Unable to center text between two images - css

Question

I'm using the technique in Stack Overflow question CSS centering text between two images but am unable to make the text center.
I would like the text "0 of 0" centered in this markup (as a fiddle):
HTML:
<div id="invoiceImageContainer">
<img src="http://i.imgur.com/8QT8u.png" id="invoiceImage">
<div id="invoiceNav">
<img title="Next" src="http://i.imgur.com/oZb7r.png" id="nextInvoice">
<img title="Previous" src="http://i.imgur.com/aKi11.png" id="prevInvoice">
<span id="invoiceCount">0 of 0</span>
</div>
</div>
CSS:
#invoiceImageContainer{
width:420px;
margin: 0 auto;
}
#invoiceImage {
height:600px;
}
#invoiceNav {
color:black;
font-size:10pt;
}
#prevInvoice {
float:left;
padding-left:100px;
}
#nextInvoice {
float:right;
padding-right:100px;
}
#invoiceCount {
text-align:center;
}
What am I doing wrong?

Answer 1

You are using a span for the text container which is an inline element. Therefore its width is the same as the width required for its content, changing it to a p (or changing display to block) will allow for horizontal centering. If you want to center vertically then set the line-height equal to the height of the images and set vertical-align: middle.

Good old quick hack:
#invoiceImageContainer{
width:420px;
margin: 0 auto;
}
#invoiceImage {
height:600px;
}
#invoiceNav {
color:black;
font-size:10pt;
text-align:center;
}
#prevInvoice {
float:left;
padding-left:100px;
}
#nextInvoice {
float:right;
padding-right:100px;
}
#invoiceCount
{
line-height: 35px;
}
In your original markup you had #invoiceCount set to text-align:center. This is wrong because you can't center spans in that way, so I moved it to your container div.
The quick hack is the line-height, set to approximately the known size of your image. This technique is good and safe when you are doing a single line of text and the size of the elements involved is known.

This will fix it:
/* should be block level element */
#invoiceCount{
display: block;
}

Answer 4

You could add the following to the CSS of #invoiceNav
text-align: center;
line-height: 32px;
the first centers the <span> element and the second centers the text vertically in the <div> (same height as the images)

Answer 5

The problem is caused by the fact that doesn't support "width", since it's an inline block. The following changes will do the trick: in HTML change <span id="invoiceCount">0 of 0</span> to <div id="invoiceCount">0 of 0</div> and in CSS add width to the #invoiceCount like this:
#invoiceCount {
text-align:center;
width: 100%;
}
