Summary
In this chapter, we discussed a theme’s configuration, how to add a form to input it, and how to use it in Twig and JavaScript files.
Configuring a theme is way more helpful when we create a set of sub-themes from a parent one, and in the last section of the chapter, we saw how to define a sub-theme and which information is inherited from the parent one.
However, a beautiful and catchy theme may not be useful if it’s not performant and accessible, so in Chapter 14, Improving Performance and Accessibility, we’ll discuss those two essential requirements.
