Kartice in fotogalerija

Pokazal ti bom: kartica

Kartica je bel pravokotnik s senco, ki drži skupaj sliko in besedilo. Poznaš jih z YouTuba, Netflixa in spletnih trgovin. Kartica je samo škatla z nekaj lastnostmi:

<div class="card">
  <img src="images/photo.jpg" alt="Photo description">
  <h3>Card heading</h3>
  <p>Short text for the card.</p>
</div>

.card {
  background-color: white;
  border-radius: 12px;
  padding: 16px;
  box-shadow: 0 4px 12px rgba(0, 0, 0, 0.1);
}

Tu sta dve novosti:

• <div> je prazna škatla brez lastnega pomena – samo »paket« za stvari, ki spadajo skupaj.
• box-shadow je senca: številke pomenijo premik desno, premik dol, zameglitev in barvo (tukaj črna pri 10 % prosojnosti). Senca je tisto, kar iz ploščatega pravokotnika naredi kartico.

Pokazal ti bom: kartice druga ob drugi

Zdaj trik, ki ga že poznaš – flexbox. Kartice zavij v škatlo in ji nastavi flex:

<div class="cards">
  <div class="card">…</div>
  <div class="card">…</div>
  <div class="card">…</div>
</div>

.cards {
  display: flex;
  gap: 16px;
  flex-wrap: wrap;
}

.cards .card {
  flex: 1;             /* cards fairly share the available space */
  min-width: 200px;    /* but none will ever be narrower than 200px */
}

flex-wrap: wrap + min-width = na računalniku kartice stojijo druga ob drugi, na telefonu se zložijo. Pravkar si zgradil odzivno spletno stran – tako, ki se prilagodi vsakemu zaslonu.

Na tebi je 💪

Na spletno stran dodaj razdelek s karticami – vsaj tri druga ob drugi. Kaj je na njih, je odvisno od tvojega projekta:

  </div>
  <div class="card">

  </div>
</div>

Isti CSS deluje za vsak projekt:

.cards {
  display: flex;
  gap: 16px;
  flex-wrap: wrap;
}

.cards .card {
  flex: 1;
  min-width: 200px;
}

.card {
  background-color: white;
  border-radius: 12px;
  padding: 16px;
  box-shadow: 0 4px 12px rgba(0, 0, 0, 0.1);
}

Bonus: fotogalerija

Imaš veliko fotografij? Mreža fotografij je še preprostejša – uporabi aspect-ratio in object-fit, da so vse enake velikosti:

<div class="gallery">
  <img src="images/p1.jpg" alt="…">
  <img src="images/p2.jpg" alt="…">
  <img src="images/p3.jpg" alt="…">
  <img src="images/p4.jpg" alt="…">
</div>

.gallery {
  display: flex;
  gap: 8px;
  flex-wrap: wrap;
}

.gallery img {
  width: 180px;
  aspect-ratio: 1;      /* a square */
  object-fit: cover;    /* the photo fills the square and gets cropped, not squished */
}

Kaj odneseš iz lekcije

• <div> je ovijalna škatla za stvari, ki spadajo skupaj.
• Kartica = ozadje + border-radius + padding + box-shadow.
• Flexbox z flex-wrap in min-width = postavitev, ki deluje na računalniku in telefonu.
