When designing a website, an app, or portfolio, two things will always matter: the user and experience. A brand’s success in the digital space depends on whether users feel good or bad about it. The keyword here is “feel.” The emotional and intellectual response depends not only on how a brand works or how it looks, but how it feels.
In a design composition, the visual weight of an object refers to how well it draws attention to itself compared to other components of the composition. The "heavier" the object is, the more eye-grabbing it is.
