- I added a fallback for browsers that can’t render CSS Grid to ant33t.rocks with Flexbox and the
@supportsrule. Fallbacks don’t have to look identical - they should provide a usable experience.
- I learnt to avoid using index for React list keys because of their unreliability.
- I read about CSS rendering and the CSSOM and found it really interesting - browser performance is something I know I should have a deeper knowledge of but always neglect.
