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%; 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} } </style> </head> <body> <div class="slideshow-container"> <div class="mySlides fade"> <div class="numbertext">1 / 3</div> <img src="img_nature_wide.jpg" style="width:100%"> <div class="text">Caption Text</div> </div> <div class="mySlides fade"> <div class="numbertext">2 / 3</div> <img src="img_snow_wide.jpg" style="width:100%"> <div class="text">Caption Two</div> </div> <div class="mySlides fade"> <div class="numbertext">3 / 3</div> <img src="img_mountains_wide.jpg" style="width:100%"> <div class="text">Caption Three</div> </div> <a class="prev" title="plusSlides(-1)">❮</a> <a class="next" title="plusSlides(1)">❯</a> </div> <br> <div style="text-align:center"> <span class="dot" title="currentSlide(1)"></span> <span class="dot" title="currentSlide(2)"></span> <span class="dot" title="currentSlide(3)"></span> </div> <script> var slideIndex = 1; showSlides(slideIndex); function plusSlides(n) { showSlides(slideIndex += n); } 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"; } </script> </body> </html>
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" title="plusSlides(-1)">❮</a> <a class="next" title="plusSlides(1)">❯</a> </div> <br> <!-- dots/circles --> <div style="text-align:center"> <span class="dot" title="currentSlide(1)"></span> <span class="dot" title="currentSlide(2)"></span> <span class="dot" title="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"; }
