Falling in Love with Sass for WordPress — Frederick Meyer
Learn why Sass, the CSS preprocessor, is better than vanilla CSS for complex projects, based on two key qualities of Sass: 1. It’s DRYer, and 2. It’s dynamic. The talk describes these benefits with reference to a complex real-life client project: creating a user-managed WordPress theme generator, with widths, color scheme, typography, etc., all changeable as Sass variables, compiling to one clean custom CSS stylesheet with no extra “theme options” DB calls.

We walk through what Composer is, how to use it, then see how we can integrate it with our own WordPress projects, whether that’s a theme, plugin, or an entire WordPress site.
