Drupal 8.x

I've made a custom block type and I'm trying to make a template for it that works for all instances of it.  I've added suggestions like this:

Hello, 

 Requirements:

Have a form for homeowners to enter the property address. 

As they are entering the address, I like to make a call to Zillow and redfin to return the square footage and Zestimate based on the given address. 

I will use the numbers to calculate the offer price. 

I am not sure where to start and how to do it. 

Please let me know if you can provide me some design/implementation tips. 

Thanks! 

In a Movimenti content type, I have several fields one of these is an entity references, linked to an Anagrafica Dipendente data content type.
The field is enhanced by a function. In form_alter I need to take a field of the Anagrafica Dipendente.
I saw the array of the field and was thinking of using this code
     $id = $form['field_dipendente']['widget'][0]['target_id']['#default_value']['id'];
But the error returns to me
 Error: Cannot use object of type Drupal\node\Entity\Node

By clicking at the profile page at one of the submissions it takes me to a unstyled page which has not the theme of the whole site.
How can I them this site in the same way like the whole site?

Hi guys

Looking for a Javascript expert who can hide the 'Next' button on an Opigno Install Drupal 8.  Bonus if you are familiar with Opigno as we are also looking for long term support.

The button will become visible once a person has completed the embedded SCORM package.

Here is a summary of the issue:

I downloaded these two modules:

https://www.drupal.org/project/ckeditor_font
https://www.drupal.org/project/colorbutton

Before I enable them the content is always shown.

When I enable them the content has gone.

Have a look at:
