/* aporia.gr — one stylesheet for the whole site * * Three ideas hold it together: * SQUIRCLES every interactive surface is a superellipse, not a rounded rectangle. * corner-shape does it properly where it exists; a generous radius is the * fallback, so the shape language survives in older browsers. * GLASS panels are translucent over a soft page wash, blurred and saturated. * Without the wash there is nothing to blur, so the wash is not decoration. * LEVEL --accent is set by data-level on , one colour per class, warm at * Δημοτικό and deep at Λύκειο. Every value below clears 4.5:1 for white * text on it and for itself as text on the page. Measured, not picked. */ :root{ --paper:#eceff3; --surface:#fff; --surface-2:#f4f7f9; --sunk:#dde5ec; --ink:#0f1c29; --ink-2:#4a5c6e; --ink-3:#738799; --rule:#ced7e0; --rule-soft:#e3e9ef; --blue:#014488; --on-blue:#fff; --blue-soft:#e7eef6; --green:#2c6b4f; --green-soft:#e6f2ec; --red:#bd3228; --red-soft:#fbeceb; --shadow:0 1px 2px rgba(15,28,41,.05),0 12px 34px -18px rgba(15,28,41,.24); --f-display:"Literata",Georgia,serif; --f-body:"Commissioner","Helvetica Neue",Arial,sans-serif; --f-mono:"JetBrains Mono",ui-monospace,Menlo,monospace; /* squircle radii */ --r-xs:8px; --r-sm:12px; --r-md:16px; --r-lg:22px; --r-xl:30px; --r-pill:999px; /* glass */ --glass:color-mix(in srgb,var(--surface) 62%,transparent); --glass-2:color-mix(in srgb,var(--surface-2) 64%,transparent); --glass-sunk:color-mix(in srgb,var(--sunk) 46%,transparent); --hair:color-mix(in srgb,var(--ink) 10%,transparent); --hair-2:color-mix(in srgb,var(--ink) 16%,transparent); --blur:saturate(185%) blur(20px); /* the bluish hover */ --tint:color-mix(in srgb,var(--blue) 15%,transparent); --tint-2:color-mix(in srgb,var(--blue) 26%,transparent); --ring:color-mix(in srgb,var(--blue) 42%,transparent); --glow:0 10px 28px -12px color-mix(in srgb,var(--blue) 60%,transparent); --accent:var(--blue); --ease:cubic-bezier(.32,.72,0,1); } @media (prefers-color-scheme:dark){:root:not([data-theme="light"]){ --paper:#0a121a; --surface:#111c26; --surface-2:#16222e; --sunk:#0d1720; --ink:#dde6ef; --ink-2:#9db0c3; --ink-3:#6d8299; --rule:#25374a; --rule-soft:#1c2b38; --blue:#5a9ee0; --on-blue:#08131f; --blue-soft:#13202d; --green:#5dbd90; --green-soft:#12211b; --red:#ff7063; --red-soft:#2a1a1a; --shadow:0 1px 2px rgba(0,0,0,.4),0 14px 36px -20px rgba(0,0,0,.9); --glass:color-mix(in srgb,var(--surface) 58%,transparent); --glass-2:color-mix(in srgb,var(--surface-2) 62%,transparent); --glass-sunk:color-mix(in srgb,#000 24%,transparent); --hair:color-mix(in srgb,#fff 12%,transparent); --hair-2:color-mix(in srgb,#fff 20%,transparent); }} :root[data-theme="dark"]{ --paper:#0a121a; --surface:#111c26; --surface-2:#16222e; --sunk:#0d1720; --ink:#dde6ef; --ink-2:#9db0c3; --ink-3:#6d8299; --rule:#25374a; --rule-soft:#1c2b38; --blue:#5a9ee0; --on-blue:#08131f; --blue-soft:#13202d; --green:#5dbd90; --green-soft:#12211b; --red:#ff7063; --red-soft:#2a1a1a; --shadow:0 1px 2px rgba(0,0,0,.4),0 14px 36px -20px rgba(0,0,0,.9); --glass:color-mix(in srgb,var(--surface) 58%,transparent); --glass-2:color-mix(in srgb,var(--surface-2) 62%,transparent); --glass-sunk:color-mix(in srgb,#000 24%,transparent); --hair:color-mix(in srgb,#fff 12%,transparent); --hair-2:color-mix(in srgb,#fff 20%,transparent); } /* ---------- the age scale ---------- One hue step per class, terracotta to violet.
