Drupal 8.x

Hello,

I installed correctly, at least I think, modules and libraries, to make Slick Carousel work.

But when I set the image field of a content type to "slick image", the little spinning wheel never stops (sorry, I can not attach an image) and the setting is not saved. If I update the page, the field returns to "image".

What to do to solve this problem?

Thank you for your attention :)

In Drupal 8 I create 2 view blocks with a header that contains the following code (Global: Text area) :

First of all, I have to admit it's been a few years since last working with drupal (hence this question).

I am setting up a couple of sites (one being Opigno LMS) for work, which means people from different countries will visit. 
Local language is a must (english set up as deault lang though).

I am looking for input, maybe based on experiences, on how to design/think around this. Info about modules is fine, but firstly I would like info on how to think and plan (probably a number of things to consider).

Have fresh Drupal 8 install with Bootstrap 3 and sub-theme created as per: https://www.webwash.net/getting-started-bootstrap-drupal-8/

Have a couple articles listed in the homepage in <div class="views-row">. As per above tutorial, I'm taking variable from bootstrap/assets/stylesheets/bootstrap/_variables.scss and customizing them in scss/_default-variables.scss

Just trying to put a border on this class but having a hard time figuring out where exactly to do it.

Hello,

how can I make a node available only to unloged users and not available to loged user in other words how can I make a node available only to guest users?

Could anyone please let me know whether there are any articles/tutorials (which discuss SEO consideartions while migrating from Drupal 7 to 8. There are some resources out there. But they talk more about the marketing hype instead of discussing the real  issues.

I am planning to migrating an automotive website to the latest drupal version. It is mainly an news site.

Thanks and regards
