How to Declare A Child Theme

Create a new folder in your theme folder. I would only use lower case letters and dashes (-) in your theme name. Inside your new theme folder, copy the header text in your parent theme style.css file. To declare a parent theme, you will need to declare a Template. You will also need to change your Theme Name, Theme URI, Author, Author URI, and Text Domain. Here is an example below using the Meadowbrook theme as my parent theme.

/*
Theme Name: Angie Makes Knowledge Base
Theme URI: http://angiemakes.com
Description: Knowledge Base Child Theme for Angie Makes
Author: Angie Makes
Author URI: http://angiemakes.com
Template: meadowbrook-premium
Version: 1.0.8
Tags: black, blue, brown, gray, green, orange, pink, purple, red, silver, tan, white, yellow, dark, light, one-column, two-columns, three-columns, four-columns, left-sidebar, right-sidebar, fixed-layout, fluid-layout, responsive-layout, custom-background, custom-colors, custom-header, custom-menu, editor-style, featured-image-header, featured-images, front-page-post-form, full-width-template, post-formats, sticky-post, theme-options, threaded-comments, translation-ready
Text Domain: wpcanvas2-child
*/


/* =Theme customization starts here
-------------------------------------------------------------- */

By default, WordPress will not load the parent style.css file. So you will need to add the following code to your functions.php.

function wpcanvas2_child_enqueue_parent_theme_style() {
	wp_enqueue_style( 'parent-style', get_template_directory_uri().'/style.css' );
}
add_action( 'wp_enqueue_scripts', 'wpcanvas2_child_enqueue_parent_theme_style' );
