CSS: fixed to bottom and centered

I need my footer to be fixed to the bottom of the page and to center it. The contents of the footer may change at all time so I can't just center it via margin-left: xxpx; margin-right: xxpx;

The problem is that for some reason this doesn't work:

#whatever {
  position: fixed;
  bottom: 0px;
  margin-right: auto;
  margin-left: auto;
}

I crawled the web and found nothing. I tried making a container div and nada. I tried other combinations and gurnisht. How can I make this happen?

Thanks

You should use a sticky footer solution such as this one : 

* {
    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 */
}

There are others like this;

* {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;}

with the html:

<div id="wrap">

    <div id="main" class="clearfix">

    </div>

</div>

<div id="footer">

</div>

I ran into a problem where the typical position: fixed and bottom: 0 didn't work. Discovered a neat functionality with position: sticky. Note it's "relatively" new so it won't with IE/Edge 15 and earlier.

Here's an example for w3schools.

<!DOCTYPE html>
<html>
<head>
<style>
div.sticky {
  position: sticky;
  bottom: 0;
  background-color: yellow;
  padding: 30px;
  font-size: 20px;
}
</style>
</head>
<body>

There are 2 potential issues that I see:

1 - IE has had trouble with position:fixed in the past. If you are using IE7+ with a valid doctype or a non-IE browser this isn't part of the problem

2 - You need to specify a width for the footer if you want the footer object to be centered. Otherwise it defaults to the full width of the page and the auto margin for the left and right get set to 0. If you want the footer bar to take up the width (like the StackOverflow notice bar) and center the text, then you need to add "text-align: center" to your definition.

here is an example using css grid.

html, body{
    height: 100%;
    width: 100%;
}
.container{
    height: 100%;
    display:grid;
    /*we divide the page into 3 parts*/
    grid-template-rows: 20px auto  30px;
    text-align: center;   /*this is to center the element*/ 
    
}

.container .footer{
    grid-row: 3;   /*the footer will occupy the last row*/
    display: inline-block;
    margin-top: -20px;
}
<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <link rel="stylesheet" href="style.css">
    <title>Document</title>
</head>
<body>
    <div class="container">
        <div class="header">

        </div>
        <div class="content">

        </div>
        <div class="footer">
            here is the footer
        </div>
    </div>
</body>
</html>

you can use css grid:a concrete example
