Drupal 8.x

I'm working my way through 'Learning Drupal 8' Abbot & James and I'm stuck.

After describing how to create a block view, it says, place the block on the Services Page (a page made earlier)

How can I place a block on a page?

Thanks

I'm working my way through 'Learning Drupal 8' Abbot & James. I'm stuck on chapter 7.

The chapter works on View Modes (Default, Teaser, RSS etc) and enables Full Content View mode.

After making some changes it instructs to look at a full view of an article node which I assume means to look at an article in Full Content View mode.

How can I do this?

In general, how can I quickly switch between view modes to see what they look like?

Thanks

I would like to incorporate the image properties element as seen in this demo: http://sdk.ckeditor.com/samples/fileupload.html#uploading-dropped-and-pa...

Go to link. Find Editor. Click Image button. You can see two options: "Image Info | Upload"

First off, the basic CKEditor in D8 does not allow me to set height and width as it does in this very body field

Currently I have simple view that is used on the main page. In includes nodes of custom type. That's great. But now I need to do something different.

Consider I have following structure:

-----View-----
-------Node 1--------
-------Node 2--------
-------Node 3--------
-------Node 4--------
-----End View-----

But I want to have the structure like that:

Hello !
I have created a nodes view and I would like to put a label ("New") to the nodes created in the last 30 days.
I try to do it with Twig, but without success so far ...

Here's where I am (in a custom text) :

{% if created <= 'now'|date('-30days') %}

<p><span class="uk-label new-label">New</span></p>

I want to move an existing site to Drupal 8, and wonder how to represent mass data: using existing data base tables, or using Drupal content types?
