I find it&#x27;s better to be aware of&#x2F;vigilant about the common bugs in flexbox&#x27;s implementation, and explicitly fix specific problems as you encounter them. I&#x27;ve never found a polyfill that doesn&#x27;t rely on hacks that lead to even-harder-to-fix problems.<p>It would be great for there to be a sort of CSS linter that could help here, but I haven&#x27;t found one yet.
