javascript - 带箭头的 slider 导航(HTML、CSS、JAVASCRIPT)

Question

我正在制作这样的 slider 导航:

目前我现在能做到的就是这个

* {
    box-sizing: border-box;
  }
  
  .slider {
    width: 300px;
    text-align: center;
    overflow: hidden;
  }
  
  .slides {
    display: flex;
    
    overflow-x: auto;
    scroll-snap-type: x mandatory;
    
    
    
    scroll-behavior: smooth;
    -webkit-overflow-scrolling: touch;
    
    /*
    scroll-snap-points-x: repeat(300px);
    scroll-snap-type: mandatory;
    */
  }
  .slides::-webkit-scrollbar {
    width: 10px;
    height: 10px;
  }
  .slides::-webkit-scrollbar-thumb {
    background: black;
    border-radius: 10px;
  }
  .slides::-webkit-scrollbar-track {
    background: transparent;
  }
  .slides > div {
    scroll-snap-align: start;
    flex-shrink: 0;
    width: 300px;
    height: 300px;
    margin-right: 50px;
    border-radius: 10px;
    background: #eee;
    transform-origin: center center;
    transform: scale(1);
    transition: transform 0.5s;
    position: relative;
    
    display: flex;
    justify-content: center;
    align-items: center;
    font-size: 100px;
  }
  .slides > div:target {
  /*   transform: scale(0.8); */
  }
  .author-info {
    background: rgba(0, 0, 0, 0.75);
    color: white;
    padding: 0.75rem;
    text-align: center;
    position: absolute;
    bottom: 0;
    left: 0;
    width: 100%;
    margin: 0;
  }
  .author-info a {
    color: white;
  }
  img {
    object-fit: cover;
    position: absolute;
    top: 0;
    left: 0;
    width: 100%;
    height: 100%;
  }
  
  .slider > a {
    display: inline-flex;
    width: 1.5rem;
    height: 1.5rem;
    background: white;
    text-decoration: none;
    align-items: center;
    justify-content: center;
    border-radius: 50%;
    margin: 0 0 0.5rem 0;
    position: relative;
  }
  .slider > a:active {
    top: 1px;
  }
  .slider > a:focus {
    background: #000;
  }
  
  /* Don't need button navigation */
  @supports (scroll-snap-type) {
    .slider > a {
      display: none;
    }
  }
  
  html, body {
    height: 100%;
    overflow: hidden;
  }
  body {
    display: flex;
    align-items: center;
    justify-content: center;
    background: linear-gradient(to bottom, #74ABE2, #5563DE);
    font-family: 'Ropa Sans', sans-serif;
  }

   <div class="slider">
  
    <a href="#slide-1">1</a>
    <a href="#slide-2">2</a>
    <a href="#slide-3">3</a>
    <a href="#slide-4">4</a>
    <a href="#slide-5">5</a>
  
    <div class="slides">
      <div id="slide-1">
        1
      </div>
      <div id="slide-2">
        2
      </div>
      <div id="slide-3">
        3
      </div>
      <div id="slide-4">
        4
      </div>
      <div id="slide-5">
        5
      </div>
    </div>
  </div>

但我需要的正是上图。如何做到这一点？我只是前端的新手，所以基本上我还在从头开始学习 css。

您可以使用jquery并添加一些 CSS

jQuery(document).ready(function($) {

  var slideCount = $('#slider ul li').length;
  var slideWidth = $('#slider ul li').width();
  var slideHeight = $('#slider ul li').height();
  var sliderUlWidth = slideCount * slideWidth;

  $('#slider').css({
    width: slideWidth,
    height: slideHeight
  });

  $('#slider ul').css({
    width: sliderUlWidth,
    marginLeft: -slideWidth
  });

  $('#slider ul li:last-child').prependTo('#slider ul');

  function moveLeft() {
    $('#slider ul').animate({
      left: +slideWidth
    }, 200, function() {
      $('#slider ul li:last-child').prependTo('#slider ul');
      $('#slider ul').css('left', '');
    });
  };

  function moveRight() {
    $('#slider ul').animate({
      left: -slideWidth
    }, 200, function() {
      $('#slider ul li:first-child').appendTo('#slider ul');
      $('#slider ul').css('left', '');
    });
  };

  $('a.control_prev').click(function() {
    moveLeft();
  });

  $('a.control_next').click(function() {
    moveRight();
  });

});
