Tips for replicating background-image appearance while ensuring compatibility with printing requirements

Is there a way to crop images horizontally using CSS, while keeping the images visible during printing? I am currently utilizing background-image to crop images to a width of 200px without knowing the image widths in advance. My goal is to have the middle of the image displayed.

 .cropped-image {
    width: 200px;
    height: 270px;

    /* Centered, cropped image */
    background-position: center;
    background-repeat: no-repeat;
}

This is how my HTML template is structured:

    <div class="cropped-image" style="background-image: url({{ product.image_thumb_url }})">
    </div>

An example showcasing this functionality can be viewed here: http://jsfiddle.net/hRSdY/

While this method works effectively, default web browsers do not print background images. It is possible to use list-style-image as an alternative to emulate background-image, however, cropping to the center of the image becomes challenging: http://jsfiddle.net/KP7ng/1/.

Answer №1

If the images have arbitrary dimensions, CSS alone cannot reposition them.

To achieve this, javascript must be used to adjust their position after they are loaded.

An example using jQuery would look like:

$(window).load(function(){
    $('.cropped-image img').each(function(){
        var self = $(this);
        self.css({
            marginLeft: (-this.width/2),
            marginTop: (-this.height/2),
            visibility: 'visible' /*set to visible once loaded and repositioned*/
        })
    });
});

The HTML structure should be:

<div class="cropped-image">
   <img src="{{ product.image_thumb_url }}"/>
</div>

And the necessary CSS:

.cropped-image {
    width: 200px;
    height: 270px;
    position:relative;
    overflow:hidden;
}
.cropped-image img{
    left:50%;
    top:50%;
    position:absolute;
    visibility:hidden; /*set to hidden until the page is loaded to avoid moving images*/
}
