This lesson series takes beginners from no knowledge of HTML, CSS and PHP to being fully capable of customizing Genesis. You'll need no prior knowledge of CSS, HTML or PHP. If you already have Genesis activated on a WordPress site and are comfortable with the basics of WordPress then this is a great place to start.
WordPress is great because it doesn't force you to learn HTML to use it. However, many folks find that not knowing HTML places limitations on what they can do. Unfortunately learning HTML can be an arduous process, especially because much of what you would typically learn isn't relevant in WordPress. This seminar bridges the gap between learning HTML and leaning HTML that will be useful to you as a WordPress (and Genesis 2) user.
