As browser ecosystems expand into three-dimensional hardware (like spatial headsets and augmented lenses), web styling is undergoing a major shift. The traditional flat layout is giving way to overlapping depth and floating components. Web designers are no longer constrained by rigid two-dimensional containers; instead, they must consider how light, shadow, and depth interact to guide the user's attention.

1. Enforcing Depth via Glassmorphism

To simulate realistic layers, we use translucent materials with blur filters rather than solid fills. In vanilla CSS, this is achieved using the `backdrop-filter: blur()` property. This allows elements in the background to remain visible but obscured, creating a natural visual hierarchy and a sense of physical space.

"Visual depth isn't just an aesthetic preference — it is a critical navigation aid in spatial environments."

2. Optimizing Touch Targets and Margins

Because users interact with spatial UIs using hand gestures and eye tracking, button sizes and padding must be adjusted. Touch targets should be at least 48px to prevent accidental clicks. We also increase the margins between interactive elements to ensure a clean, uncluttered layout and prevent overlapping states.
