Tero Elonen developed reusable front-end patterns and standardized visual templates for special pages in the City-of-Helsinki/drupal-hdbt repository, focusing on consistent presentation for error, maintenance, and login pages. Using CSS, SCSS, and Twig templating, Tero improved figure caption alignment to enhance readability and visual consistency across desktop views. He also addressed localization gaps by updating the Finnish translation in the City-of-Helsinki/drupal-helfi-etusivu repository, ensuring accurate UI text for Finnish users. The work demonstrated a thoughtful approach to maintainability and cross-repository collaboration, resulting in more efficient updates and a unified user experience across City of Helsinki’s Drupal-based sites.
