footer stickable to end of the browser window without fixed position

Many web developer always think about why footer is not sticking to end of browser. In this tutorial we will show you to footer stickable to end of browser.

This is scenario:
If content is less than footer need to go bottom of browser and if content is more than footer will go down as per content.

Many people think this is CSS developer’s But I am not think that way. because this is totally different problem.

Some people suggest to use header, middle container and footer height in percentage. But that is wont be possible for all the time.

Here I will give you the solution. Use following JavaScript in document.

<script type="text/javascript">
 var header_height = 150;
 var footer_height = 100;
var reduce_height = header_height+footer_height;
 browserHeight = 0;
 if( typeof( window.innerHeight ) == 'number' ) {
 //Non-IE
 browserHeight = window.innerHeight;
 } else if( document.documentElement &amp;&amp; (  document.documentElement.clientHeight ) ) {
 //IE 6+ in 'standards compliant mode'
 browserHeight = document.documentElement.clientHeight;
 } else if( document.body &amp;&amp; (  document.body.clientHeight ) ) {
 //IE 4 compatible
 browserHeight = document.body.clientHeight;
 }
 // window.alert( 'Height = ' + browserHeight );
 var min_height = browserHeight-reduce_height+ +"px"
 document.write('<style>#middle_container{min-height:'+ min_height +'}</style>');
 //document.getElementById("middle_container").style.minHeight = browserHeight-146+"px";
</script>

Here in this JavaScript I am assuming middle_container is your main block of content. You can change the variables as per your need.
