Slideshow / Carousel

Slideshow digunakan untuk menelusuri elemen.

Contoh:

<!DOCTYPE html>
<html>
<head>
<meta name="viewport" content="width=device-width, initial-scale=1">
<style>
* {box-sizing: border-box}
body {font-family: Verdana, sans-serif; margin:0}
.mySlides {display: none}
img {vertical-align: middle;}

/* Kontainer Slideshow */
.slideshow-container {
  max-width: 1000px;
  position: relative;
  margin: auto;
}

/* tombol Next & previous */
.prev, .next {
  cursor: pointer;
  position: absolute;
  top: 50%;
  width: auto;
  padding: 16px;
  margin-top: -22px;
  color: white;
  font-weight: bold;
  font-size: 18px;
  transition: 0.6s ease;
  border-radius: 0 3px 3px 0;
  user-select: none;
}

/* Posisikan "next button" di sebelah kanan */
.next {
  right: 0;
  border-radius: 3px 0 0 3px;
}

/* Saat mengarahkan kursor, tambahkan warna background hitam dengan sedikit tembus pandang */
.prev:hover, .next:hover {
  background-color: rgba(0,0,0,0.8);
}

/* teks Caption */
.text {
  color: #f2f2f2;
  font-size: 15px;
  padding: 8px 12px;
  position: absolute;
  bottom: 8px;
  width: 100%;

/* Teks angka (1/3 dll) */
.numbertext {
  color: #f2f2f2;
  font-size: 12px;
  padding: 8px 12px;
  position: absolute;
  top: 0;
}

/* Titik / bullet / indikator */
.dot {
  cursor: pointer;
  height: 15px;
  width: 15px;
  margin: 0 2px;
  background-color: #bbb;
  border-radius: 50%;
  display: inline-block;
  transition: background-color 0.6s ease;
}

.active, .dot:hover {
  background-color: #717171;
}

/* Animasi memudar */
.fade {
  -webkit-animation-name: fade;
  -webkit-animation-duration: 1.5s;
  animation-name: fade;
  animation-duration: 1.5s;
}

@-webkit-keyframes fade {

}

@keyframes fade {
  from {opacity: .4} 
  to {opacity: 1}
}

/* Pada layar yang lebih kecil, kurangi ukuran teks */
@media only screen and (max-width: 300px) {
  .prev, .next,.text {font-size: 11px}
}
</style>
</head>
<body>

<div class="mySlides fade">
  <div class="numbertext">2 / 3</div>
  <img src="img_snow_wide.jpg" style="width:100%">

Buat Slideshow

Langkah 1) Tambahkan HTML

Contoh:

<!-- Kontainer Slideshow -->
<div class="slideshow-container">

  <!-- Full-width images with number and caption text -->
  <div class="mySlides fade">
    <div class="numbertext">1 / 3</div>
    <img src="img1.jpg" style="width:100%">
    <div class="text">Caption Text</div>
  </div>

  <div class="mySlides fade">
    <div class="numbertext">2 / 3</div>
    <img src="img2.jpg" style="width:100%">
    <div class="text">Caption Two</div>
  </div>

  <div class="mySlides fade">
    <div class="numbertext">3 / 3</div>
    <img src="img3.jpg" style="width:100%">
    <div class="text">Caption Three</div>
  </div>

  <!-- Tombol Next dan previous -->
  <a class="prev" onclick="plusSlides(-1)">❮</a>
  <a class="next" onclick="plusSlides(1)">❯</a>
</div>
<br>

<!-- dots/circles -->
<div style="text-align:center">
  <span class="dot" onclick="currentSlide(1)"></span>
  <span class="dot" onclick="currentSlide(2)"></span>
  <span class="dot" onclick="currentSlide(3)"></span>
</div>

Langkah 2) Tambahkan CSS

Style pada tombol next dan previous , teks keterangan dan titik:

Contoh:

* {box-sizing:border-box}

/* Kontainer Slideshow */
.slideshow-container {
  max-width: 1000px;
  position: relative;
  margin: auto;
}

/* tombol Next & previous */
.prev, .next {
  cursor: pointer;
  position: absolute;
  top: 50%;
  width: auto;
  padding: 16px;
  margin-top: -22px;
  color: white;
  font-weight: bold;
  font-size: 18px;
  transition: 0.6s ease;
  border-radius: 0 3px 3px 0;
  user-select: none;
}

/* Posisikan "next button" di sebelah kanan */
.next {
  right: 0;
  border-radius: 3px 0 0 3px;
}

/* Saat mengarahkan kursor, tambahkan warna background hitam dengan sedikit tembus pandang */
.prev:hover, .next:hover {
  background-color: rgba(0,0,0,0.8);
}

/* teks Caption */
.text {
  color: #f2f2f2;
  font-size: 15px;
  padding: 8px 12px;
  position: absolute;
  bottom: 8px;
  width: 100%;
  text-align: center;
}

/* Teks angka (1/3 dll) */
.numbertext {
  color: #f2f2f2;
  font-size: 12px;
  padding: 8px 12px;
  position: absolute;
  top: 0;
}

/* Titik / bullet / indikator */
.dot {
  cursor: pointer;
  height: 15px;
  width: 15px;
  margin: 0 2px;
  background-color: #bbb;
  border-radius: 50%;
  display: inline-block;
  transition: background-color 0.6s ease;
}

.active, .dot:hover {
  background-color: #717171;
}

/* Animasi memudar */
.fade {
  -webkit-animation-name: fade;
  -webkit-animation-duration: 1.5s;
  animation-name: fade;
  animation-duration: 1.5s;
}

@-webkit-keyframes fade {
  from {opacity: .4} 
  to {opacity: 1}
}

@keyframes fade {
  from {opacity: .4} 
  to {opacity: 1}
}

/* Pada layar yang lebih kecil, kurangi ukuran teks */
@media only screen and (max-width: 300px) {
  .prev, .next,.text {font-size: 11px}
}

Langkah 3) Tambahkan JavaScript

Contoh:

var slideIndex = 1;
showSlides(slideIndex);

// Next/previous controls
function plusSlides(n) {
  showSlides(slideIndex += n);
}

// Thumbnail image controls
function currentSlide(n) {
  showSlides(slideIndex = n);
}

function showSlides(n) {
  var i;
  var slides = document.getElementsByClassName("mySlides");
  var dots = document.getElementsByClassName("dot");
  if (n > slides.length) {slideIndex = 1}
  if (n < 1) {slideIndex = slides.length}
  for (i = 0; i < slides.length; i++) {
      slides[i].style.display = "none";
  }
  for (i = 0; i < dots.length; i++) {
      dots[i].className = dots[i].className.replace(" active", "");
  }
  slides[slideIndex-1].style.display = "block";
  dots[slideIndex-1].className += " active";
}

Slideshow Otomatis

Untuk menampilkan slideshow otomatis, gunakan kode berikut.

Contoh:

var slideIndex = 0;
showSlides();

function showSlides() {
  var i;
  var slides = document.getElementsByClassName("mySlides");
  for (i = 0; i < slides.length; i++) {
    slides[i].style.display = "none";
  }
  slideIndex++;
  if (slideIndex > slides.length) {slideIndex = 1}
  slides[slideIndex-1].style.display = "block";
  setTimeout(showSlides, 2000); // Ubah gambar setiap 2 detik
}

Multiple Slideshow

Contoh:

var slideIndex = [1,1];
/* Masukkan anggota setiap grup slideshow dengan kelas CSS yang berbeda */
var slideId = ["mySlides1", "mySlides2"]
showSlides(1, 0);
showSlides(1, 1);

function plusSlides(n, no) {
  showSlides(slideIndex[no] += n, no);
}

function showSlides(n, no) {
  var i;
  var x = document.getElementsByClassName(slideId[no]);
  if (n > x.length) {slideIndex[no] = 1}
  if (n < 1) {slideIndex[no] = x.length}
  for (i = 0; i < x.length; i++) {
    x[i].style.display = "none";
  }
  x[slideIndex[no]-1].style.display = "block";
}
