Overview of this book

Drupal 8 is an open source content management system and powerful framework that helps deliver great websites to individuals and organizations, including non-profits, commercial, and government around the globe. This new release has been built on top of object-oriented PHP and includes more than a handful of improvements such as a better user experience, cleaner HTML5 markup, a new templating engine called Twig, multilingual capabilities, new configuration management, and effortless content authoring. Drupal 8 will quickly become the new standard for deploying content to both the web and mobile applications. However, with so many new changes, it can quickly become overwhelming knowing where to start and how to quickly. Starting from the bottom up, we will install, set up, and configure Drupal 8. We’ll navigate the Admin interface so you can learn how to work with core themes and create new custom block layouts. Walk through a real-world project to create a Twig theme from concept to completion while adopting best practices to implement CSS frameworks and JavaScript libraries. We will see just how quick and easy it is to create beautiful, responsive Drupal 8 websites while avoiding the common mistakes that many front-end developers make.

Drupal provides us with multiple ways to address templating a specific page. As we saw when we created our homepage, we can take advantage of Twig debugging to identify which templates are being output. The same is true for our interior pages. If we navigate to the About Us page and inspect the markup we can identify that Drupal is using the default page.html.twig template, as shown in the following image:

This template is clearly different than the page--front.html.twig template we created earlier, which explains why some of our page elements are missing. However, this is a good example of how we can use different Twig templates to control the markup.

Begin by following these steps:

  1. Navigate to the core/modules/system/templates folder and copy page.html.twig.

  2. Place the copy within our themes/octo/templates folder.

Make sure to clear Drupal's cache and refresh the About Us page. If we inspect the page again, we will note that our new template is being used...
