我做错什么了?我想把表单(ţmsform,ţmsform fieldset)放在所有浏览器的中心,我想把图像保持在边框表单,拉伸表单,不要超出右边框。。。
JSFiddle

#msform {
    width: 1200px;
    margin: 50px auto;
    text-align: center;
    position: relative;
}
#msform fieldset {
    background: white;
    border: 0 none;
    border-radius: 3px;
    box-shadow: 0 0 15px 1px rgba(0, 0, 0, 0.4);
    padding: 20px 30px;

    box-sizing: border-box;
    width: 80%;
    margin: 0 10%;

    /*stacking fieldsets above each other*/
    position: absolute;
}

请帮忙。。

#msform的宽度更改为100%左右,对于img
将您的代码片段复制到此处:

//jQuery time
var current_fs, next_fs, previous_fs; //fieldsets
var left, opacity, scale; //fieldset properties which we will animate
var animating; //flag to prevent quick multi-click glitches

$(".next").click(function() {
  if (animating) return false;
  animating = true;
  current_fs = $(this).parent();
  if ($(this).attr('name') == 'feveryes')
    next_fs = $('#feveryes');
  if ($(this).attr('name') == 'feverno')
    next_fs = $('#feverno');
  if ($(this).attr('name') == 'coughyes')
    next_fs = $('#coughyes');
  if ($(this).attr('name') == 'coughno')
    next_fs = $('#coughno');
  if ($(this).attr('name') == 'previous')
    next_fs = $('#firstField');

  //activate next step on progressbar using the index of next_fs
  $("#progressbar li").eq($("fieldset").index(next_fs)).addClass("active");

  //show the next fieldset
  next_fs.show();
  //hide the current fieldset with style
  current_fs.animate({
    opacity: 0
  }, {
    step: function(now, mx) {
      //as the opacity of current_fs reduces to 0 - stored in "now"
      //1. scale current_fs down to 80%
      scale = 1 - (1 - now) * 0.2;
      //2. bring next_fs from the right(50%)
      left = (now * 50) + "%";
      //3. increase opacity of next_fs to 1 as it moves in
      opacity = 1 - now;
      //current_fs.css({'transform': 'scale('+scale+')'});
      next_fs.css({
        'left': left,
        'opacity': opacity
      });
    },
    duration: 800,
    complete: function() {
      current_fs.hide();
      animating = false;
    },
    //this comes from the custom easing plugin
    easing: 'easeInOutBack'
  });
});

$(".previous").click(function() {
  if (animating) return false;
  animating = true;

  current_fs = $(this).parent();
  previous_fs = $('#firstField');

  //de-activate current step on progressbar
  $("#progressbar li").eq($("fieldset").index(current_fs)).removeClass("active");

  //show the previous fieldset
  previous_fs.show();
  //hide the current fieldset with style
  current_fs.animate({
    opacity: 0
  }, {
    step: function(now, mx) {
      //as the opacity of current_fs reduces to 0 - stored in "now"
      //1. scale previous_fs from 80% to 100%
      scale = 0.8 + (1 - now) * 0.2;
      //2. take current_fs to the right(50%) - from 0%
      left = ((1 - now) * 50) + "%";
      //3. increase opacity of previous_fs to 1 as it moves in
      opacity = 1 - now;
      current_fs.css({
        'left': left
      });
      previous_fs.css({
        'transform': 'scale(' + scale + ')',
        'opacity': opacity
      });
    },
    duration: 800,
    complete: function() {
      current_fs.hide();
      animating = false;
    },
    //this comes from the custom easing plugin
    easing: 'easeInOutBack'
  });

$(".submit").click(function() {
