Design & UX guides
Build a shared language for hierarchy, accessibility, and feedback so screens feel intentional, not accidental.
What does mobile-first mean, and what are touch target sizes in UI?
Design for the small screen first, then add complexity; fingers need larger target areas than a mouse pointer.
What are Gestalt principles and how do they apply to interface design?
Proximity, similarity, closure: the brain groups visuals into meaning before you add a single word of copy.
What is microcopy, and how do labels and errors help or hurt the experience?
The small string next to a field, on a button, or in a toast: it should be clear, specific, and human, not all caps Lorem.
What is usability testing and what do moderated sessions and tasks measure?
Watch real people try to do jobs with your product: task success, time, and where they get stuck, not a beauty contest.
What is progressive disclosure in interface design?
Show what most people need first; reveal power features on demand, not everything at once.
What is Fitts's law and how does it apply to button size and distance in UIs?
Bigger, closer targets are easier to hit; place frequent actions in easy reach, edge targets can be 'infinite' on screen edges.
