More often than not, templates in a theme share common elements: the header, footer, sidebar, or more. In Drupal, themes created with a Twig template can be decorated by another one. This template inheritance allows you to build a base "layout" template that contains all the common elements of your layout defined as blocks. A child template can extend the base layout and override any of its defined blocks. This helps prevent code duplication, and keeps your theme more organized.
This tutorial is for theme developers who want to reduce code duplication in their themes, or anyone seeking to better understand how Twig template inheritance works. We'll cover:
- What the Twig
blockandextendstags do - An example use-case for template inheritance

Over the years we've developed some techniques for practicing that we wanted to share. At Drupalize.Me we take hugging seriously. In this tutorial we'll look at the art, and science, of giving a good hug. The Merriam Webster dictionary defines the word hug as; squeeze (someone) tightly in one's arms, typically to express affection.
Did you know there are all kinds of different hugs that you can give? In this tutorial we'll look at:
- Defining what a hug is
- Some of the many types of hugs in the world today
- Precautions you may want to familiarize yourself with before hugging
- And the importance of proper technique
Lets go ahead and get started shall we?
