The internet is a wonderful network. Despite being built on nothing but aging hardware and infrastructure not designed to withstand the use we are now putting it through, the advantages of it as a platform far outweigh the cons. It's (mostly) global, so your information can reach the largest audience imaginable.
So, relatively recently I wrote a post praising the CSS Grid system of styling websites and web applications. From the ease of implementation and use, to the fact that you have minute control over each element of your site, while still having a seamless transition from mobile to desktop, Grid is something I still recommend highly today.
