Answer 1

Using a Flexbox worked for me:

#manipulate {
  position: absolute;
  width: 100%;
  display: flex;
  justify-content: center; // Centers the item
  bottom: 10px; // Moves it up a little from the bottom
}

Answer 2

You can center it using negative margins BUT please note that it'll center exactly on the center of the screen IF any containing div is NOT SET to position:relative;

For example. http://jsfiddle.net/aWNCm/

So, best way to exactly center this div is to set correct properties position properties for its containing divs too otherwise it will be lost in some random ways.

Answer 3

Use negative margins:

#manipulate
{
  position:absolute;
  width:300px;
  height:300px;
  margin-left:-150px;
  background:#063;
  bottom:0px;
  left:50%;
}

The key here is the width, left and margin-left properties.

Answer 4

Here is a solution with two divs:

HTML:

    <div id="footer">
        <div id="center">
            Text here
        </div>
    </div>

CSS:

#footer {
    position: fixed;
    bottom: 0;
    width: 100%;
}
#center {
    width: 500px;
    margin: 0 auto;
}

Answer 5

align="center" has no effect.

Since you have position:absolute, I would recommend positioning it 50% from the left and then subtracting half of its width from its left margin.

#manipulate {
    position:absolute;
    width:300px;
    height:300px;
    background:#063;
    bottom:0px;
    right:25%;
    left:50%;
    margin-left:-150px;
}

Answer 6

If you aren't comfortable with using negative margins, check this out.

HTML -

<div>
 Your Text
</div>

CSS -

div {
  position: fixed;
  left: 50%;
  bottom: 20px;
  transform: translate(-50%, -50%);
  margin: 0 auto;
}

Especially useful when you don't know the width of the div.
