Reduce the JS Workload with No- or Lo-JS options.
For years, JavaScript has been the web’s workhorse. If HTML or CSS couldn’t do what we wanted, we grabbed JavaScript to do it.

This is an organic collection of common JS patterns that can be replaced with just HTML, CSS, and no, or very low, JS. As HTML and CSS continue to mature, this collection should expand.
