- What a WordPress theme is and what types exist in 2026.
- Creating a block theme (the current standard) with Claude Code.
- Installing and testing it on a local WordPress setup.
Key concepts
Step by step
Create the theme folder and start Claude Code:
cd ~/proyectos-ia mkdir tema-wordpress cd tema-wordpress claude
Install and test
The README will tell you how, but in essence: zip the theme folder into a .zip file and upload it in WordPress under Appearance → Themes → Add New → Upload. Activate it.
If something goes wrong
- The theme doesn't appear when you upload it — check that the .zip contains the files at the root level and that style.css exists with the theme header.
- It looks broken — paste the error or a screenshot into Claude Code; it's usually a misreferenced template.
- I can't edit visually — confirm it's a block theme and that your WordPress is up to date.
Practice challenge
Ask Claude Code for a dark mode variation of the theme and a reusable section pattern (for example, a "testimonials" block) that you can insert on any page.
