Foundation is one of the most popular responsive design frameworksclean and simple. But much of Foundation's styling is accomplished via slightly more complex CSS: Compass and Sass. This course with Jen Kramer shows how to install Foundation, Compass, and Sass, and customize your own Foundation site. Learn how to start a new project, navigate the Sass file structure, and use the main _setting.scss file to style color, fonts, spacing, and more. Plus, learn about advanced features like functions, mixins, extended styles, and much more.
