Equal Heights For WordPress Image Gallery Captions

This gives your WordPress image captions equal heights on a gallery page. The text captions will take the height of the tallest caption on the page.

This applies to the “gallery-caption” element, not to the entire “gallery-item” element. This is useful if you added a background color for your “gallery-caption” or “wp-caption-text“. Captions with a background color in a gallery may look better if they are the same height.

This uses jQuery, so you must include jQuery for this to work. Instead of using wp_enqueue_script to load a small external .js file, this loads the JavaScript inline into wp_head. This is recommended for faster page speed.

* Make the WP image gallery captions have equal heights on a gallery page.

function isa_equalheight_gallery_captions() {
	?><script>(function(jQuery){jQuery.fn.equalHeights=function(minHeight,maxHeight){tallest=(minHeight)?minHeight:0;this.each(function(){if(jQuery(this).height()>tallest){tallest=jQuery(this).height()}});if((maxHeight)&&tallest>maxHeight)tallest=maxHeight;return this.each(function(){jQuery(this).height(tallest)})}})(jQuery)

      They look aligned on your shop page. But to be sure that they remain aligned, you can use the function above, but change ‘.gallery-caption’ on lines 8 and 9 to ‘.custom-attributes’. Also, for this to work, you will have to add this CSS:

      .custom-attributes{ display:block; }

          It could go in your theme’s functions.php file. However, if you update your theme, the change will be overridden. I see that you’re using the Canvas theme. You can create a child theme and place the code in the child’s functions.php where it will remain even after updates.

          However, the line of CSS that I pasted above is not part of the function. Since you’re using a WooCommerce theme, you should be able to add the CSS into the Custom CSS area in your Canvas Theme Options. Hope that helps.
