Dizajn Systém & CSS

HTML dáva webu význam, ale CSS mu dáva dušu. V tomto projekte nepoužívame žiadne frameworky (ako Bootstrap alebo Tailwind). Píšeme Custom CSS pre maximálnu kontrolu nad vizuálom a výkonom.

Nižšie analyzujeme kľúčové techniky použité pri tvorbe portfólia: od Bento Grid layoutu až po pokročilý Glassmorphism efekt.

1. Globálny Reset a Debugging

Každý dobrý CSS súbor začína resetom. Prehliadače majú rôzne predvolené nastavenia, ktoré chceme zjednotiť.

* {
    margin: 0;
    padding: 0;
    box-sizing: border-box;
    border: red solid 0.3px; /* Debugging trik: vidíme hranice elementov */
}
Box-Sizing: Border-Box

Najdôležitejší riadok v CSS. Zabezpečuje, že padding a border nezväčšujú element nad rámec definovanej šírky. Bez tohto sa layouty ťažko počítajú.

Červený Border (Debug)

Trik pokročilých vývojárov. Pridanie tenkého červeného okraja na * nám umožní okamžite vidieť, ako sú elementy poskladané a kde nám preteká obsah.

2. Bento Grid Layout

Srdcom dizajnu je "Bento Grid" – modulárna mriežka inšpirovaná japonskými boxmi na obed. Používame CSS Grid s 12 stĺpcami pre maximálnu flexibilitu.

.bento-grid {
    display: grid;
    grid-template-columns: repeat(12, 1fr); /* 12 flexibilných stĺpcov */
    gap: 1.5rem;
    margin-bottom: 1.5rem;
}

#hero {
    grid-column: span 6; /* Zaberá polovicu (6/12) */
    min-height: 500px;
}

article {
    grid-column: span 4; /* Zaberá tretinu (4/12) */
}

3. Glassmorphism (Efekt Skla)

Pre tlačidlá sme použili moderný "frosted glass" efekt. Toto je najkomplexnejšia časť CSS, ktorá využíva vrstvenie tieňov, priehľadnosti a filtrov.

.glass-button {
    background: linear-gradient(-75deg, rgba(255,255,255,0.08), rgba(255,255,255,0.08));
    backdrop-filter: blur(4px); /* Rozmaže pozadie za tlačidlom */
    border-radius: 999vw;     /* Dokonalá pilulka */
    box-shadow: 
        inset 0 0.125em 0.125em rgba(255, 255, 255, 0.1), /* Vnútorný odlesk */
        0 0.25em 0.125em -0.125em rgba(0, 0, 0, 0.5);     /* Vonkajší tieň */
}

4. Kompletný CSS Kód

Tu je kompletný stylesheet pre portfólio. Skopírujte tento kód do súboru style/finalPage/style.css.
