It is the CSS class that generated not compatible with Bootstrap CSS, I expected that I change the class by WYSIWYG editor, but the CSS in the generated HTML was replaced to Publii default, so I cannot utilize Bootstrap class.

This is the HTML I put in the WYSIWYG HTML editor

<p></p>

This is the generated HTML

    <figure class="img-fluid">
        
    </figure>

I cannot figure out how to fit Bootstrap CSS to the generated result.
