html - How to maintain the size of webpage to be same in every browser/full screen? -


i've written html , looks nice in google chrome when on firefox, has white space @ bottom. when go full screen, has white space @ bottom.

how can solve problem? thanks.

my code:

.mainwrapper {     margin-left: auto;     margin-right: auto;     background-image: url(../img/homebg.png);     background-repeat: no-repeat;     background-attachment: fixed;     -webkit-background-size: cover;     -moz-background-size: 100% 100%, auto;     -o-background-size: 100% 100%, auto;     background-size: 100% 100%, auto;     height: 100%;     margin-top: 0px;     margin-bottom: 0px; }   body {     margin: 0;     padding: 0;     font-family: kaiti, "arial unicode ms";     font-size: 100%;     color: #000; } 

sometimes helps put height of html , body @ 100%. padding: 0 , margin: 0 should in html , body styles ensure there no unwanted borders.

.mainwrapper {     background: url(bg.png) no-repeat center center fixed;      -webkit-background-size: cover;     -moz-background-size: cover;     -o-background-size: cover;     background-size: cover;     height: 100%; }  body {     margin: 0;     padding: 0;     height: 100%;     font-family: kaiti, "arial unicode ms";     font-size: 100%;     color: #000; }  html {     height: 100%;     padding: 0;     margin: 0; } 

i think don't understand concept of div. if want fullscreen background should apply background image body style this:

body {     background: url(bg.png) no-repeat center center fixed;     background-size: cover;     height: 100%;      } 

you should use div big screen fill background image. thats why have body. , image move while scrolling , have no white borders @ all.

if still want use div used parts of website not substitute body have deal fact won't move while scrolling (except have script it).
