Good Mobile Responsive WordPress Themes are scattered throughout numerous websites, and many of the better ones are on commercial sites that offer (for a price) Child Themes based upon their proprietary Frameworks. StudioPress and their Genesis Framework is a good example of this. They are currently undergoing a rewrite of as many of their Child Themes as possible into a Mobile Responsive Format. Other WordPress Theme developers are still producing both Responsive and Non-Responsive themes, based upon the sales statistics they get from their customer base. I was browsing the Web looking for New, Free, Mobile Responsive WP Themes, and came across the Alien WP website. Galin Simeonov is the site’s developer, and he currently offers three WP Themes based upon the Hybrid Core. They all require a minimum version of WordPress 3.3, PHP 5.2.4, and MySQL 5.0 to work properly. Galin is designing for the future, not backwards compatibility (“more power to him”). Here are links to his theme demos, all of which use attractive images of women for their feature illustrations ( I only found a surreal image of a young girl and her dolphin ).
As you go through the demos, drag the right edge of your browser window from right-to-left, and watch how the Theme Layouts are restructured to fit the viewport size. Also, use both of these Free Screen Layout Testing Tools to check each Theme’s adaptation to various mobile devices:
Good Luck, and I hope you like them (they are currently Free!)
