Jquery, Change Div Height To Automatically Fill Out Remainder Of Screen If Content Isn't Already Larger

My site is structured roughly like this: ----------------- header ----------------- | | side| main | | -----------------

Solution 1:

The method is called sticky footer, and you don't need jQuery for that. You can use CSS:

[See it in action]

/* 
Sticky Footer by Ryan Fait
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 */
}
