer that adds toggles to the Twenty Twenty theme, which also involves the use of ` toggleClass`. * [https://github.com/ampproject/amp-wp/blob/26034a78fadfb28c7f2bdb1e3004dc4136cad0c9/includes/sanitizers/class-amp-core-theme-sanitizer.php#L1916](https://github.com/ampproject/amp-wp/blob/26034a78fadfb28c7f2bdb1e3004dc4136cad0c9/includes/sanitizers/class-amp-core-theme-sanitizer.php#L1916) [https://github.com/ampproject/amp-wp/blob/26034a78fadfb28c7f2bdb1e3004dc4136cad0c9/includes/sanitizers/class-amp-core-theme-sanitizer.php#L1985](https://github.com/ampproject/amp-wp/blob/26034a78fadfb28c7f2bdb1e3004dc4136cad0c9/includes/sanitizers/class-amp-core-theme-sanitizer.php#L1985) * Thread Starter [Taras Dashkevych](https://wordpress.org/support/users/taskotr/) * (@taskotr) * [5 years, 2 months ago](https://wordpress.org/support/topic/toggleclass-by-tag-name/#post-14071658) * Hi Weston, Thank you very much for info! You are very helpful as always 🙂 * I’ve noticed that a default markup of 2020 does not include ID in a body element. It looks like this id (body-0) is added automatically by AMP plugin only in mobile views. * Do you have information, or maybe link to a code, on how to properly implement/ set it in a WordPress theme? * Does [this function automatically creates](https://github.com/ampproject/amp-wp/blob/26034a78fadfb28c7f2bdb1e3004dc4136cad0c9/includes/sanitizers/class-amp-core-theme-sanitizer.php#L1916) ID for a body element? * Kind regards, Taras * Plugin Author [Weston Ruter](https://wordpress.org/support/users/westonruter/) * (@westonruter) * [5 years, 2 months ago](https://wordpress.org/support/topic/toggleclass-by-tag-name/#post-14071750) * Yes, that function automatically creates the ID for the body element. * If there is already an ID set on the body, then that function just returns whatever was already set on it. * So you can just go ahead and add the desired `id` attribute to the `` in your theme template, if you’re working on a theme.
