白雷 (byakurai) is a light-weight responsive blank starter theme for using various page builders (Block Editor, Elementor, Brizy, Beaver Builder, etc.), without daring to design in detail. Among other things, it is designed to make it easy to design a site using the Block Editor. The block editor currently allows you to place parts of the page itself, from the site name to the post list and comment form. Byakurai can place such blocks in the block editor as well as in template parts such as header and footer by using add-ons, allowing you to design your website freely without being a designer. The concept is the same as Full Site Editing, a new WordPress feature, but fse is still in beta, and byakurai will be able to use plug-ins that do not support fse and will be more stable. This theme is also recommended for those who want to use fse but also want to use the theme editor and other code-based customization features.
