I certainly do not want to add to the pile of vertical alignments
CSS questions, but I've spent hours trying to find a solution to no avail yet. Here's the situation:
I am building a slideshow gallery of images. I want the images to be displayed as large as the user's window allows. So I have this outer placeholder:
<section class="photo full">
(Yes, I'm using HTML5 elements). Which has the following CSS:
section.photo.full {
display:inline-block;
width:100%;
height:100%;
position:absolute;
overflow:hidden;
text-align:center;
}
Next, the
image is placed inside it. Depending on the orientation of the
image, I set either the width or height to 75%, and the other axis to auto:
$wide = $bigimage['width'] >= $bigimage['height'] ? true: false; ?>
<img src="<?= $bigimage['url'] ?>" width="<?= $wide? "75%" : "auto"?>" height="<?= $wide? "auto" : "75%"?>"/>
So, we have a fluid outer container, with inside a fluid
image. The horizontal centering of the
image works, yet I cannot seem to find a way to vertically center the
image within it's container. I have researched centering methods but most assume either the container or
image has a known width or height. Then there is the display:table-cell method, which does not seem to work for me either.
I'm stuck. I'm looking for a
CSS solution, but am open to js solutions too.
