Frequently Asked Questions
How is the 'swinging liquid' border animation executed without causing layout shifts or performance bottlenecks?
The animation utilizes an absolute-positioned SVG overlay where the 'd' attribute of the path is interpolated using a spring-physics engine. By animating the SVG path on the GPU composition layer and keeping the input's bounding box static, we avoid triggering expensive browser reflows during the focus state transitions.
What CSS stacking context strategy is used to prevent the backdrop-filter from clipping the multi-layered depth shadows?
We implement 'isolation: isolate' on the component's root container to establish a new stacking context. This ensures that the 'backdrop-filter: blur()' applied to the glass layer does not flatten the Z-index of the 3D parallax elements or truncate the soft outer-glow box-shadows that define the component's depth.
How does the 3D parallax effect calculate mouse coordinates to drive the rotationX and rotationY transforms?
The component uses a throttled mousemove event listener that maps the cursor's 'clientX' and 'clientY' relative to the input's center point into a normalized range of -1 to 1. These values are then passed to CSS custom properties used in a 'transform: perspective(1000px) rotateX() rotateY()' declaration, optimized via 'requestAnimationFrame'.
Given the removal of standard focus lines, how is the 'swinging' animation mapped to accessibility standards for keyboard-only users?
The swinging liquid border serves as the primary visual focus indicator, programmatically linked to the ':focus-visible' pseudo-class. To ensure accessibility, the SVG morphing speed and stroke-width are increased during keyboard focus, and the 'aria-live' attribute is updated to announce the input state to screen readers.
How does the large-scale typography maintain legibility when the glass background passes over high-luminosity image regions?
The typography uses a 'text-rendering: optimizeLegibility' property combined with a subtle 'drop-shadow' filter that acts as a buffer. Furthermore, the glass layer employs a 'contrast()' and 'saturate()' filter within the 'backdrop-filter' shorthand to ensure the white bold text maintains a minimum 4.5:1 contrast ratio regardless of the background content.
