/* ========================================================================== MMS E-Portfolio — Component + Layout Styles Design TOKENS (colors, fonts, spacing) live in css/theme.css, not here — this file only consumes var(--...) tokens, it never hardcodes a color. theme.css must be linked before this file in every page's . RESPONSIVE BREAKPOINTS IN THIS FILE (search these markers to jump there): - 767px and below → "RESPONSIVE: MOBILE (<=767px)" section, near the end of this file. Collapses the nav to a hamburger menu and stacks a few layout blocks. - 768px–1023px → "RESPONSIVE: TABLET" section, right after it. Spacing-only tweaks, no nav logic. - Nav's DESKTOP DEFAULT (>=768px) is not a media query — it's simply the unguarded base rules under "Header / Nav" below. Anything that changes how the nav looks/behaves on desktop lives THERE, and anything for mobile lives in the MOBILE media query — never both in the same place, so a search for one won't land you in the other. GUARD RAIL: if your edit is only about color/theme values, you should never need to touch anything between the "RESPONSIVE:" markers, and you should never need to touch this file at all — theme.css is enough. If a change you're making WOULD affect nav layout/breakpoints, flag it before editing rather than doing it inline with an unrelated change. ========================================================================== */ /* ========================================================================== Reset & base ========================================================================== */ *, *::before, *::after { box-sizing: border-box; } html { scroll-behavior: smooth; -webkit-text-size-adjust: 100%; } @media (prefers-reduced-motion: reduce) { html { scroll-behavior: auto; } *, *::before, *::after { animation-duration: 0.01ms !important; animation-iteration-count: 1 !important; transition-duration: 0.01ms !important; scroll-behavior: auto !important; } } body { margin: 0; background: var(--color-background); color: var(--color-foreground); font-family: var(--font-body); font-size: var(--text-base); line-height: var(--leading-body); -webkit-font-smoothing: antialiased; } img { max-width: 100%; display: block; } h1, h2, h3, h4 { font-family: var(--font-heading); font-weight: 600; line-height: 1.15; margin: 0 0 var(--space-4); color: var(--color-foreground); } p { margin: 0 0 var(--space-4); } p:last-child { margin-bottom: 0; } a { color: var(--color-primary); text-decoration-thickness: 1px; text-underline-offset: 3px; } a:hover { color: var(--color-primary-hover); } ul { margin: 0; padding: 0; list-style: none; } button { font: inherit; color: inherit; background: none; border: none; cursor: pointer; } /* Visible focus ring everywhere — never remove */ :focus-visible { outline: 2px solid var(--color-ring); outline-offset: 3px; } .wrap { max-width: var(--content-max); margin-inline: auto; padding-inline: var(--space-6); } .eyebrow { font-family: var(--font-body); font-size: 0.8125rem; font-weight: 700; letter-spacing: 0.08em; text-transform: uppercase; color: var(--color-primary-hover); margin: 0 0 var(--space-2); } .skip-link { position: absolute; left: -9999px; top: 0; background: var(--color-primary); color: var(--color-on-primary); padding: var(--space-3) var(--space-6); z-index: 100; border-radius: 0 0 var(--radius) 0; } .skip-link:focus { left: 0; } /* ========================================================================== Buttons ========================================================================== */ .btn { display: inline-flex; align-items: center; justify-content: center; min-height: 44px; padding: var(--space-3) var(--space-6); border-radius: var(--radius); font-weight: 700; font-size: 0.9375rem; text-decoration: none; border: var(--border-w) solid transparent; transition: background-color var(--duration) var(--ease), color var(--duration) var(--ease), border-color var(--duration) var(--ease); } .btn-primary { background: var(--color-primary); color: var(--color-on-primary); } .btn-primary:hover { background: var(--color-primary-hover); color: var(--color-on-primary); } .btn-ghost { border-color: var(--color-foreground); color: var(--color-foreground); } .btn-ghost:hover { background: var(--color-foreground); color: var(--color-background); } /* ========================================================================== Header / Nav ⚠ NAV LAYOUT — this block + its mobile counterpart in the "RESPONSIVE: MOBILE (<=767px)" section near the end of this file are the ONLY two places nav layout/breakpoint logic lives.
