UI Design: Interfaces That Work
Last updated: March 2026 · Reading time: 4 minutes
UI design is not about making things pretty. It is about making things work. A beautiful button that nobody finds is worse than an ugly button in the right place.
Good UI design is invisible: users achieve their goal without thinking about the interface.
What Good UI Design Achieves
Visual hierarchy: size, color and placement signal what is important. CTAs stand out. Secondary actions recede. Users know immediately where to look.
Consistency: same elements, same behavior everywhere. A button that looks the same always does the same thing. This reduces learning effort.
Accessibility: sufficient contrasts, clear focus states, readable font sizes. Good UI design is accessible by default.
Responsive design: the interface adapts to every screen size. Mobile is not a shrunk desktop but its own design challenge.
From UI Design to Drupal Theme
arocom translates UI designs into Drupal themes that are pixel-perfect and performant. The design agency delivers the visual language, arocom implements it in Twig templates, CSS and JavaScript.
The challenge: UI design must work within Drupal's architecture. Content types, views and layout builder set the framework. Good implementation means: the design works with Drupal, not against it.

What is the difference between UI and UX design?
UI design determines how the interface looks and behaves — colors, typography, buttons, layouts. UX design determines how the overall experience feels — information architecture, user flows, content strategy. Both are inseparable in practice.
Do we need a separate UI designer for our Drupal project?
Not necessarily. arocom works with design agencies in the co-pitch model. The design agency delivers the UI, arocom implements it. For smaller projects, arocom creates UI designs based on established design systems.
