<div id="resize-div">
<img src="someimage.jpg", :id="resize-div">
</div>

For the dimensions of the div, you can set it inline or use css file:

#resize-div {
width:466px;
height:133px;
}

Now since not all images will fit this aspect ratio you’ll encounter problems easily enough. With images smaller than the div, I had little problem letting the css to handle it so it’s situated perfectly center in the div. I didn’t include it here to shorten the codes i need to display .

Judging from the code shown above, you’ll not that if you have larger images that exceeded the div’s set height and width (especially those width different aspect ratios), a pure css solution simply won’t work (or at least I couldn’t make it work…. :/) so I thought of using JQuery to work it out for me.

Here’s my script to autofit images in a div using JQuery.

$(function(){
	var divElem = $("#resize-div");
	var maxht = divElem.height();
	var maxwdt = divElem.width();
	var imgElem = $("#resize-image");
	var ht = imgElem.height();
	var wdt = imgElem.width();
	if (ht < wdt){
		if (wdt > maxwdt)
			$("#resize-image").css({'height' : "auto", 'width' : maxwdt});
		else
			$("#resize-image").css({'height' : "auto", 'width' : wdt});
	}
	else if (ht > wdt){
		if (ht > maxht)
			$("#resize-image").css({'height' : maxht, 'width' : "auto"});
		else
			$("#resize-image").css({'height' : ht, 'width' : "auto"});
	}
});

The problem:

Turns out that datequery relies on an elements ID.  The problem?  Facebox duplicates all the contents of the div you wanted to display and all hell breaks loose.

The solution:

Quite simple actually.

Just use jQuery to replace the element id within facebox at run time.

Here’s the script:

$(document).bind('reveal.facebox', function() {
  $('#facebox .datepicker').each( function(intIndex){
    $(this).attr('id',jQuery(this).attr('id') + '-2')
  });
});

Then just modify your binding for datepicker accordingly:

$(document).bind('reveal.facebox', function() {
	$('#date_filed_for-2').datepicker();
})

And you’re done.
