If it’s not possible to customize some layout using CSS, you can override HivePress layouts by placing template files inside the “hivepress” folder within the current theme folder. For example, you can override the single listing layout by placing
hivepress/listing/content-single.php file within the theme folder and then customize it. You can find a list of available template files on GitHub.
Also, if you’re familiar with PHP, you can customize layouts using hooks.
