Lesson 1 – Customize Child Themes with Background Images & Colors

This is the first lesson in our Customize Genesis Like a Pro video tutorial series. In this lesson we look at customizing various Genesis 2 Child Themes using background images and colors. In this class we introduce basic CSS syntax for editing your child theme.
We start off by looking at background images and how they can be used. Then we use a tiling background image to add a custom look to our skin. We take a look at ways to use multiple background images in the same HTML element. Next we look at using fixed background images and overlay that with semi-transparent colors. We also look at using the Genesis body class system to allow us to style various pages differently. We wrap it up by looking at changing background images for various mobile devices.
