CSS - Center Footer Content

I need to center my footers content and I can not make it works.

I am centering my page using: #wrap {width: 960px;margin: 0 auto;}

I have used float:left; float:right; in my header and content.

So, I try to center my footers content making use of:

#footer {height:0 auto;min-width:960px;float:left;}

div.inner_footer {heigh开发者_开发百科t:720px;width:960px;margin:0 auto;}

The whole footer goes to the left and shows only half footer in the main page.

Then, I take off float:left; from #footer {height:0 auto;min-width:960px;float:left;} the footer goes straight to the top.

Thank you.

Try adding clear: both to your footer, and removing float: left
