Slaying the Dragon: Refactoring CSS Using Sass
Refactoring is a practice that is often overlooked when it comes to CSS. As a result, styles seem to just grow and grow, until no one knows for sure which styles apply where, or whether many rules are still used at all. In this talk, we’ll cover strategies for refactoring CSS using Sass, with a focus on maintainability of code. Topics include code organization, naming, incremental change, and handling special cases such as responsive styles.
This talk is based on my experience refactoring thousands of lines of CSS into Sass, in a way that allowed for continuous feature development, as well as supporting multiple layers of responsive styles and device-specific styles.
The slides will contain fire-breathing dragons 🐉 and kittens 🐱.
