I've tried this

$logo = theme_get_setting('default_logo');

I'm trying to translate my Drupal 7 theme to a Drupal 8 theme.

I followed the instructions to add my CSS and Javascript files by creating the *.libraries.yml.

This is my babol_dp8.libraries.yml file:

Say I have a site and a theme that uses Paragraphs for content creation. I have a basic "Text"-paragraph for inserting formatted text to a node. Sometimes the text needs to be aligned left and sometimes center.

Because most of the text is aligned left, I'd use some sort of option to align it center when needed. For this I have many options to go with:

How we create a Module that display the calendar according to the events in drupal?
