Genesis Code Snippets

My collection of code snippets I use build child themes in Genesis

Here is my collection of code snippets I use build child themes in Genesis.

If it's not here, please check out Bill Erickson's Genesis Quick Tips, Gary's Code, or Brian Gardner's Code. Thanks to Gary J for advice on cleaning up the code snippets to adhere with coding standards.

NOTE: While all of these functions still work, some may not with Genesis 2.0's new hook structure. Check out this visual guide to make adjustments.

Custom Header Support

/** Add custom header support */
add_theme_support( 'genesis-custom-header', array( 'width' => 960, 'height' => 100, 'textcolor' => '444', 'admin_header_callback' => 'minimum_admin_style' ) );

/** Remove Header */
remove_action( 'genesis_header', 'genesis_do_header' );

/** Remove Title & Description */
remove_action( 'genesis_site_title', 'genesis_seo_site_title' );

 * Then add title back to header.
 *

 */
function child_seo_site_title() {

 echo '<h1 id="title"><span>Buzz</span>Montgomery.com</h1>';

}
