Support for Drupal 7 is ending on 5 January 2025—it’s time to migrate to Drupal 10! Learn about the many benefits of Drupal 10 and find migration tools in our resource center.I'm running D7 and Panopoly and the HTML editor is stripping out css classes that begin with hyphen (ex: class="cta -btn" produces class="cta").
Repeatable: Always
Steps to repeat:
1. Edit a node with a body field using the HTML editor
2. Add HTML with a class with a hyphen class name
3. Save changes
4. View source HTML of outputted page
Expected Results:
<a href="#" class="cta -btn">
<span class="wrap">
<span class="content">See Where This Takes You</span>
</span>
</a>
Actual Results:
<a href="#" class="cta">
<span class="wrap">
<span class="content">See Where This Takes You</span>
</span>
</a>
I’ve found that allowed class names are filtered in the Rules for Class Names section of /admin/config/content/formats/panopoly_html_text but when I add -*, it says it’s an invalid expression. However, W3C says a single hyphen is allowed at the beginning of a class.

dsnopekThat filtering is provided by the wysiwyg_filter module:
https://www.drupal.org/project/wysiwyg_filter
I'm moving this issue over there.

geek-merlinIf this still applies (which i doubt), the issue must lie in the class name regexp which is configurable.

cboyden CreditAttribution: cboyden commentedAccording to the help text for WYSIWYG Filter's allowed class names field:
If you enter a class name that starts with a hyphen, you get an error message like this:
This error isn't coming from Panopoly, it's in the validation provided by wysiwyg_filter.
