Designing Custom Sites Using Child Themes in WordPress and CSS
Child themes are your safety net—modify WordPress sites without risking core updates that wipe your changes. This course teaches you to build custom designs using child themes and CSS, a skill that separates competent developers from those constantly firefighting broken sites.
AIU.ac Verdict: Ideal for WordPress developers and designers who want to customise sites properly and avoid the nightmare of lost work during updates. The 2-hour format is tight, so you’ll need foundational WordPress knowledge—this isn’t a WordPress 101 course.
What This Course Covers
You’ll learn the architecture of child themes, why they matter for maintainability, and how to structure them correctly. The course covers CSS customisation techniques, overriding parent theme styles safely, and debugging common inheritance issues. You’ll work through hands-on scenarios: modifying layouts, adjusting typography, and adding custom functionality without touching the parent theme.
Beyond theory, Jay Boucher walks you through real-world workflows: setting up child themes in local environments, using browser DevTools to identify selectors, and deploying changes to live sites. You’ll understand when to use child themes versus plugins, and how to document your customisations so future developers (or you, six months later) can maintain them.
Who Is This Course For?
Ideal for:
- WordPress developers: Need efficient, update-safe customisation techniques to deliver client work faster without technical debt.
- Freelance web designers: Want to move beyond page builders and control design at the CSS level while protecting client sites from breaking.
- Agency developers: Building repeatable processes for multiple WordPress projects and need standardised child theme workflows.
May not suit:
- WordPress beginners: You’ll need solid grasp of WordPress admin, theme structure, and basic CSS before this course adds value.
- Non-developers using page builders only: This course assumes comfort with code and file structures; visual-only builders won’t prepare you for this content.
