How often do we realize the actual meaning of terms before we use them?

We throw around words like DP, 720p, 1080p, or drop shadows without thinking twice. But every term carries a deeper logic, a purpose beyond just numbers on a screen. DP (density-independent pixels) isn’t just a unit—it’s a way to ensure designs feel the same across devices, no matter the screen size or resolution. A button on one phone should never feel smaller or bigger on another—it should just be. Design isn’t about placing elements; it’s about creating consistency, clarity, and a seamless experience that feels right, no matter where it’s seen.

The same applies to shadows. They aren’t just decorations; they give meaning. A soft shadow can make a button feel approachable, while a deeper one makes it stand out with intent. In Material Design, elevation isn’t just about looks—it’s about perception. A raised button isn’t just higher, it’s more important. Every element we design has a purpose, whether we realize it or not. The magic of design lies in understanding the invisible rules shaping what people feel—because great design isn’t just seen, it’s felt.
