javascript - 调整浏览器大小时html页面变得疯狂

所以我想建立一个包含3个页面和一个进度条的模式，每当我点击一个按钮时，它就会改变。问题是当我调整浏览器的大小时，进度条会从模式中消失。
这是我的代码：

$( document ).ready(function() {
  $('.trigger').click(function() {
     $('.modal-wrapper').toggleClass('open');
    $('.page-wrapper').toggleClass('blur');
     return false;
  });
  $('.go').click(function () {
           $('.pg2').toggleClass('active') ;
  }) ;
  $('.gg').click(function () {
           $('.pg3').toggleClass('active') ;
  }) ;
});

var pageIndex = 1;
showPages(pageIndex);

function nextPage(n) {
  showPages(pageIndex += n);
}

function showPages(n) {
  var i;
  var pages = document.getElementsByClassName("pop");
  if (n > pages.length) {pageIndex = 1}
  if (n < 1) {pageIndex = pages.length}
  for (i = 0; i < pages.length; i++) {
      pages[i].style.display = "none";
  }

  pages[pageIndex-1].style.display = "block";

}

最佳答案

我想你的问题是：

  .progressbar li {
      list-style-type: none;
      width: 15%;
      float: left;
      font-size: 12px;
      position: relative;
      text-align: center;
      text-transform: uppercase;
      color: #7d7d7d;
      left:350px;
      height: 10px;
  }

left:350px;属性正在硬编码一个将进度条推到右边的值。。。我建议使用百分比。创建进度条的列表也在模式视图之外。最好是在里面。
最后，如果您正在测试响应式设计，请在您的<meta name="viewport" content="width=device-width, initial-scale=1">中添加此元标记head。当它在移动设备上呈现时，它将帮助您的站点
