Confused? Don’t worry, we’ll clear things up here.
Think of the whole thing like this: Imagine you have a house, and with one click of a button on a magical remote, you can change the layout, style, and furnishings to match those of a home on the page of a Better Homes & Gardens magazine.
Let’s break it down
WordPress: This is the foundation and core of your website. Think of it like an empty house with white walls.
Genesis Framework: This is like the magical remote that allows you to apply a style, design, and furnishings to your blank house.
Themes: These are like the pages of a Better Homes & Gardens magazine that show all different kinds of home styles, layouts, colors, decors, furnishings etc.
Still Confused? Maybe a visual will help.
