Strategic Guide to Custom Theming in Drupal from Attico

Staff Reporter

This in-depth article by Yauhen Bayeu reframes Drupal theming as a foundational architectural task—not just visual design. Bayeu argues that custom themes should serve performance, scalability, and editorial experience, treating theming as infrastructure rather than decoration. The piece outlines three theming paths—base themes, visual generators, and scratch-built themes—recommending the latter for production-grade flexibility and precision.

The process emphasizes strategy before markup, advocating early stakeholder involvement to align frontend structure with business and content goals. Theming should prioritize reusable components, performance from the outset, mobile-first principles, and an editor-friendly backend using tools like Layout Builder and Paragraphs. Long-term success also hinges on testing, documentation, and maintenance. Bayeu positions theming as a critical business decision, not a post-development add-on.
