WordPress 5 gives themers more control over the appearance of content and provides us with tools, both new and familiar, that allow us to integrate our theme with the new Gutenberg editor. This practical presentation will demonstrate how to extend a theme or child-theme for the content editing experience, an approach to theming blocks and taking advantage of Gutenberg’s features, and offer an example workflow using Vagrant and VVV for local development and Sass for structuring and generating CSS files. This presentation will also address the case where a site is using both Gutenberg and the Classic Editor plugin. Code examples used in the presentation will be published to GitHub.
