Auto resize popup box for all screen

Question

I am using Email subscription popup for blogger but that is not resizing screen width wise. How can I modify so that this email subscription popup box automatically set for all screen?

Code is given below:

 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 }
