Frontend Focus

? Hey, it’s good to be back in your inbox with the very first Frontend Focus of the new year. After the holiday break, we’re back on our regular schedule, so you can expect this digest each and every Wednesday.

As it’s the new year, here’s a little PSA to kick things off: don’t forget to update the copyright year in your footer. ?

If you missed our last issue of 2019, it took a look back at some of the highlights of the past twelve months in all things HTML, CSS and browsers — that roundup is now available on the web, and you can find it here.

Finally, I just wanted to extend a thanks once again for reading this newsletter. If you’ve ever got any comments or links you want to share, just hit reply.
