Vous devez utiliser un collant pied de solution comme celle-ci : http://ryanfait.com/sticky-footer/
* {
margin: 0;
}
html, body {
height: 100%;
}
.wrapper {
min-height: 100%;
height: auto !important;
height: 100%;
margin: 0 auto -142px; /* the bottom margin is the negative value of the footer's height */
}
.footer, .push {
height: 142px; /* .push must be the same height as .footer */
}
Il existe d'autres comme http://www.cssstickyfooter.com/
* {margin:0;padding:0;}
/* must declare 0 margins on everything, also for main layout components use padding, not
vertical margins (top and bottom) to add spacing, else those margins get added to total height
and your footer gets pushed down a bit more, creating vertical scroll bars in the browser */
html, body, #wrap {height: 100%;}
body > #wrap {height: auto; min-height: 100%;}
#main {padding-bottom: 150px;} /* must be same height as the footer */
#footer {position: relative;
margin-top: -150px; /* negative value of footer height */
height: 150px;
clear:both;}
/* CLEAR FIX*/
.clearfix:after {content: ".";
display: block;
height: 0;
clear: both;
visibility: hidden;}
.clearfix {display: inline-block;}
/* Hides from IE-mac \*/
* html .clearfix { height: 1%;}
.clearfix {display: block;}
avec le code html:
<div id="wrap">
<div id="main" class="clearfix">
</div>
</div>
<div id="footer">
</div>
