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.
