I'm not a huge fan of having to add this much CSS to provide defaults that can overcome styles in core. If anyone has any ideas on a better approach, I'd be happy to evolve this one.

Without these tweaks the user has to set multiple fields before a border shows up. Even now the default border color is currentColor so when the background is white and the button text is white, the border isn't really visible.

It doesn't seem like we need to replicate this in editor.scss and styles.scss - if I removed this section from here the CSS from styles.scss seemed to be applied in the editor and the frontend? I did a fresh build and a hard reload to make sure it wasn't just a case of the editor styles being cached.

We do need to add this CSS to overcome core's theme.json button element styles which reset border-width to 0.

The theme.json styles get the .editor-styles-wrapper class prefixed to their selectors in the editor. As a result, those styles override the styles in the frontend style.scss.

Without these styles, a user needs to adjust the border width before they can see any border.

To witness this behaviour:

  1. Delete or disable the styles here in the editor.scss file
  2. Make sure you don't have any core/button styles in your theme.json
  3. Edit a post and add a button
  4. Select the button and select only a border color
  5. Note that there is no visible border due to the core theme.json border width reset for button elements.

Thanks for the extra detail - I was adding the border width and then the color so wasn't picking this up - if I had read back through the old comments I would have picked all that up - sorry for wasting your time here!

I have modified the comment to specify this detail like the one in style.scss does.
