In this chapter we've covered tooling to facilitate constant code quality and an improved style sheet authoring experience. However, you should be aware that out of everything we have covered, the specific tools listed here are likely to be the most short-lived. Tooling technology moves at a blistering pace. In just three years I went from vanilla CSS, to Sass (with scss-lint (https://github.com/brigade/scss-lint)), to PostCSS and Stylelint while also moving from GUI build tools like CodeKit to JavaScript build tools Grunt, then Gulp and now NPM scripts.

I have no idea what the best choice will be in 6 months time so the take away is to think about how tooling and approaches can improve the style sheet authoring experience across your teams, not necessarily what the current tools are.
