HTML5 Semantic Elements

外掛說明

The HTML5 Semantic Elements plugin introduces two custom Gutenberg blocks — Article and Aside — that allow you to structure your WordPress content with proper semantic HTML5 elements.

Use the Article block for self-contained content such as blog posts or news items, and the Aside block for related or supplementary information such as sidebars, pull quotes, or callouts.

These semantic elements improve both SEO and accessibility by clearly defining the roles of different content sections.

How to Use

Adding Blocks

1. Edit any post or page in the block editor
2. Click the “+” button to add a new block
3. Search for “Article” or “Aside”
4. Click the desired block to insert it into your content
