Summary

In the last two chapters on Mastering Drupal 8 Theming, we covered a lot of material. To state that it is just the beginning of all that you can learn about the theming layer would be an understatement. We have only just touched the surface, but hopefully it is enough to spark your interest in taking a longer look at what can be accomplished with Drupal.

Let's review what we covered in this chapter. We began with setting up our local environment for theming, including enabling Twig debugging. From there, we quickly looked at Twig fundamentals that allowed us to inspect, set, and print Twig variables. Finally, we touched on a handful of Twig templates and worked with library assets to use Twitter Bootstrap to build a Jumbotron.

Next, we will be taking a look at extending Drupal.
