You’ve heard a thousand times that “details matter,” but front-end development is the discipline where this cliché becomes a law of physics.

Misaligned icons, inconsistent spacing, unclear error states—individually, they’re tiny inconveniences. But together, they tell the user something fundamental: this product wasn’t designed for me.

Great UI is rarely the result of dramatic redesigns. It’s the sum of small, thoughtful decisions—spacing, microcopy, transitions—that collectively shape trust.

Pixels, like dollars, compound. And the best developers invest them wisely.
