Drupal 8.x

So I am using Drupal 8.7.8 and I have Layout Builder enabled for one of my content types. I am making custom layouts using the Layouts API. This is all working great and doing what I need. However, I am now trying to add an "inner div" inside a column surrounding the content for that column, and as soon as I do that, I am no longer able to drag and drop blocks in layout builder.

This is what I have in my "layout--two-col.html.twig" that works:

I have changed to my own loga, a .jpg Picture 321x256 pixel one. After saving and publishing there is no logo...HELP! My site is https://brintemotion.com

My default language shall be English but I would like to have Another Three on the same site, i.e. French, German and Swedish. Is that possible (on any theme)?

I have a View and I am trying to add new filters and then add those filters to a new filter group. I can create the filters but I can't work out how to add a filter group

My main language on Drupal will be English. Is it possible to add more as user choices? In my case I would like to add French, German and Swedish. 

Hi,

I am trying to place a block on my custom page. The code in my Controller is placing the blocks in the 'content' region. How can I make the blocks appear side by side?

I have pasted the code, but it does not seem to work. Actually I want to show the two blocks side by side. Please let me know

<?php

namespace Drupal\heritage_ui\Controller;

use Drupal\Core\Controller\ControllerBase;
use Drupal\node\Entity\Node;
