Make any featured image in WordPress Genesis the parallax scrolling background for your post or page. A top margin is added if there is no featured image and you have a fixed navigation bar like I did.
A working demo can be seen on FlyingEyes.biz, which is what I made this solution for.
More detailed step-by-step instructions can be found on my blog.
What problem this solves
If you want to easily change out the background image for a parallax scrolling page or post, you need to get this!
What this is
Inspired by WevoStudio's tutorial for parallax scrolling implementation for Wordpress, I decided to improve it by making it super-easy to use. Literally, just set a featured image for any page or post, and let 'er rip!
The "parallaxfunction.php" is a snippet that needs to go into your child theme's functions.php file. I'll likely implement this as a plugin in the future, but the snippet is very short so it's not much fuss.
If you don't want a particular page or post (or category, or post type, etc) to have this feature, just use conditional tags around the function.
"parallaxstyle.css" is a snippet that styles the new sections. Insert into your child theme's style.css file, and modify as needed.
