Theme development

the BootstrapCarousel locates in the following folder. As I know in drupal 7 I could use bootstrap Carousel in a View, but in drupal 8, how I could leverage this plugin in my website?

bootstrap -> src -> Plugin -> Preprocess -> BootstrapCarousel.php

class BootstrapCarousel extends PreprocessBase implements PreprocessInterface

Hello,

I've been following this guide on how to register layout pages https://www.drupal.org/node/2578731

However, after uploading my_theme.layouts.yml file I receive the following message 'The website encountered an unexpected error. Please try again later.'

My file structure looks like this...

themes/custom/qc/qc.layouts.yml
themes/custom/qc/templates/home/homepage.html.twig
themes/custom/qc/templates/home/homepage.css
themes/custom/qc/templates/home/homepage.png

I just started working with Drupal one week ago.

I already searched 3 days and can't find a solution.

My website shows a thumbnail and the first lines of text (see http://www.denationalezorgcourant.nl). As you can see when there is no image the text doesn't fill up the whole space. I tried different things within the CSS but nothing works.

Hope someone knows the answer, I'm going crazy.
