Drupal 8.x

Hello, I have a view where I have blocks of data in it. This is a search view and in this I have to display data in blocks. I would like to know if there is a way to add custom block with view fields inside it. Is it possible? My view looks as below:

All the fields in this picture are view fields. However I want to show the section like a custom block and wire up the view fields into that custom block. Is that possible?

I am having trouble with what I hope if just the final step of customizing my theme.

In my theme, I want to tweak the way the article-teasers are shown.

I can see an existing twig called "field--node--field-image--article.html.twig" and

I THINK I want to just copy it to a new file named "field--node--field-image--article--teaser.html.twig" and make my modifications.

I did that and here is just a snippet of the change

I have to install, with composer, the Multi Site with D8 locally on XAMPP.
I have read various articles but I have difficulties when I install the first site I get the error page not found
In the various examples seen, someone installs it on the main folder, while others do it only in the two folders created in sites.

Given the amount of advice and material, I find myself in difficulty. A help?

Hi,

I added a block right after the menu. However, it is showing lots of empty space. Is there any way to get rid of that space?

I added both the images in one block. I am not sure whether that is the right way to do so.  While uploading the images, I simply set them as left and right-aligned.  Now, there is a lot of space between the two images.  How to fill that area if I do not want to increase the width of these images.

Is there anyone who can help with a link to the tutorial on how to integrate the juicebox and media module?

Thanks
Willy
