These are the latest Genesis child themes from StudioPress. They’re built on Genesis 2.0, come with HTML5 and schema.org markup and are all mobile responsive.
HTML5 markup makes your website future compatible, improves cross-browser compatibility and makes your site truly mobile-friendly. If you want to know more take a look at Top ten reasons to use HTML5 right now.
Schema.org allows you to classify the most important and defining elements on your pages and posts. This enhances your site’s search results display by allowing the search engines to add extra data. For a great explanation check out Joost de Valk’s article Schema.org & Genesis 2.0.
The themes can be bought individually or you can buy them all, plus all future StudioPress themes, for a one-off payment with the StudioPress Pro Plus All-Themes Package.
At the moment there are forty HTML5 ready themes (plus the Genesis theme framework), but StudioPress are releasing new themes on a regular basis… so keep checking back.
