Building a WordPress Theme from Scratch — With a Little Help from AI

Spread the love

What happens when a developer who lives in the world of Javascript, browser extensions, NodeJS apps and static site generators suddenly needs a WordPress theme?

Spoiler: curiosity happens. And a weekend disappears into a rabbit hole of PHP, CSS grids, and AI-assisted tinkering.


The Setup

I wanted a theme for my Nerd @ Work blog that felt like my code editor—quiet, focused, nothing shouting for attention.
I didn’t want sliders, megamenus, or shortcodes that feel like they escaped from 2013. Just a clean layout, sharp typography, and a dash of modern responsiveness.

But I’d never actually built a WordPress theme. So I did what any developer does in 2025: I asked ChatGPT to teach me.


ChatGPT: My WordPress Co-Pilot

I started with a simple prompt:

“I need a minimal WordPress theme with multi-level navigation, sidebar, and custom header support.”

ChatGPT generated the core pieces—style.css, index.php, functions.php, and the usual suspects.
It explained the template hierarchy like a patient mentor with infinite caffeine. I learned enough to assemble a working skeleton in under an hour (ehm 10 minutes…).


Cursor: The Finishing Touch

Once the bones were there, I switched to Cursor, the AI-powered code editor, for refinement.

Pagination needed flair; Cursor wrote me a CSS hover effect that actually sparked joy.
The post navigation cards? Cursor.
The mobile menu with proper ARIA support? Cursor again.

Together, they made the theme feel hand-crafted—just… with more electrons involved.


The Result: Minimal-blog-by-enreeco

A theme built for writers who’d rather tweak code than settings.

Design philosophy
Monochrome palette. Thoughtful spacing. No visual clutter.

Core features

  • Responsive grid layout (CSS Grid + clamp-based typography)
  • Three-level navigation
  • Custom header and logo
  • Styled pagination and post navigation
  • Search and comments integration
  • Translation-ready, accessible HTML

Under the hood

  • Sanitized and escaped PHP everywhere (because we’re grown-ups)
  • Customizer support for footer text
  • A Node.js build script that zips the theme cleanly, no node_modules in sight

Lessons Learned

  • AI isn’t a crutch—it’s a teacher. ChatGPT explained every file and function until WordPress made sense again
  • Cursor is the laser cutter—precise and ruthless with CSS and PHP bugs
  • Iteration beats inspiration. The theme evolved through a steady rhythm of prompt → edit → test → refactor

What used to feel like black-box PHP turned into an open book. Turns out, WordPress isn’t the dinosaur—it’s the terrain. You just need better tools to explore it.


Try It Yourself

The finished theme now powers this very blog.

Or checkout the GItHub Repository (use the simple build script to generate the zip): https://github.com/enreeco/wordpress-minimalist-template-enree?tab=readme-ov-file

It’s lightweight, fast, and as minimal as its name promises.


Crafting something new inside an old ecosystem felt weirdly poetic—like teaching a classic instrument a new tuning. And it’s proof that a weekend, two AIs, and a bit of stubborn curiosity can still make something worth shipping.
