// UPDATE: In 2023, you should probably stop using this! The narrow version of Safari that | |
// does not support `nomodule` is probably not being used anywhere. The code below is left | |

/** | |
* Safari 10.1 supports modules, but does not support the `nomodule` attribute - it will | |
* load <script nomodule> anyway. This snippet solve this problem, but only for script | |
* tags that load external code, e.g.: <script nomodule src="nomodule.js"></script> | |

* Again: this will **not** prevent inline script, e.g.: |

Hello, visitors! If you want an updated version of this styleguide in repo form with tons of real-life examples… check out Trellisheets! https://github.com/trello/trellisheets
“I perfectly understand our CSS. I never have any issues with cascading rules. I never have to use !important
or inline styles. Even though somebody else wrote this bit of CSS, I know exactly how it works and how to extend it. Fixes are easy! I have a hard time breaking our CSS. I know exactly where to put new CSS. We use all of our CSS and it’s pretty small overall. When I delete a template, I know the exact corresponding CSS file and I can delete it all at once. Nothing gets left behind.”
