Atomic Century Login
Live Preview
A sophisticated login component inspired by Mid-Century Modern aesthetics. It features a warm cream and charcoal palette with pops of mustard yellow and teal. The design utilizes organic-geometric shapes, specifically a custom-drawn starburst SVG and an asymmetrical 'Bertoia' style card radius. Typography is handled via Jost for a clean, geometric feel that echoes 1950s graphic design while remaining fully accessible and responsive for modern devices.

Frequently Asked Questions
How is the asymmetrical 'Bertoia' style border-radius implemented to ensure the organic shape doesn't interfere with standard focus states?
The component utilizes a complex 8-value border-radius property (e.g., 60% 40% 30% 70% / 50% 30% 70% 50%) applied to the main container. To prevent the focus rings of the Jost-styled inputs from being clipped by the container's overflow:hidden, we utilize a padding-buffer strategy or 'outline-offset' on the input elements to ensure WCAG 2.1 compliance while maintaining the 1950s silhouette.
Does the 500px desktop height constraint utilize CSS Scroll Snap or a flex-shrink logic when additional validation messages are rendered?
To maintain the strict 500px aesthetic, the component uses a 'grid-template-rows: min-content 1fr min-content' layout. When validation errors appear, the central form area utilizes an internal overflow-y: auto with a custom-themed charcoal scrollbar, ensuring the 'Bertoia' card dimensions remain static and visually balanced within the viewport.
How can the custom SVG starburst brand mark be programmatically recolored for different 'Atomic' sub-brands without modifying the source SVG file?
The starburst is injected as an inline SVG where the path's fill property is set to 'currentColor'. This allows developers to pass a CSS variable (e.g., --brand-accent) to the parent container, which then propagates the mustard yellow or teal hue down to the SVG elements via standard CSS inheritance.
What specific easing function is used for the form submission micro-interaction to replicate 1950s-era kinetic typography?
The submission animation employs a custom cubic-bezier(0.34, 1.56, 0.64, 1) 'back-out' easing function. This creates a slight overshoot effect on the submit button's scale and the starburst's rotation, mimicking the physical 'snap' seen in mid-century mechanical displays and animated title sequences.
Is the 1950s wallpaper-inspired background pattern rendered via a high-resolution bitmap or a procedural CSS-generated pattern?
The background pattern is a lightweight, repeatable SVG pattern defined within a CSS paint worklet or a base64 encoded background-image. It uses a mix of 'multiply' and 'screen' blend modes against the cream (#F5F5DC) background to ensure the pattern remains subtle and doesn't create visual noise that would impair the readability of the Jost typeface.
