Ready for your next WordPress challenge? Learn how to build more complex custom themes using the _s (aka Underscores) starter theme. Morten Rand-Hendriksen takes you from basic layout and customization to enabling advanced responsive design and accessibility features. He reinforces the basics lessons with DRY (don't repeat yourself) development practices and a structured approach that will help you build WordPress themes that meet modern standards. Plus, he explores core concepts like understanding the WordPress template hierarchy and mobile-first design, creating functions, adding custom javascript, applying styles, and more. Plus, for 2016, we're including an all-new chapter on the Customizer, which provides controls that allow users of your theme to adjust the colors and layout.
