Prudence 2018 was a theme released in January 2018 as a part of Aurora Update 11. Similar to Hale 2015, Prudence 2018 adapted the Prudence design and kept the powerful features of Sherman. A child of the Cornerstone theme, Prudence 2018 will continue to benefit from all new features added to Aurora for years to come.

Child Theming with SASS
Child Theming with CSS
Cornerstone was built with SASS, but you can still develop with normal CSS.
Don’t use @import in your CSS file, or your site will break in IE8.
Instead, add this to your functions.php file:
<?php function link_parent_theme_style() { wp_enqueue_style( 'parent-style', get_template_directory_uri() . '/style.css' ); wp_enqueue_style( 'child-style', get_stylesheet_uri() ); } add_action('wp_enqueue_scripts', 'link_parent_theme_style'); ?>
Typically, a child theme will @import the css of the parent theme. Bootstrap 3, the framework which Cornerstone is based on, offers very limited support for Internet Explorer 8. By default, a Bootstrap 3 site in IE8 will render the mobile view. One column of content, and the collapse mobile navigation.
Being that IE8 accounts for a sizable (~7%) of traffic on Aurora, Cornerstone makes use of respond.js, which uses javascript to mimic media queries for IE8. However, respond.js will not work on anything loaded via @import. So this alternate method is required.
Child Themes
Child themes are a way to take an existing theme, such as Sherman, and change a couple of things about it. For developers looking to create something custom, we highly recommend looking into child themes first.
