Help Much Appreciated - Expand wrapper entire height

Hey guys. I am currently working on a website for a client and I have run into an issue I cannot seem to fix.
The issue is that on the website, when there isnt enough content to push the wrapper down to the footer, i want the wrapper to automatically push down to the footer... no matter what i do in the css it will not work..

you can view the error on this page:

Thanks for the help guys,

 

you can give specific height or do auto height content-block div class..... then it will automatically expand when data inserted in it

 

yes, but height:100%, which is what i want, does not work.

 

try to remove your footer in the wrapper and make your wrapper in height 100% and min-height 100% and make your footer have a height also and margin minus it in the height of your footer.

example:

 

That didnt work, sorry. but thanks for trying

 

Doesent really work. Google "stick footer to the bottom" there are a few tricks but i wouldnt recomend using em.
