Responsive web design is a must these days but it can be a little tricky to make your design work on all devices and screen sizes, especially if you have to start from scratch each time. Front-end frameworks make it very easy to quickly create responsive, standard-complaint websites by providing a reusable structure (HTML, CSS, JS), with configurable components, that allows you to hit the ground running with minimum effort. And the two most powerful frameworks? Bootstrap and Foundation. Rachel has used both Bootstrap and Foundation with numerous WordPress projects and will not only show you how to get started using these frameworks, but will also present a comparison of these two systems and the differences you’ll face when using them to create a WordPress theme.
