WordPress Theme Development

Anyone can install a WordPress theme. But developers who can build custom themes from scratch are in a completely different league — and they command completely different rates. If you want to go from WordPress user to WordPress developer, this is the course that makes that happen.

This certificate course teaches you how to build professional, fully custom WordPress themes using PHP, HTML, CSS, and the WordPress template hierarchy. By the end, you will have a theme you built yourself — one that you can use for client projects, sell on ThemeForest, or use as the foundation for a premium theme business. Every concept is taught by Debasis Bhattacharjee, a working Software Architect with 20+ years of experience building and shipping real web products.

Why Custom Theme Development Is a High-Value Skill

Pre-built themes are everywhere. What clients actually pay premium prices for is something tailored specifically to their brand — a theme that no one else has, built exactly to spec. Custom theme developers charge significantly more than those who just configure existing themes, and the work is far more interesting and rewarding.

Beyond client work, the WordPress theme marketplace on ThemeForest generates millions of pounds in sales every year. Theme developers who understand what buyers want can build a genuine passive income stream.

What You Will Actually Build

• Project 1 — Starter Theme from Scratch: A clean, minimal WordPress theme built entirely by hand — no frameworks, no page builders. Full template hierarchy, custom post type support, and widget areas.
• Project 2 — Business/Agency Theme: A professional multi-layout theme with a homepage template, blog layout, portfolio section, and custom theme options panel.
• Project 3 — ThemeForest-Ready Theme: A polished, documented theme built to ThemeForest submission standards — complete with a demo, documentation, and licensing setup.

What You Will Learn

• WordPress Template Hierarchy: How WordPress decides which file to load — and how to use that system to control every page on your site.
• PHP for WordPress: WordPress functions, hooks, filters, actions, the Loop, custom queries, and plugin API integration.
• Custom Post Types and Taxonomies: Building portfolio, testimonial, and service post types with custom fields and custom archive templates.
• Theme Options and Customiser: Building a live theme customiser panel with colour pickers, font selectors, and layout controls.
• Child Themes: Properly extending existing themes without breaking updates.
• Theme Packaging and Distribution: Preparing your theme for ThemeForest, writing documentation, and setting up licensing.

Who This Course Is For

This course is designed for people who already know basic HTML, CSS, and some PHP — or who have completed the Full Stack Web Development Diploma. If you are a WordPress user who wants to go deeper, a developer who wants to add theme development to your skill set, or someone who wants to build and sell themes, this course is for you.
