CSS Architecture

Scalable, token-driven CSS that supports design systems and engineering teams.

Design tokens and theming

:root { 
    --color-bg: #050816;
    --color-surface: #0b1020;
    --color-accent: #F15A22;
    --color-accent-soft: rgba(241, 90, 34, 0.12);
    --color-primary: #0a0e27;
    --color-text-main: #f5f7ff;
    --color-text-muted: #9ca3af;
    --radius-lg: 20px;
    --shadow-soft: 0 18px 45px rgba(0,0,0,0.55);
    --transition-fast: 0.18s ease-out;
}

body {
    background: radial-gradient(circle at top, #111827, #020617 55%, #000);
    color: var(--color-text-main);
    font-family: system-ui, -apple-system, BlinkMacSystemFont, "Segoe UI", sans-serif;
}

.card {
    background: linear-gradient(145deg, rgba(15,23,42,0.96), rgba(15,23,42,0.65));
    border-radius: var(--radius-lg);
    box-shadow: var(--shadow-soft);
    border: 1px solid rgba(148,163,184,0.15);
}

Layout utilities

.stack {
    display: flex;
    flex-direction: column;
    gap: 1.25rem;
}

.cluster {
    display: flex;
    flex-wrap: wrap;
    gap: 0.75rem 1.25rem;
    align-items: center;
}

.grid {
    display: grid;
    gap: 1.75rem;
}

.grid.two-cols {
    grid-template-columns: repeat(2, minmax(0, 1fr));
}

.grid.three-cols {
    grid-template-columns: repeat(3, minmax(0, 1fr));
}

@media (max-width: 900px) {
    .grid.two-cols,
    .grid.three-cols {
        grid-template-columns: minmax(0, 1fr);
    }
}

Component-level styling

Practical CSS for cards, badges, tables, and interactive states.

Badges and chips

.badge {
    display: inline-flex;
    align-items: center;
    gap: 0.4rem;
    padding: 0.2rem 0.7rem;
    border-radius: 999px;
    font-size: 0.75rem;
    letter-spacing: 0.03em;
    text-transform: uppercase;
}

.badge--success {
    background: rgba(34, 197, 94, 0.12);
    color: #4ade80;
    border: 1px solid rgba(74, 222, 128, 0.5);
}

.badge--critical {
    background: rgba(248, 113, 113, 0.14);
    color: #fca5a5;
    border: 1px solid rgba(248, 113, 113, 0.6);
}

Interactive table rows

.metrics-table tr {
    transition: background-color 0.18s ease, transform 0.18s ease;
}

.metrics-table tr:hover {
    background-color: rgba(15, 23, 42, 0.9);
    transform: translateY(-1px);
}

Glass cards on gradient

.glass-card {
    position: relative;
    border-radius: 24px;
    background: linear-gradient(145deg, rgba(15,23,42,0.9), rgba(15,23,42,0.65));
    border: 1px solid rgba(148,163,184,0.25);
    backdrop-filter: blur(18px);
}
