Drupal 8.x

so I got media module and media library module setup and I have the media library button in CKeditor.

how to customize the display of embedded media?

as of now, when I insert a picture, it just inserts a full width picture, there are no options to adjust size, no option to link to the original picture, etc.

similarly, when I insert a PDF, it just shows an ugly full-width black-and-white "document" icon, no link to original document, nothing.

also no way to add a custom style

did I miss some steps in the configuration?

One of my sites has out-grown bluehost so I wanted to try out Amazon's AWS, starting with Lightsail.   The default templates make it easy to set up a legacy architecture with Maria.  I want to user composer-recommended as that is how my site is currently designed.  I've almost been able to install a site except for the mysql connection.  I created a LAMP instance and installed the basic Drupal site code with composer. I have not been able to link a database to the install, however.

My custom block gets multiple nodes and uses ViewBuilder to render these nodes. The node titles in this block are linked to the canonical route. That works for a default but my customer wants to link to an external link if that attribute has that value. So I'm incorporating TrustedCallbackInterface in my custom block to build a pre_render callback. But I'm getting an unexpected error:

Parameter 1 to Drupal\mymodule\Plugin\Block\MyBlock::changeUrl() expected to be a reference

Here's an excerpt of my custom block

Hello,

Config > Meta tag > Global or frontpage or content > browse available tokens > Does not show any node tokens. 

I googled but did not find any answer. 

Thanks!

I am making a website where I have a number of expert bloggers. A user can then subscribe to one or more expert's blog. Users without a subscription to the author should not be able to see the content.

I need a few good suggestions on how to control the permissions.
