In my custom Drupal 8 theme, for all regions of my page, there is HTML looking like:
<div class="block-region-xxxx"></div>
where xxxx is the region name.
There are also empty 's rendered around my blocks.
This is my block.html.twig
{% block content %}
{{ content }}
{% endblock %}
as you see, no divs there.
Here's my theme.info.yml , region part:
regions:
header: Header
hero: Hero
help: Help
top: 'Page Top'
content: Content
sub: 'Sub Content'
bottom: 'Page Bottom'
footer: Footer
Here's a screenshot of the actual HTML tree rendered:
essentially I'd like to remove everything between the .row and the .col..
