Introduction of slick

Describe the following in the head and in the html file where you want to implement the slide show.


  <link rel="stylesheet" type="text/css" href="//cdn.jsdelivr.net/npm/[email protected]/slick/slick.css"/>
  <link rel="stylesheet" type="text/css" href="//cdn.jsdelivr.net/npm/[email protected]/slick/slick-theme.css"/>
<script type="text/javascript" src="//cdn.jsdelivr.net/npm/[email protected]/slick/slick.min.js"></script>

Description to application

HTML Describe the following in the html file you want to implement the slide show

<div id="slider">
  <% @posts.each do |post| %>
    <%= attachment_image_tag post, :image, :fill, 1200, 800, format: "jpeg" %>
   <% end %>



$(function() {
      dots: true, //Show dot navigation below slides
      autoplay: true, //auto play
      autoplaySpeed: 4000, //Playback speed

css Adjust the position of the next and front buttons after the slide


.slick-next {
	right: 10px !important;
	z-index: 100;

.slick-prev {
	left: 10px !important;
  z-index: 100;

That's all there is to it.

スライドショー2.gif If you want to make multiple slides like the one above, change the js description a bit.



$(function() {
      autoplay: true,
      autoplaySpeed: 4000,
      slidesToShow: 3, //Number of slides to display
      slidesToScroll: 3, //Number of slides switched by scrolling

      //If you want to make it responsive, also describe the following
      responsive: [{
        breakpoint: 768, //The following settings with a screen width of 768px
        settings: {
          slidesToShow: 2,
          slidesToScroll: 2,
