Use inline style in CKEditor 5

drush cex <the ID of your text format> + drush cex <the ID of your text editor>

With enabled "Limit allowed HTML tags and correct faulty HTML" filter you can't have style attribute.

We use the style plugin to add inline styles, like this:

span.highlight|Highlight

Saving the editor configuration throws the following error

The Style plugin needs another plugin to create <span>, for it to be able to create the following attributes: <span class="highlight">. Enable a plugin that supports creating this tag. If none exists, you can configure the Source Editing plugin to support it.

Which is correct, because we do not have a plugin defining that we can use span tags.
The approach for adding the source editing plugin works, and allows me to add the styling i want.

However, i do not really like having to add the Source editing plugin for this.

I can solve the problem in a module by adding this configuration inside a .ckeditor5.yml file:

ckeditor5_span_span:
  ckeditor5:
    plugins:
      - essentials.Essentials
  drupal:
    label: Span
    library: core/ckeditor5.essentials
    admin_library: ckeditor5/internal.admin.essentials
    elements:
      - <span>

Is allowing span tags something we want to do in core, or would it be best to create a contrib module for this?

That's the only way, sorry.

Clever work-around for your particular use case! 😄 But that now means you can create <span> tags using the UI. Which is not actually true.

In fact, most people seem to be really annoyed by <span> in general — we used to be more pragmatic but got a lot of backlash. See #3273983: Do not assume that plugin supporting also supports in SourceEditingRedundantTags and upgrade path → .

or would it be best to create a contrib module for this?

I think an ckeditor5_implicitly_allow_spans contrib module would make sense, yes!
