Maintaining the CSS for any web site or app can be extremely challenging as the product and the team supporting the product grows. This course examines a suite of tools and processes you can use in your development workflows to keep your CSS healthy and consistent. We'll run CSS analysis tools (e.g., Lighthouse, CSS Stats, CSS Dig, etc.) on a set of popular travel sites to highlight the CSS issues on those sites; we'll survey the suggestions for resolving those issues; and then we'll examine a group of highly effective processes and monitoring tools that help teams maintain their style guide CSS and product CSS. Learners should have a solid understanding of basic CSS and HTML.
