/* AhoosAI — ahoos-ai.site * * Restrained on purpose. The visual language is type, space and one rule * weight; there are no gradients, no glass, no glow and no cards with shadows. * What carries the page is measure, hierarchy and the amount of nothing * between things. * * Direction is handled with logical properties throughout -- margin-inline, * padding-inline, border-inline, inset-inline. Setting dir="rtl" on * then mirrors the layout for real rather than only moving the text, which is * the difference between a Persian site and an English one with Persian words * in it. */ /* ---- tokens -------------------------------------------------------------- */ :root{ --paper:#fbfaf9; --paper-2:#f4f2f0; --ink:#16150f; --ink-2:#3d3b34; --muted:#75726a; --line:#e2dfda; --line-2:#cdc9c2; --accent:#1b4dd8; --sans-en:"Inter","Segoe UI",-apple-system,BlinkMacSystemFont,Helvetica,Arial,sans-serif; --sans-fa:"Vazirmatn","Segoe UI",Tahoma,Arial,sans-serif; --sans:var(--sans-en); --mono:"Cascadia Mono",Consolas,"SF Mono",Menlo,monospace; --measure:1180px; --gap:clamp(20px,4vw,40px); --header-h:66px; } /* One switch changes the type for the whole document. */ html[lang="fa"]{ --sans:var(--sans-fa); } *,*::before,*::after{box-sizing:border-box} html{-webkit-text-size-adjust:100%;scroll-behavior:smooth;scroll-padding-top:calc(var(--header-h) + 16px)} body{ margin:0;background:var(--paper);color:var(--ink); font-family:var(--sans);font-size:17px;line-height:1.65; font-feature-settings:"kern" 1; -webkit-font-smoothing:antialiased;-moz-osx-font-smoothing:grayscale; } html[lang="fa"] body{line-height:1.9} img{max-width:100%;display:block} a{color:inherit;text-decoration:none} button{font:inherit;color:inherit;background:none;border:0;cursor:pointer} :focus-visible{outline:2px solid var(--accent);outline-offset:3px;border-radius:2px} .wrap{max-width:var(--measure);margin-inline:auto;padding-inline:clamp(20px,5vw,44px)} .skip{position:absolute;inset-inline-start:-9999px;top:0;z-index:200;background:var(--ink); color:var(--paper);padding:12px 18px} .skip:focus{inset-inline-start:0} h1,h2,h3,h4{margin:0;font-weight:600;letter-spacing:-.022em;line-height:1.18} html[lang="fa"] h1,html[lang="fa"] h2,html[lang="fa"] h3,html[lang="fa"] h4{letter-spacing:0;line-height:1.4} p{margin:0} /* ---- header -------------------------------------------------------------- */ .site-header{ position:sticky;top:0;z-index:100;background:rgba(251,250,249,.86); backdrop-filter:saturate(180%) blur(12px); border-block-end:1px solid transparent;transition:border-color .2s ease; } .site-header[data-scrolled="true"]{border-block-end-color:var(--line)} .header-inner{display:flex;align-items:center;gap:18px;height:var(--header-h)} .brand{display:inline-flex;align-items:center;gap:9px; font-size:18px;font-weight:640;letter-spacing:-.03em;white-space:nowrap} /* The mark keeps its own direction: the A does not face the other way in Persian, and the gap beside it is logical so the word still follows. */ .brand .mark{width:26px;height:26px;flex-shrink:0;direction:ltr} .footer-brand .brand .mark{width:22px;height:22px} html[lang="fa"] .brand{letter-spacing:0} .primary-nav{margin-inline-start:auto;display:flex;align-items:center;gap:2px} .primary-nav a{padding:8px 11px;font-size:14.5px;color:var(--ink-2);border-radius:6px; transition:color .15s ease,background-color .15s ease;white-space:nowrap} .primary-nav a:hover{color:var(--ink);background:var(--paper-2)} .header-tools{display:flex;align-items:center;gap:10px;margin-inline-start:14px} .lang{display:flex;border:1px solid var(--line-2);border-radius:7px;overflow:hidden} .lang button{padding:5px 10px;font-size:12.5px;font-weight:560;color:var(--muted); letter-spacing:.03em;transition:.15s} .lang button[aria-pressed="true"]{background:var(--ink);color:var(--paper)} .lang button:not([aria-pressed="true"]):hover{background:var(--paper-2);color:var(--ink)} .tg{width:34px;height:34px;border:1px solid var(--line-2);border-radius:7px; display:grid;place-items:center;color:var(--ink-2);transition:.15s} .tg:hover{border-color:var(--ink);color:var(--ink)} .menu-btn{display:none;width:36px;height:36px;place-items:center} /* ---- hero ---------------------------------------------------------------- */ /* Tall on purpose: the assembly is tied to how far this section has been scrolled, so it needs room to happen in. */ .hero{position:relative;height:300vh} .hero-sticky{position:sticky;top:0;height:100vh;display:grid;place-items:center;overflow:hidden} .hero-inner{position:relative;width:min(760px,86vw);text-align:center} .hero-stage{position:relative;width:min(420px,72vw);aspect-ratio:1;margin-inline:auto} /* The wordmark and the assembled mark occupy the same square.
