Creating a VS Code Theme

Combining the Powers of SEM and BIO for Improving CSS
4.6.2018
CSS is easy, some might argue, but that "easiness" can cause messy code. This is especially true through power of preprocessors like Sass or Less where, if you aren’t careful, your CSS can become harder to deal with instead of easier. Sass? Harder? This Gist shows a great example of Sass nesting...
