WordPress Theme — WordPressテーマとは？

WordPressテーマはサイトのビジュアルデザインを決定します。クラシックテーマとブロックテーマの違いを解説します。

Definition

A WordPress theme is a collection of files (PHP, CSS, JavaScript, theme.json) that define the design and structure of a WordPress website. Themes control the header, footer, page templates, color palettes, and typography — independently of the actual page content stored in the database.

Classic themes vs. block themes

Classic themes use PHP templates (header.php, footer.php, single.php) and the WordPress Customizer. Block themes (since WordPress 5.9) use HTML files with block markup and theme.json for global styles. Block themes support Full Site Editing — classic themes do not.

Popular WordPress themes

The most popular free block themes include Twenty Twenty-Four and Twenty Twenty-Five. Premium themes are dominated by Astra, Kadence, GeneratePress, and OceanWP — they are lightweight and compatible with all common page builders.

Themes and anipage.io

anipage.io generates page content (Gutenberg blocks, Divi modules, or Elementor templates) — not a complete theme. The generated pages work with any compatible WordPress theme. For Gutenberg exports, we recommend a lean block theme like Twenty Twenty-Four or Kadence.
