javascript - 使控件位于我的幻灯片中并始终停留在同一位置

Question

我的幻灯片控件一直存在问题，我无法将幻灯片控件/导航卡在幻灯片底部，但在幻灯片内部，无论窗口大小如何，控件都应始终位于同一位置。

此刻您将如何看待图像外部的控件，如果我调整窗口大小时它们将改变位置。

var seconds = 2; //time beetwen auto slide
var delay = 8; //time to restart auto slide

var slider = $('#slider');
var images = $('#slider .images');
var controls = $('<div>').addClass('controls');
slider.after(controls);
var width = images.width();
var slideClick = function () {  
  var b = $(this);
  $('.controls div').removeClass('current');
  b.addClass('current');
  var index = b.index();
  images.css('left', -1 * index * width);
};
$('#slider .images img').each(function (i) {
  var img = $(this);
  img.css('left', i * width);
  var button = $('<div>');
  controls.append(button);
  if (i == 0) { button.addClass('current') }
  button.click(function(){
    clearInterval(autoSlideInterval);
    slideClick.apply(this);
    setTimeout(function () {
       setInterval(autoSlide, seconds * 1000);     
    }, delay * 1000);
  });
});
var autoSlide = function(){
  var next = $('.controls .current').next();
  if (next.length) {
    slideClick.apply(next); 
  } else {
    var first = $('.controls div').first();
    slideClick.apply(first); 
  }
};
var autoSlideInterval = setInterval(autoSlide, seconds * 1000);

幻灯片的css是“slider”和“controls”。

TL:DR:我怎样才能让幻灯片的控件在其中，关闭底部并且在我们调整窗口大小时不改变位置。

编辑

HTML:

<div id="slider">
    <div class="controls">
      <img src="img/3.png" alt="Image-1" />
      <img src="img/2.png" alt="Image-2" />
      <img src="img/1.png" alt="Image-3" />
      <img src="img/4.png" alt="Image-4" />
    </div> 
    <div class="controls"></div>
  </div>

CSS:

    #slider {
  width: 100%;
    height: 100%;
    overflow: hidden;
    position: relative;
}

#slider .images .controls  { 
  width: 100%;
  height: 658px;
  position: relative;
  transition: left 1s;
  left: 0;
}

#slider .images img {
  z-index: -1;
  width: 100%;
  background-size: 100%;
  position: absolute;
}

.controls {
  width: 100%;
    display: flex;
    position: absolute;
    justify-content: center;
    top: 80%;
}

.controls div {

  width: 16px;
  height: 16px;
  margin: 0 5px;
  background: tomato;
  border-radius: 50%;
}

.controls .current {
  background: red;
}

Answer 1

在#slider .images .controls 中重命名控件类。
将您的圈子 parent -> (controls) 移动到 #slider 。

设置这个CSS代码

.controls {
    width: 100%;
    display: flex;
    position: absolute;
    justify-content: center;
    top: 80%;
}
#slider {
    width: 100%;
    height: 100%;
    overflow: hidden;
    position: relative;
}

为#slider 编辑此代码。image 将高度设置为图像的高度。

height : Your Image's height;

并删除Body中的这段CSS代码

min-width:900px;
