javascript - 自动调整所有屏幕的弹出框

Question

我正在为博主使用电子邮件订阅弹出窗口，但这并没有明智地调整屏幕宽度。我该如何修改，以便自动为所有屏幕设置此电子邮件订阅弹出框？

代码如下:

jQuery(document).ready(function($) {
  if ($.cookie('popup-email-box') != 'yes') {
    $('.outer-email-popup-box').delay(10000).fadeIn('medium');
    $('.exit-button-subbox, .button').click(function() {
      $('.outer-email-popup-box').stop().fadeOut('medium');
    });
  }
  $.cookie('popup-email-box', 'yes', {
    path: '/',
    expires: 5
  });
});

.outer-email-popup-box {
  display: none;
  background: rgba(0, 0, 0, 0.8);
  width: 100%;
  height: 100%;
  position: fixed;
  top: 0;
  left: 0;
  z-index: 99999;
}

.email-popup-box {
  width: 500px;
  height: 280px;
  position: fixed;
  top: 0;
  left: 0;
  right: 0;
  bottom: 25%;
  margin: auto;
  text-align: center;
  background: #fff;
  -webkit-animation: swinging 10s ease-in-out 0s infinite;
  -moz-animation: swinging 10s ease-in-out 0s infinite;
  animation: swinging 10s ease-in-out 0s infinite;
}

.email-popup-header {
  text-align: center;
  font-size: 2em;
  color: #FFFFFF;
  background: #006D90;
  padding: 4px 15px 7px 10px;
  margin: 13px 0px 14px 0px;
}

.email-popup-subheader {
  text-align: center;
  font-size: 1.1em;
  color: #676767;
  padding: 0px 0px 2px
}

.email-popup-body {
  text-align: center;
  margin-top: 9px;
  padding: 22px 0px 3px 0px;
  background: #006D90;
}

.email-right {
  background: green;
  float: right;
}

.email-left {
  background: red;
  float: left;
}

.email-form {
  width: 80%;
  margin: 0 auto;
}

.in-popup-mail {
  padding: 10px;
  margin: 0 auto;
  width: 270px
}

.btn-popup-mail {
  padding: 10px;
  background: #006D90;
  border: 2px solid #fff;
  color: #fff;
  margin: 0 auto;
}

.btn-popup-mail:hover {
  background: #003E52
}

.background-img {
  width: 40px;
  margin: 0 auto;
  padding-top: 5px
}

.exit-button-subbox {
  float: right;
  cursor: pointer;
  position: absolute;
  right: 0px;
  top: 0px;
  margin-top: 4px;
  margin-right: 4px;
}

.exit-button-subbox:before {
  content: "X";
  padding: 4px 4px;
  background: #FFFFFF;
  color: #000000;
  font-weight: normal;
  font-size: 15px;
  font-family: sans-serif;
}

.footer-popup-mail {
  color: #fff;
  font-size: 12px;
  margin-top: -5px
}

.footer-popup-mail a {
  color: #fff
}
